Select all of the answers that apply.Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m?

-15m = -4m
-7m - 8 = m - 4
-3m - 8 = 4 - m
m - 4 = -7m - 8
-8 - 7m = -4 + m
-8 - 3m = 4 - m

Answers

Answer 1
Answer: first  you need to solve the equation
-2m-5m-8=3+(-7)+m
-7m-8=-4+m   or -7m-8=m-4
the second choice

also this choice
8 - 7m = -4 + m  the fifth one
Answer 2
Answer:

To solve this problem, we must simplify the the equation:

Here is the base equation -2m - 5m - 8 = 3 + (-7) + m (Add all like terms):


#1 -2m - 5m - 8 = 3 + (-7) + m (Property of Addition)

#2 -7m - 8 = -4 + m (Most Simplified Equation)


The answer your would be the 2nd one. -7m - 8 = m - 4

13 is 26% of what number

Answers

Steps:
1. Do a proportion
13/x times 26/100
2. Do 13 times 100 which equals 1300
3. Do 1300 divided by 26
4. Your answer is 50%

13 is 26 percent of 50.

To determine the number that 13 is 26% of, we can set up the equation:

13 = 0.26x

Here, x represents the unknown number we are trying to find. To solve for x, we divide both sides of the equation by 0.26:

13 / 0.26 = x

Simplifying the expression, we have:

x = 50

Therefore, 13 is 26% of 50.

To understand this calculation, we recognize that 26% can be expressed as the decimal 0.26. Multiplying 0.26 by the unknown number x gives us 13, which means that 13 is 26% of x. By dividing both sides of the equation by 0.26, we isolate x and find that it is equal to 50.

during unusual cold weather the temperature in Miami Beach was 10 this was 12 degrees more than in tallahassee what is the temperature in tallahassee

Answers

Miami Beach = 10°

This was 12° more than in Tallahassee.

Miami, 10° = 12° + Tallahassee

10° = 12° + T

10° - 12° = T

-2° = T

Temperature in Tallahassee is -2°
-2 degrees in Tallahassee 

10-12=-2 

The length of a rectangle is 5cm longer than twice the length of the width. If the perimeter is 88 centimeters, what is the width?

Answers

L = length
W = width
P = perimeter

Equations:
L = 2W + 5
2L + 2W = P
P = 88

Solve using the equations above:

2(2W + 5) + 2W = 88
4W+ 10 + 2W = 88
6W + 10 = 88
6W = 78
w=16

the width is 16 centimeters
