Answer:
$25
Step-by-step explanation:
$40 + c = $65
65-40 = c
25 = c
Answer:
25
Step-by-step explanation:
40+c=65 isolate the c by subtracting 40 from both sides and you're left with 25. hope this helps

Rules of adding 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.
Rules of subtracting integer
First, keep the first number (known as the minuend). Second, change the operation from subtraction to addition. Third, get the opposite sign of the second number (known as the subtrahend) . Finally, proceed with the regular addition of integers.
Rules of multiplying and dividing integers
Multiplication and Division of Integers.
RULE 1: The product of a positive integer and a negative integer is negative. RULE 2: The product of two positive integers is positive.
RULE 3: The product of two negative integers is positive.

A student evaluates the equation y=2x+5 , using a variety of values for x . After evaluating the equation the student claims: "When x is a positive integer then y is also a positive integer and when x is a negative integer then y is also a negative integer." What is a value of x that proves that the student's claim is NOT true?
The length of a rectangle is three times its width. the perImeter of the rectangle is 100 inches. What are the dimension of the rectangle
Answer:
width is 12.5 inches
length is 37.5 inches
Step-by-step explanation:
x is width, 3x is length,
Double each and make it equal to 100, ie. 2x+6x=100Divide everything by two, x+3x=50Combine x and 3x, 4x=50divide broth sides by 4x = 12.5Since x is width, width is 12.5Length is 3x, so 12.5 * 3 is 37.5solve for f.
2 + 1.25f = 10 - 2.75f
Answer:
2
Step-by-step explanation:
2 + 1.25f = 10 - 2.75f
1.25f + 2.75f = 10 - 2
4f = 8
f = 8/4
f = 2

The daily energy requirement for males is modeled by the chart below. Age (Years) (X) Energy Needed (Calories) (Y) 1 1100 2 1300 5 1800 8 2200 11 2500 14 2800 17 3000 Use the points (5, 1800) and (17, 3000) to determine a linear equation for the data.
Answer: y = 100x + 1300
Step-by-step explanation: Linear Equation is an equation whose graphic produces a line. It is of the form y = mx + B, in which m and B are real numbers.
The term m is also the slope or gradient of the equation, i.e., it shows the steepness of the line. While B is y-intercept, i.e., it is the point where the line touches the y-axis.
The slope is determined by:
[tex]m=\frac{y-y_{0}}{x-x_{0}}[/tex]
[tex]m=\frac{3000-1800}{17-5}[/tex]
m = 100
For the linear equation, use:
[tex]y-y_{1}=m(x-x_{1})[/tex]
and point (5,1800):
[tex]y-1800=100(x-5)[/tex]
[tex]y=100x-500+1800[/tex]
[tex]y=100x+1300[/tex]
The linear equation of daily energy requirement for males is [tex]y=100x+1300[/tex].
A town's population is 42,750 . About 125 people move out of the town each month. Each month, 175 people on average move into town. A nearby town has a population of 45,450 . It has no one moving in and an average of 175 people moving away every month. In about how many months will the populations of the towns be equal? Write an equation to model the situation. Then solve the equation and answer the question.
Answer:

The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y-3 = {(x - 1). What is
the slope-intercept form of the equation for this line?
Answer:
u of the record for me and my family are doing well and that you have a meeting with the record for me and my family are doing well and that you have
Answer:
Step-by-step explanation:
Just rewrite y-3 = {(x - 1) as y-3 = m(x - 1). {(x - 1) is not valid.
Next, solve this y-3 = m(x - 1) for y:
Adding 3 to both sides yields y = m(x - 1) + 3, or:
y = mx - m + 3, or
y = mx + (-m + 3). This is in slope-intercept form.
If you choose m = 2, then the equation becomes
y = 2x +(-2 + 3), or:
y = 2x + 1
Note: to get a single answer to this question you must provide the m value.
CAN ANYONE HELP ME!!! URGENT.. WILL MARK BRAINLIEST!!!
Answer:
y= 5(1) = 5
Y= 5(2) = 10
y= 5(3) = 15
y= 5(4) = 20
y= 5(5) = 25
y= 4(1)+3 = 7
y= 4(2)+3 = 11
y= 4(3)+3 = 15
y= 4(4)+3 = 19
y= 4(5)+3 = 23
Step-by-step explanation:
you just have to substitute x in each equation for the number above.

What is the equation of the line that passes through the point (-5, -3) and has a
slope of -1
Answer:
The equation of the line is y = - x - 8
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptLet us solve the question
∵ The slope of the line is -1
∴ m = -1
→ Substitute it in the form of the equation above
∴ y = -1(x) + b
∴ y = - x + b
→ To find b substitute x and y in the equation by the coordinates of
a point lies on the line
∵ The line passes through point (-5, -3)
∴ x = -5 and y = -3
∵ -3 = - (-5) + b
→ Remember (-)(-) = (+) and (-)(+) = (-)
∴ -3 = 5 + b
→ Subtract 5 from both sides
∴ -3 - 5 = 5 - 5 + b
∴ -8 = b
→ Substitute it in the equation
∴ y = - x + (-8)
∴ y = - x - 8
∴ The equation of the line is y = - x - 8
What are the four properties of equality?
Answer:
1. The Reflexive Property. a =a
2. The Symmetric Property. If a=b, then b=a
3.The transitive Property. If a=b and b=c, then a=c
4. The Substitution Property. If a=b, then a can be substituted for b in any equation
Step-by-step explanation:
Answer:Addition property of equality, subtraction property of equality, multiplication property of equality, division property of equality
Step-by-step explanation: There’s also distributive property, reflexive property, symmetric property, transitive property, substitution property(. THOSE ARE NOT PROPERT OF EQUALITY)
A packet of crisp weighs 32 grams to the nearest gram. a multi-pack crisp contains 10 packets. work out the least and the greatest weighs of the multipack. ignore the weight of the multipack
Answer:
Least weight of multipack :
31.5 * 10 = 315g
Highest weight of multipack :
32.4 * 10 = 324g
Step-by-step explanation:
Weight of a packet of crisp to the nearest gram = 32 g
The least value of the weight of actual packet = 31.5 (least number which can give 32 when rounded to the nearest gram)
The highest value of the weight of actual packet = 32.4g (Highest number which can give 32 when rounded to the nearest gram)
Since a multipack contains 10 packets of crisp :
Least weight of multipack :
31.5 * 10 = 315g
Highest weight of multipack :
32.4 * 10 = 324g
-5(-5w+5)-7w=2(w-9)-3
Solve and check
Answer:
w = 1/4
Step-by-step explanation:
Expand the equation
25w - 25 - 7w = 2w - 18 - 3
Rearrange and put the like terms on either side
25w - 7w - 2w = -18 - 3 + 25
Simplify
16w = 4
Divide both sides by 16 to make the variable 'w' on its own
w = 1/4
5,000 books in the town's library of these 4,300are fiction. To find the percent of the books that are fiction, first set up the percent equation. Then find the percent.
Answer: 86%
Step-by-step explanation:
Number of books in the town's library = 5000
Number of books that are fiction= 4300
The percent of books that are fiction will be:
= 4300/5000 × 100
= 0.86 × 100
= 86%
