Answer:
x = 14
y = 40
Step-by-step explanation:
3y+8 = 128
3y = 120
y = 40
45/20=2.25 (scale factor)
5x-25 = 2.25(2x-8)
5x-25 = 4.5x - 18
.5x = 7
x=14

Nine years ago, Tarah opened a savings account with her bank. She started with a balance of $450 and has not made any withdrawals or deposits since then.
If her interest rate is 7% each year, how much interest has accrued using simple interest?
Answers
Answer:
Step-by-step explanation:
The interest accrued is $258.48.
Step-by-step explanation:
Given that:
Initial balance in the savings account = $359
Interest rate = 8%
Time for which no withdrawals or deposits were done = 9 years
To find:
Simple Interest accrued = ?
Solution:
First of all, let us have a look at the formula for simple interest.
Where P is the Principal Amount.
R is the annual rate of interest
T is the time in years.
Here, we are given:
P = $359
R = 8%
T = 9 years
Let us put all the values in the formula:
So, the interest accrued is $258.48.

The difference of four times a number and seven is 21. Find the number.
Answers
Answer:
7
Step-by-step explanation:
4x-7=21
4x=28
x=7.....
The number is 7.
We have a sentence - "The difference of four times a number and seven is 21".
We have to find the number.
Express the statement - "The difference of 40 and 20 is equal to n" in the form of expression.The expression representing the above statement is -
n = 40 - 20 = 20
According to the question, we have -
The difference of four times a number and seven is 21.
Assume the number be x.
Therefore -
4x - 7 = 21
4x = 28
x = 7
Hence, the number is 7.

Gas Station (2,7) -> y = [tex]\frac{1}{2}[/tex]x + 6 if you plug in the numbers it becomes 7 = 1 + 6
Grocery Store (6,3) -> x + 6y = 24 plug in the numbers it becomes 6 + 18 = 24
Bowling Ally (1, -3) -> 6x + 3y = -3 plug in numbers 6 -9 = -3
Movies (7, -7) -> y = -7 because the y coordinates for the movies = -7
Park(-2, -4) -> -6x + 2y = 4 plug in the numbers 12 - 8 = 4
Coffee Shop (-6, -8) -> -10x + 5y = 20 plug in the number 60 - 40 = 20
Gym (-8, -3)-> y = - [tex]\frac{1}{2}[/tex]x - 7 plug in the numbers -3 = 4-7
School (-6, 6) -> y = - [tex]\frac{1}{3}[/tex]x +4 plug in the numbers 6 = 2 + 4
6x + 3y = -3 quadrant II is (-x, y)
rearrange the equation:
3y = -6x - 3
y = -2x - 1
if x is -1, y will be 2 -1 = 1. So another solution for this equation is (-1, 1).

If you can buy 4 containers of pudding for $4.20 how much can you buy for $9.45 math problem PARAMETERS
*** 7 STEPS ***
Answers
Answer:
9 containers
Step-by-step explanation:
$4.20 for 4 containers
Form that we can find the cost per container, the unit cost.
$4.20 / 4 containers = $1.05/container
Each container costs $1.05
Now we find the number of containers we can buy with $9.45 by dividing $9.45 by the unit cost.
$9.45/($1.05/container) = 9 containers
Answer: 9 containers
Step-by-step explanation:
Four containers of pudding cost $4.20.
4x = 4.20
x = 1.05
Using this we know that one container of pudding costs $1.05.
Then, divide the maximum amount that you have by the cost of one.
9.45/1.05 = 9
With $9.45, you can buy nine cups of pudding.
In the case that you can buy the four containers in bulk (4 at a time)...
You can only buy 8 containers of pudding (two) because $4.20 only fits into $9.45 twice.

the remaining pages on Wednesday. On average she read
23 pages per day during these three days. How many pages
did she read on Wednesday?
Answers
Answer:
32
Step-by-step explanation:
Let Wed pages = x
(12 + 25 + x) / 3 = 23 Multiply both sides by 3
12 + 25 + x = 3 * 23 Combine the right
12 + 25 + x = 69
37 + x = 69 Subtract 37
x = 69 - 37
x = 32

D.y=- 1/5x

F.y=x
Answers
Answer:
D. y=-1/5(x)
Step-by-step explanation:
To find the equation of a line, use the formula y=mx+b, where x and y represent your x and y coordinates, m is your slope and b is your y-intercept.
b is you y-intercept, this is where the line cuts the y-axis. We can see from the graph that the line cuts the y-axis at (0,0), so c=0.
Now we have y=mx
Sub in one of our points (10,-2):
-2=m10
m=-1/5
So our equation looks like this:
y=-1/5(x)

Answer:
HM > CH
Step-by-step explanation:
You are correct, I didn't see the option HM > CH, which is correct, since the angle 90 degrees is larger than the angle 73, and then the sides opposite to them must follow suit.
Therefore, the correct answer is: HM > CH
The true statement from the triangles is (b) HM > CH

Next, we have
Angles at corresponding points = 90 degrees and 73 degrees
Since the angle 90 degrees is larger than the angle 73 degrees, and then the sides opposite to them must also have the same relationship
