choli [55]

Answer:

b=15

How I got it:

32 + (7x4) = 32 + 28 = 60

60 divided by 4 = 15

Checking:

15 - 7 = 8

8 x 4 = 32

32 = 32

<em>You can tell b = 15 is the correct answer.</em>

Lerok [7]

Answer:


12 million dollars.


Step-by-step explanation:


Let the sales in the first year be x million .

So the sales in the second year were x + 4 million, in the third year were 3(x + 4) and this is 48 million dollars.

So we have the equation 3(x + 4) = 48

3x + 12 = 48

3x = 36

x = 12 million dollars.

On a blueprint, the scale says that 2 cm represents 3 m. What is the actual length of a wall if its measurement on the blueprint
Leokris [45]

Answer:

The actual length of the wall is 10.5 m

Step-by-step explanation:

Write and solve an equation of ratios to answer this question:

2 cm       3 m

--------- = ---------

7 cm         L

Solve this for L by inverting both sides:  

 7cm          L

---------- = --------

  2 cm      3 m

and then multiplying both sides by 3m:

21

----- = L

 2

The actual length of the wall is 10.5 m
