Answer:
for the first one, x + 3 * y = 5
and the second equation, x - y = 5
Step-by-step explanation:
the sum of two numbers means for example the sum of 5 and 8 is 13, so as an equation that is 5 + 8 = 13
the difference is the same thing as the sum but it's subtraction.
and then times is just multiplication.

Integers Multiple Choice Read the word problem and circle the corresponding expression. 1. Jaimie withdrew $25 from his TFSA (Tax-Free Savings Account), 4 times. Which expression shows the change in his savings account?
a) (-25)(4)
b) (-25)(-4)
c) −25 4
d) 25 4 2.
Answer:
a) (-25)(4)
Step-by-step explanation:
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations. In this case,
withdrew means no longer there which means subtracted.
Then, times mean multiply.
Therefore, -minus twenty-five times (x) four
combine them and it equals (-25)(4)
The population, P, of Johnstown over a period of t years since the town
was founded can be estimated by P = 5,600e0.0591
In approximately how many years after the town's founding will the
population reach 11,200?
Answer:
12 years
Step-by-step explanation:
Given that
P = 5,600 e^0.0591
Reaching amount = 11,200
time period = t
We need to find out the time period i.e. t
So,
11,200 = 5,600 e^0.0591t
2 = e^0.0591t
Now take the log on both the sides
ln2 = 0.0591t ln
t = ln2 ÷ 0.059
= 0.693147÷ 0.059
= 11.748
= 12 years

11) Prove quadrilateral ABCD is a parallelogram A(-2, 8), B(2, 7), C(5, 1), and D(1, 2) *
9514 1404 393
Explanation:
The quadrilateral will be a parallelogram if the diagonals bisect each other. That is, their midpoints are the same point. We don't actually need to calculate the midpoint. Rather, we can calculate the point that has double the coordinate values.
If (A+C) = (B+D), the quadrilateral is a parallelogram.
A +C = B +D
(-2, 8) +(5, 1) = (2, 7) +(1, 2)
(-2+5, 8+1) = (2+1, 7+2)
(3, 9) = (3, 9) . . . . . the figure is a parallelogram
_____
Of course, the midpoint of the diagonals is (3/2, 9/2).

What's the length of one leg of a right triangle if the length of the hypotenuse is 25 units and the length of the other leg is 25 units?
Answer:
0 units
Step-by-step explanation:
What's the length of one leg of a right triangle if the length of the hypotenuse is 25 units and the length of the other leg is 25 units?
The formula to solve for the sides of a right angled triangle
= Hypotenuse² = Opposite² + Adjacent ²
Hypotenuse = 25 units
One side = 25 units
To find the other side
√ 25² - 25²
= √625 - 625
= √0
= 0 units
The length of the other leg = 0 units
Given the side lengths, determine whether the triangle is acute, obtuse, right, or not a triangle
Answer:
Not a triangle

Substitute t = 3 and t = 6 to determine if the two expressions are equivalent.
3 (2 t + 5) 6 t + 15
Which statements are true? Select the three correct answers.
A. The value of both expressions when t = 3 is 33.
B. The value of both expressions when t = 3 is 23.
C. The value of both expressions when t = 6 is 41.
D. The value of both expressions when t = 6 is 51.
E. The two expressions are equivalent.
F. The two expressions are not equivalent.
Answer:
A.The value of both expressions when t=3 is 33.
D.The value of both expressions when t=6 is 51.
E.The two expressions are equivalent.
Step-by-step explanation:
We are given two expressions.
3(2t + 5)
6t + 15
Now let's find the value of these two expressions when t =3 and t = 6
When t =3, the value of the expressions:
3(2*3 + 5) = 3(6 + 5) = 3(11) = 33
6*3 + 15 = 18 + 15 = 33
So the value of both the expressions is 33 when t = 33.
When t = 6, the value of the expressions:
3(2*6 + 5) = 3(12 + 5) = 3(17) = 51
6*6 + 15 = 36 + 15 = 51
The value of both the expressions is 51 when t = 51.
So the following statements are true:
A.The value of both expressions when t=3 is 33.
D.The value of both expressions when t=6 is 51.
E.The two expressions are equivalent.

