Answer:
A.
Step-by-step explanation:
It's literally the same equation written in reverse, which according to the commutative property, can be done.
Answer: A
Step-by-step explanation:
For this problem, we know that A is the correct answer. A is the same as the given expression because it is the same, but the order is switched. When you multiply both of them, you would get the same answer.
We can eliminate B because [tex]\frac{2}{5}[/tex] should be positive, not negative.
We can eliminate C because the fraction should be [tex]\frac{2}{5}[/tex], not [tex]\frac{5}{2}[/tex].
We can eliminate D because (-1×-7) given you 7, not -7.
Therefore, A is the right answer.

Solve the equations in Parts A and B using inverse operations. Check your solutions. In your final answer, include all of your work.
Part A: 5 + x^2 = 2x^2 + 13
Part B: 5 + x^3 = 2x^3 + 13
Answer:
x = - 2√2
x = -2
Step-by-step explanation:
A . 5 + x² = 2 x² +13
5 + x² - 2 x² - 13 = 0
- x² -8 = 0
- x² = 8
x² = -8
x = - √8
x = - 2√2
B . 5 + x³ = 2 x³ + 13
5 + x³- 2 x³ - 13 = 0
- x³ -8 = 0
-x³ = 8
x³ = -8
x = - ∛8
x = -2

A radio station is giving away a $100 bill to every 30th caller and movie tickets to every 10th caller. If there are 120 callers, how many callers will get both the $100 and the movie tickets?
Answer:
4 callers
Step-by-step explanation:
Because 10 is a factor of 30, we don't have to worry about it. Every 30th caller will get both rewards. 120/30=4 so the answer is 4.
The water level of a lake fell by 1 1/2 inches during a 1 2/3-week-long dry spell. Find the average rate at which the water level changed every week.
Answer: The average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
Step-by-step explanation:
Given: Change in water level in [tex]1 \dfrac23[/tex] week = [tex]-1\dfrac12[/tex] inches = [tex]-\dfrac32[/tex] icnhes
To find : The average rate at which the water level changed every week.
i.e. Change in water level per week.
As [tex]1\dfrac23 = \dfrac52[/tex]
Change in water level in 1 week = [tex]-\dfrac{3}{2}\div\dfrac52 = -\dfrac32\times \dfrac25= -\dfrac35[/tex]
Hence, the average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
We want to find the average rate of change at which the water level changed in a given time period.
We will find that the average rate of change is:
[tex]r = - 0.9 in/week[/tex]
We define the average rate of change as the quotient between the total change and the time it takes.
Here we have:
total change = -(1 + 1/2) in
Time = (1 + 2/3) weeks
Then the average rate of change is:
[tex]r = \frac{-(1 + 1/2) in}{(1 + 2/3) weeks} = - 0.9 in/week[/tex]
This means that the water level decreases, in average, 0.9 inches per week.

7x^2– 19x – 6
How do I factorize this expression?
Answer:
x = 3 and x = -2/7
Step-by-step explanation:
you can multiple -6 by 7 = -42
and then find what adds into -19 but can multiply together to get -42.
In this case (x-21)(x+2) would work
then you have to divide out your 7 from both numbers,
(x-21/7)(x+2/7)
then you have to make them equal to zero
x-21/7 = 0 = x = 21/7 = 3
x+2/7 = 0 = x = -2/7
so your final answer is x = 3 and x = -2/7

Karrisa is going water skiing. She has a choice on either renting or purchasing the skis. She must also rent a safety jacket. She can purchase skis for $125 a pair. The rental fee for skis and a safety jacket is $30 per hour. The rental fee for only the safety jacket is $5 per hour. How many hours must she ski for the price of renting skis and purchasing the skis to be the same?
Answer:
5 hours
Step-by-step explanation:
The rental option for h hours costs ...
r = 30h
The purchase option for h hours costs ...
p = 125 +5h
These costs are the same when ...
r = p
30h = 125 +5h
25h = 125 . . . . . subtract 5h
h = 5 . . . . . . . . . divide by 25
Karrisa must ski for 5 hours for the prices to be the same.

3(x-4)= 36
Answer:
x = 16
Step-by-step explanation:
3(x-4)=36
First we will distribute:
3x - 12 = 36
Add 12 to both sides:
3x = 48
Divide both sides by the coefficient:
x = 16
Check your work:
3 (x - 4) = 36
3 (16 - 4) = 36
3 (12) = 36
36 = 36
Final answer:
x = 16

Step-by-step explanation:
Evaluating expressions involve solving and simplifying the expression
The result of [tex]\mathbf{-12 - 27}[/tex] is -39The result of [tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2)}[/tex] is 9.4The expressions are given as:
[tex]\mathbf{(a)\ -12 - 27}[/tex]
[tex]\mathbf{(b)\ 8 + 53 * 0.4 - ( 23-3.2)}[/tex]
[tex]\mathbf{(a)\ -12 - 27}[/tex]
Subtract 27 from -12
[tex]\mathbf{-12 - 27 = -39}[/tex]
Hence, the result of [tex]\mathbf{-12 - 27}[/tex] is -39
[tex]\mathbf{(b)\ 8 + 53 * 0.4 - ( 23-3.2)}[/tex]
Start by evaluating the expression in brackets
[tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2) = 8 + 53 * 0.4 - 19.8}[/tex]
Evaluate the products
[tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2) = 8 + 21.2 - 19.8}[/tex]
Add and subtract
[tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2) = 9.4}[/tex]
Hence, the result of [tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2)}[/tex] is 9.4
