<span>2m/7+3m/14=1

We simplify the equation to the form, which is simple to understand
<span>2m/7+3m/14=1

Simplifying:
<span> + 0.285714285714m+3m/14=1

Simplifying:
<span> + 0.285714285714m + 0.214285714286m=1

We move all terms containing m to the left and all other terms to the right.
<span> + 0.285714285714m + 0.214285714286m=+1

We simplify left and right side of the equation.
<span> + 0.5m=+1

We divide both sides of the equation by 0.5 to get m.
<span>m=2

4: (3/4 - 1/2) X 3/5. 

You need them all to have the same denominator (bottom number) 
The lowest common denominator (LCM) of 2,4 and 5 is 20
4 X 5 = 20
2 X 10 = 20
5 X 4 = 20 

Then multiply the top number by the amount you need to multiply the bottom number by to get 20

3 X 5 = 15
1 X 10 = 10
3 X 4 = 12

(3/4 - 1/2) X 3/5. Turns to (15/20 - 10/20) X 12/20.

15 - 10  = 5
5 X 12 = 60

Answer: 60/20
Simplified: Either 3 or 3/1.



If you use the steps above then you should be able to do the rest :D

Equation: w = 112 + 8t Which input results in an output of 176? What is the output in the ordered pair (4, 144)?
Grace [21]

Answer:

  • 8
  • 144

Step-by-step explanation:

Generally, the single variable on the left side of the equation is the "output" or dependent variable, while any other variables on the right side of the equation are considered to be independent variables, or "input."

So, we assume your first question is asking for the value of t that makes w=176. Put the values in the equation and solve for the unknown.

  w = 112 +8t

  176 = 112 + 8t

  64 = 8t . . . . . . . subtract 112

  8 = t . . . . . . . . . divide by 8

The input for an output of 176 is 8.

__

Ordered pairs are always written as ...

  (input, output)

So, (4, 144) means the output is 144 for an input of 4.