The Jacksons are taking out a $35,000 loan to remodel their home. The tables below show the rates for a 1-year and 5-year loan from two different lenders. Complete each table to calculate the total repayment and interest paid for each loan offer.
Answer:
look at the screenshot
Step-by-step explanation:
look at the screenshot
The table for total repayment and interest paid for each loan offer:
Loan offer Interest rate Total repayment Total interest paid
1-year loan 6.5% $37,275 $2,275
5-year loan 8.2% $41,570 $6,570
What is simple interest?Simple interest is an amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider: principal amount(P), rate(R) and time(T).
Formula; Simple Interest(I) = P × R × T/100
For the 1-year loan, the total repayment and total interest paid can be calculated as follows:
Total repayment = Principal + Interest = $35,000 + (0.065 x $35,000)
= $37,275
Total interest paid = $37,275 - $35,000
= $2,275
For the 5-year loan, the total repayment and total interest paid can be calculated as follows:
Total repayment = Principal + Interest
= $35,000 + (0.082 x $35,000 x 5)
= $41,570
Total interest paid = $41,570 - $35,000 = $6,570
Loan offer Interest rate Total repayment Total interest paid
1-year loan 6.5% $37,275 $2,275
5-year loan 8.2% $41,570 $6,570

Using 5 miles = 8 km, write 2 m/s in mph.
Give your answer as a decimal.
Answer:
4.5 mph
Step-by-step explanation:
2 m/s = (2 m/s)(60)(60) = 7200 m/h or 7.2 km/hr
if 5 miles = 8 km, then 1 km = 0.625 miles
7.2 x 0.625 = 4.5 mph
What is quotient of 2x3 + 3x2 + 5x - 4 divided by x2 + x + 1
The quotient is the outcome of the division one number or expression known as the dividend, by another number or expression known as the divisor
The option that gives the correct quotient is;
[tex]\mathbf{2\cdot x + 1 + \dfrac{2 \cdot x - 5}{x^2 + x + 1}}[/tex]
Where, the quotient is 2·x + 1, and the reminder is 2·x - 5
The reason the above option is correct is as follows:
The given dividend is 2·x³ + 3·x² + 5·x - 4
The divisor is x² + x + 1
By long division of a polynomial we have;
2·x + 1(Quotient)
(2·x³ + 3·x² + 5·x - 4) ÷ (x² + x + 1 )
2·x³ + 2·x² + 2·x
0 + x² + 3·x - 4
[tex]{}[/tex] x² + x + 1
[tex]{}[/tex] 0 + 2·x - 5
Therefore, we have;
[tex]\dfrac{2\cdot x^3 + 3 \cdot x^2 + 5 \cdot x - 4}{x^2 + x + 1} = 2\cdot x + 1 + \dfrac{2 \cdot x - 5}{x^2 + x + 1}[/tex]
Therefore, the correct option is;
[tex]\mathbf{2\cdot x + 1 + \dfrac{2 \cdot x - 5}{x^2 + x + 1}}[/tex]

4. ∠4 = 3x + 10, ∠6= 2x + 20
5. ∠1 = 7x + 9, ∠5 = 5x + 31
Plssss I need this now
Step-by-step explanation:
1. Angle 5 = 120 degree
Angle 5 = Angle 6 ( alternate exterior angles are equal )
Therfore, Angle 6 = 120 degree
Angle 6 = Angle 4 ( Vertically opposite angles are equal )
Therfore, Angle 4 = 120 degree
Angle 4 = 5x
120 = 5x
120/5 = x
40 = x
Therefore x = 40 degree.
2. Angle 1 = 100 degree
Angle 1 = Angle 7 ( vertically opposite angles are equal )
Therefore, Angle 7 = 100 degree
Angle 7 = 10x
100 = 10x
100/10 = x
10 = x
Therefore x = 10 degree

Manuel has scored 27,29 and 28 points in his three basketball games so far. How many points does he need to score in his next game so that his average (mean) is 28 points per game?
Answer:
28.71 points
Step-by-step explanation:
(27.29 + 28 + x) / 3 = 28
(27.29 + 28 + x) = 84
28 + x = 56.71
x = 28.71
The number of points he needs to score in his next game so that his average (mean) is 28 points per game will be 28.
What is mean?The mean is the average of a data set. Mean gives us an idea of that how much amount of overall data have.
Mean = sum of data / Number of data
As per the given,
Manuel has scored 27,29 and 28 points in his three basketball games so far.
Suppose his score in the fourth game is x.
Mean = (27 + 29 + 28 + x)/4 = 28
(84 + x)/4 = 28
84 + x = 112
x = 28
Hence "The number of points he needs to score in his next game so that his average (mean) is 28 points per game will be 28".
