How to solve the addition of integers?
To add integers having the same sign, keep the same sign, and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.
How to solve the subtraction of integers?
To subtract integers, change the sign on the integer that is to be subtracted. If both signs are positive, the answer will be positive. If both signs are negative, the answer will be negative. If the signs are different subtract the smaller absolute value from the larger absolute value.

Answer:
ST = 52
SW = 54
WV = 54
Step-by-step explanation:
Because TW is a median line, that means that SW and WV are the same length. So, SW = WV or:
2x + 30 = 5x -6
We can then rearrange to have all the x's on one side like so:
2x - 2x + 30 = 5x -2x -6
30 = 3x -6
30 + 6 = 3x -6 +6
36 = 3x
Then, we divide both sides by 3 to find x by itself:
[tex] \frac{36}{3} = \frac{3x}{3} [/tex]
12 = x
To finish, replace x with 12 in each equation:
ST = 12 + 40
ST = 52
SW = 2(12) + 30
SW = 24 + 30
SW = 54
WV = 5(12) -6
WV = 60 -6
WV = 54

for example, 1÷1 equals one. a number that is the same divided is always 1. another example. 2÷2 is 1.
Answer: The answer is 1
Step-by-step explanation:Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
149×914=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
14×99×14=126126
Since 126 divided by 126 equals 1 then,
126126=1
Therefore:
149÷149=1
Solution by FormulasApply the fractions formula for division, to
149÷149
and solve
14×99×14
=126126
=1
Therefore:
149÷149=1

PLZ HELP LAST QUESTION given the piecewise function given below select all statements that are true f(x)=-x+1,x<0 -2,x=0 x^2-1,x>0 All in brackets A.F(4)=7 Bf(-1)=2 c.F(-2)=0 d.F(1)=0
Answer:
Step-by-step explanation:
Given the function f(x)=-x+1,x<0 and f(x) = x^2-1,x>0
when x = 4
f(4) = -4+1
f(4) = -3
Also f(4) = 4^2 -1
f(4) = 8-1
f(4) = 7
when x = -1
f(-1) = -(-1)+1
f(-1) = 2
Also f(-1) = (-1)^2 -1
f(-1) = 1-1
f(-1) = 0
when x = -2
f(-2) = -(-2)+1
f(-2) = 3
Also f(-2) = (-2)^2 -1
f(-2) = 4-1
f(-2) = 3
when x = 1
f(1) = -1)+1
f(1) = -2
Also f(1) = (1)^2 -1
f(1) = 1-1
f(1) = 0
From the calculation above, the correct statements are
A. F(4)=7
B f(-1)=2
d. F(1)=0
1) Jon is standing 60 feet from the base of a cliff watching a friend, Marvin, prepare to bungee jump. The angle of elevation to the top of the cliff is 73º. How high is the cliff Marvin is jumping from?
Answer:
196 feet
Step-by-step explanation:
Let be A the point where Jon is standing, B the point at the base of the cliff and C the point where Marvin is standing, this situation resemble to a right triangle .AB us the distance from the base of the cliff, that is 60 feet.
m<BAC is 73° .We need to find BC.
Right angle is <ABC
tan73°=BC/AB
tan73°=x/60
x=tan73°*60=3.27*60=196 feet approximately.
Una escalera está apoyada sobre la pared que mide 3.5m. El pie de la escalera hasta la pared mide 2.5m ¿Cuánto mide la escalera?
Responder:
Explicación paso a paso:
La configuración formará un triángulo de ángulos rectos.
Deje que el pie de la escalera a la pared sean los lados adyacentes = 2,5 m
La altura de la pared será el lado opuesto = 3,5 m
La longitud de la escalera será la hipotenusa.
Usando el teorema de Pitágoras:
hip² = opp² + adj²
hip² = 3,5² + 2,5²
hip² = 12,25 + 6,25
hip² = 6
hip = √6
hip = 2,45 m
Por tanto, la longitud de la escalera es 2,45 m.
A public health researcher wishes to study the dietary behavior of residents in Durham County. The researcher randomly contacts 35 county residents and collects data on their daily sugar intake and obtained a sample average of 37.4 grams sugar per day and a sample standard deviation of 4.2 grams per day. The researcher would like to construct a 99% confidence interval for the mean daily sugar intake of residents in the county using the data. Which distribution should the researcher use when analyzing these data?
Answer: The researcher should use a t-distribution because they do not know the true standard deviation of daily sugar intake in Durham county
Step-by-step explanation:
Given data:
No of county residents contacted = 35
Sample average = 37.4grams
Standard deviation = 4.2.
Confidence interval.
From the given data above it is obvious that the research doesn’t know the true data for standard deviation of the daily intake of sugar in Durham. And as such the best distribution method that can be employed by the researcher to solve this problem would be the T-distribution.
The equation below shows the total volume (V), in cubic units, of 4 identical boxes with each side equal to s units: V = 4s3 If s = 2.5 units, what is the value of V?
Answer:
The total volume is 62.5.-
Step-by-step explanation:
Giving the following information:
The equation below shows the total volume (V), in cubic units, of 4 identical boxes with each side equal to "s" units:
V = 4*(s^3)
Now, the total volume if s=2.5:
V= 4*(2.5^3)
V= 4*15.625
V= 62.5
The total volume is 62.5.-
Answer:
30 square units
Step-by-step explanation:
4 x 2.5 units= 10.
take the 3 from the V, (4s³).
Multiply that.
4 x 2.5 square units = 10
10 x ³ = 30 square units In total.

