Explanation:
Because we're given multiple choices to pick from, we can go through each to do trial and error.
For instance, if v = 52, then
v/13 < -7
52/13 < -7
4 < -7
but that's a false statement since 4 is not smaller than -7. Use a number line to see this. You should have -7 to the left of 4, showing that -7 is the smaller value.
Because 4 < -7 is false, this means v/13 < -7 is false when v = 52. This rules out v = 52. You should find that v = 26 and v = -39 won't work for similar reasons.
Only v = -130 works since...
v/13 < -7
-130/13 < -7
-10 < -7
This is true because -10 is to the left of -7 on the number line.
-------------------------------------------------
Another approach:
We have some unknown number v, and we're dividing by 13 to get the expression v/13. To undo this, we multiply both sides by 13
v/13 < -7
13*(v/13) < 13*(-7) .... multiply both sides by 13
v < -91
So any solution to the original inequality must be smaller than -91. This allows us to rule out v = 52, v = 26 and v = -39.
The value v = -130 is smaller than -91, so it satisfies v < -91. Therefore, v = -130 is a solution to the original inequality.

Nellie took a total of 27 quizzes over the course of 3 weeks. After attending 4 weeks of school this quarter, how many quizzes will Nellie have taken in total?
Answer:
The answer is 36
Step-by-step explanation:
If you do 27÷3 you get 9. So if it's 4 weeks you just add 9 which is 36
Answer:
36
Step-by-step explanation:
First, we need to know how many quizzes she takes in 1 week.
27 /3 = 9
So, what is missing here is the number of quizzes is 4 weeks, so we will multiply 4 x 9.
4 x 9 = 36

Answer:
3 and 6 and 24 top to bottom
Step-by-step explanation:
For the middle 18 divided by 6 is 3 so therefore you have to multiply 3 to 2 to get the answer for the first one. For the bottom one you have to do 8/2 and that equals 4 so you multiply 6 by 4 and 4 times 6 is 24, and the for the first one it’s pretty straight forward just divide the second column in half

Pythagoras' Theorem -
Answer:
[tex]a = 9.4[/tex]
[tex]b = 12.0[/tex]
Step-by-step explanation:
Given
See attachment
Required
Determine the values of a and b
To solve for a, we consider the first triangle.
Using Pythagoras:
[tex]a^2 = 8^2 + 5^2[/tex]
[tex]a^2 = 64 + 25[/tex]
[tex]a^2 = 89[/tex]
Take square root of both sides
[tex]a = \sqrt{89[/tex]
[tex]a = 9.4[/tex] -- approximated
To solve for b, we consider the second triangle.
Using Pythagoras:
[tex]17^2 = 12^2 + b^2[/tex]
[tex]289 = 144 + b^2[/tex]
Collect Like Terms
[tex]b^2 = 289 - 144[/tex]
[tex]b^2 = 145[/tex]
Take square root of both sides
[tex]b = \sqrt{145[/tex]
[tex]b = 12.0[/tex] --- approximated
Find the principal of interest!! random answers will be reported
1. Interest: $640
Rate: 4%
Time: 1 year
2. Interest: $2,016
Rate: 12%
Time: 3 years
Answer:
4: $16,000
5: $4978.66
6: .086278 or 8.62%
Step-by-step explanation:
For the entirety of this problem I am going to assume that the interest is compounding annually
4: to find the interest earned in a period you have the following equation
(principle*(1+i)^n)-Principle
We can plug in the values we know
principle=p
(p*1.04)-p=640
This means that p=640/.04
p=16000
5: This is the same deal as the other one
2016=(p*(1.12)^3)-p
Solve this and get 1.404928p-p=2016
This means that .404928p=2016
Which means that p=4978.66
6: This one is slightly different but we can still use the same formula
720=4000((1+i)^2)-4000
We can add 4000 and then divide by 4000 to get
1.18=(1+i)^2
Take the square root of both sides and subtract 1 to solve for i
i= .086278 or 8.62%
Answer:
1. Interest: $640
Rate: 4%
Time: 1 year
2. Interest: $2,016
Rate: 12%
Time: 3 years

Victor bought a handbag that was marked down 60% from an original price of $50. If he paid 15% sales tax, what was the total cost of the handbag
Answer:
$23
Step-by-step explanation:
first you find 60% of 50
50 x .6 = 30
then you subtract 30 from 50
30 - 50 = 20
since they paid $20 for the hand bag we need to find 15% of 20
20 x 0.15 = 3
finally we add 20 and 3
20 + 3 = 23
