2m+(m-15)=90 solve for m

Ronch [10]

Answer:

m = 35

Step-by-step explanation:

2m + m -15 = 90

3m -15 = 90

+15 +15

3m = 105

/3 /3

m = 35

To check the work just insert 35 for m:

2(35) + 35 -15 = 90

70 + 35 -15 = 90

105 - 15 = 90

90 = 90

If the ratio of the triangular pyramids' surface areas is 4:9, what is F?

VladimirAG [237]

Answer:

The answer to your question is f = 10.35 in

Step-by-step explanation:

Data

Proportion = 4:9

height 1 = 4.6 in

height 2 = f

Process

1.- Write the proportion

$\frac{4}{4.5} = \frac{9}{f}$

2.- Solve for f

$f(\frac{4}{4.6}) = f(\frac{9}{f})$

$f(\frac{4}{4.6}) = 9$

$4.6\frac{4f}{4.6} = 9(4.6)$

4f = 41.4

$\frac{4f}{4} = \frac{41.4}{4}$

f = 10.35 in

A carpenter wants to cut a 45 inch board into two pieces such that the longer piece will be 7 inches longer than the shorter how

matrenka [14]

Answer:

19 in and 26 in

Step-by-step explanation:

Let the length of the shorter piece be x

Then the longer piece is x + 7

x + x + 7 = 45
2x = 45 - 7
2x = 38
x = 19

Short piece = 19 in

Long piece = 26 in
