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.
Frank believes his bedroom wall measures 12 feet long.
He has a ruler that is 1? feet long.
He uses this ruler to measure his bedroom wall.
Which equation can be used to solve for T,
the number of times he will have to use the ruler to check the length of his bedroom wall?
A. 1? = 12T
B. 1? T = 12
C. 1? + T = 12
D. T – 1? = 12
Answer:
A
Step-by-step explanation:
Answer:
B. 1? T = 12
Step-by-step explanation:
Since the bedroom measures 12 feet long, the answer or the product should be 12 (12 only)
He uses “1?” to measure the bedroom, and we need to know HOW MUCH TIMES he uses it.
So, 1? T will be the equation since we need to know how much times he uses the ruler.

For the first equation 6v+38≤ -4
The answer would be v≤-7
and for the second equation 2(v+3)≥-2
the answer would be v≥-4
Step-by-step explanation:
6v+38≤ -4
Subtract 38 from both sides
6v+38-38≤-4-38
Simplify
6v≤-42
Divide both sides by 6
6v/6≤-42/6
Simplify
v≤-7
SAME THING FOR THE OTHER
2(v+3)≥-2
Divide both sides by 2
2(v+3)/2≥-2/2
Simplify
v+3≥-1
Subtract 3 from both sides
v+3-3≥-1-3
And finally, simplify
v≥-4

For the past three months, Grace used her cell phone for 43 minutes, 62 minutes, and 57 minutes. How many minutes would she have to use her cell phone this month for the average usage over the four months to be 55 minutes? Be sure to include units in your answer
Answer:
Step-by-step explanation:
If they want the average for four months to be 55 minutes, this means that the total of the four months = 55 x 4
Total of four months = 220 minutes
They already told us that the three previous months she used her cellphone for 43 minutes, 62 minutes and 57 minutes.
All you have to do now is subtract everything from the total of the four months.
4th month = 220 - 43 - 62 - 57
= ? Minutes
One number is 14 more than another number. Their sum is 58. Find the numbers.
Numbers are 36, 22
What is an equation?An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in mathematics when you do not know the exact number in a calculation.
Given
One number is 14 more than another and their sum is 58.
Let one number be x
Another number will be x + 14
Rewriting the equation in mathematical form
⇒ [tex]n+ (n+4) =58[/tex]
⇒ [tex]2n +14 =58[/tex]
⇒ [tex]2n = 58-14[/tex]
⇒ [tex]2n=44[/tex]
⇒ [tex]n= \frac{44}{2}[/tex]
⇒ [tex]n=22[/tex]
⇒ [tex]n+14=22+14=36[/tex]
Hence, numbers are 36, 22

Find value of y!
Step-by-step explanation:
9x+21=11x-1 (corresponding angle)
-2x=-22
x=11
11x-1+5y-5=180
11*11+5y-6=180
121+5y-6=18
5y+115=180
5y=180-115
5y=65
y=13
1... 2(9n-1)+7(n+6)=-60
2... 11(4-6y)+5(13y+1)=9
Step-by-step explanation:
2(9n-1)+7(n+6)=-60
18n - 9 + 7n + 42 = -60
25n + 33 = -60
25n = -93
n = -3.72
11(4-6y)+5(13y+1)=9
44 - 66y + 65y + 5 = 9
-y + 49 = 9
-y = -40
y = 40
Answer:
Hello! I hope I’m correct!! :)
1. n = -4
2. y = 40
Step-by-step explanation:
Steps for the first equation.
Step #1. {we are solving for “2(9n-1)+7(n+6)=-60”}
[tex]18n-2+7n+42=-60[/tex]
Step #2. Simplify.
[tex]25n+40=-60[/tex]
Step #3. Subtract 40 {from both sides}
[tex]25n=-60-40[/tex]
Step #4. Simplify.
[tex]25n=-100[/tex]
Step #5. Divide both of the sides by 25. Which will be:
[tex]-\frac{100}{25}[/tex]
Step #6. Now divide (simplify) 100 & 25 which will give you the answer.
[tex]n=-4[/tex]
So for the first equation the answer is n = -4______________________________________
Now let’s solve the second equation.
Step #1. Expand
[tex]-y+49=9[/tex]
Step #2. Subtract 49 from both sides.
[tex]-y+49-49=9-49[/tex]
Step #3. Simplify.
[tex]-y=-40[/tex]
Step #4. Divide both sides by -1.
[tex]-40/-1[/tex]
Step #5. Simplify.
[tex]y=40[/tex]
And your answer to the second equation would be y = 40Sorry if this is incorrect but I hope this helps! If you have any questions about this, feel free to ask! Have a wonderful day! (≧∇≦)

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
