Answer: 137.5 miles

Step-by-step explanation:

From the question, we are told that a map was created using the scale 1 inch:

25 miles. We are told to find the length in miles if the river is 5.5inches long on the map.

Since we have been given on the question that 1 inch:25 miles, to get 5.5 inches in miles, we need to multiply 5.5 by 25miles. This will be:

= 5.5 × 25 miles

= 137.5 miles.

Answer:

20/5 = x /4 x = 80/5 = 16

x - 10 / 39 = 5/15 = 1/3

3x - 30 = 39

3x = 69

x = 23

(2x + 10 ) * 4 = 10 *(x + 3)

8x + 40 = 10x + 30

2x = 10

x = 4.

AE = 2(5) + 10 = 20, hope this helped.

Same case as Pablo's, more or less.

a = price for the desktop

b = price for the laptop

we know the laptop is 150 bucks more than the desktop,  b = a + 150.

how much is 7% of a?  (7/100) * a, 0.07a.

how much is 9.5% of b?  (9.5/100) * b, 0.095b.

total interests for the financing add up to 303, 0.07a + 0.095b = 303.

\bf \begin{cases}&#10;\boxed{b}=a+150\\&#10;0.07a+0.095b=303\\&#10;----------\\&#10;0.07a+0.095\left(\boxed{a+150}  \right)=303&#10;\end{cases}&#10;\\\\\\&#10;0.07a+0.095a+14.25=303\implies 0.165a=288.75&#10;\\\\\\&#10;a=\cfrac{288.75}{0.165}\implies a=1750

how much was it for the laptop?  well b = a + 150.