If angle 1 and angle 3 are vertical angles, and m<1= (5x + 14) degrees and m<3= (7x - 4) degrees, what is the value of x, and the measure for angle 1?
Answer:
x = 9
[tex] m\angle 1= 59\degree [/tex]
Step-by-step explanation:
Since, [tex] \angle 1 \:and \:\angle 3[/tex] are vertical angles.
[tex]\therefore m\angle 1 = m\angle 3\\
\therefore (5x + 14) \degree= (7x - 4) \degree\\
\therefore (5x + 14) = (7x - 4) \\
\therefore 5x - 7x = - 4 - 14\\
\therefore -2 x = - 18\\\\
\therefore x =\frac{-18}{-2}\\\\
\huge \orange {\boxed {\therefore x = 9}} \\\\
m\angle 1 = (5x + 14) \degree\\
m\angle 1 = (5\times 9+ 14) \degree\\
m\angle 1 = (45+ 14) \degree\\
\huge \purple{ \boxed{m\angle 1 =59\degree}}[/tex]
Isaac read that 32% of people owned dogs. What decimal represents the portion of people who
do not own dogs?
The 0.68 decimal represents the part of humans who do not own dogs.
What is proportionality?the property of having suitable proportions in terms of size, number, degree, harshness, etc. If a defensive action against an unfair attack results in destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
Given, Isaac read that 32% of people owned dogs.
Thus,
We can say the portion of people who owned dogs = is 32% of * the total number of people
the portion of people who owned dogs = 0.32* total people
So,
The portion of people who Do not own dogs will be = 1 - 0.32* total people
The portion of people who Do not own dogs will be = 0.68 total people

Tangela earns the same amount each week by babysitting. When she started this job, she had $200 in her savings account.
The table shows Tangela's savings account balance for her first month of work.
Week 0 1 2 3 4
Balance $200 $350 $500 $650 $800
Let x represent the number of weeks Tangela has been working and let y represent Tangela's account balance.
Which equation, expressed in Slope-Intercept form, represents the amount of money in Tangela's bank account over time?
Answer:
y = 150x + 200
Step-by-step explanation:
Given the table :
Week (x) __ 0 ____ 1 ____ 2 ____3 _____ 4
Balance(y) :$200_ $350_ $500_ $650_ $800
Equation in slope - intercept form:
y = mx + c
Where
x and y are the independent(x) and dependent variables (y)
C = intercept, value of y, when x = 0
m = gradient change in y per change in x
Hence,
c = $200 ; y value when x = 0
m = change in x / change in y
m = (500 - 350) / ( 2 - 1)
m = $150
Hence, equation becomes :
y = 150x + 200
Lara has 2 pieces of string. One is 15 feet long and the other is 12. For an art project, she wants to cut them up to produce many pieces of string that are all of the same length with no string left over. What is the greatest length, in feet, that she can make?
Answer:
3 feet
Step-by-step explanation:
Lara has 2 pieces of string. One is 15 feet long and the other is 12.
We solve this question using the Greatest Common Factor method.
We have to find the factors of 12 and 15
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 15 are: 1, 3, 5, 15
Then the greatest common factor is 3.
Therefore, the greatest length, in feet, that she can make is 3 feet
