Answer:

425 miles

Step-by-step explanation:

If it travels for a longer time, it will cover more miles.

You can therefore treat this as direct proportion without having to find the actual speed of the train. It is enough to know that it will travel at the same speed.

255/3 = x/5

85 = x/5

x = 425

Can you help me? <br><br> 4+3(x+5)=5x-7

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

4 + 3(x + 5)=5 x - 7

3x + 19=5x - 7

3x + 19 - 19=5x - 7 - 19

3x =5x - 26

3x - 5x=5x - 26 - 5x

-2= -26

-2x/-2 = -26/-2

x= 13

It might be wrong. I may have made a mistake with typing sorry.

Hope this helps a bit.

Write an exponential function to model the following situation

Dominik [7]

Answer:

$y = 140000(1.04)^{x}$ ; 262 000

Step-by-step explanation:

The general formula for an exponential function is

$y = a(b)^{x}$

a = 140 000; b = 1.04; x = 16

$y = 140000(1.04)^{x}$

y = 140 000(1.04)¹⁶

y = 140 000 × 1.873

y = 262 000

The graph below shows the population growth over time.
