-2r+8

The first step is to combine like terms. These would be 4r, -7r, and r since they have the same variable. This gives you -2r. Since there are no other like terms to combine, you end up with -2r+8

andre [41]

Answer:

The distance from Gary's school to  the BART station is 564 yards

Step-by-step explanation:

Let

x ----> the distance  from Gary's school to the corner market

y ----> the distance from Gary's school to  the BART station

we have

x=47\ yd

we know that

To find out the distance from Gary's school to  the BART station, multiply the distance from Gary's school to the corner market by 12

so

y=12x

substitute the value of x

y=12(47)=564\ yd

therefore

The distance from Gary's school to  the BART station is 564 yards

If f(1) = 7 and f(n) = 5f (n − 1) then find the value of f(5).
nevsk [136]

Answer:

f(5) = 4375

Step-by-step explanation:

Given f(n) = 5f(n - 1) and f(1) = 7

This allows us to find the next term in the sequence from the previous term

f(2) = 5f(1) = 5 × 7 = 35

f(3) = 5f(2) = 5 × 35 = 175

f(4) = 5f(3) = 5 × 175 = 875

f(5) = 5f(4) = 5 × 875 = 4375
