Answer:

-2.33

Step-by-step explanation:

Let the number be denoted as "x"

-45x + 12 = 117

-45x = 117-12

-45x = 105

x = 105/-45

x= -2.33

The formula d = 26t + 32.5 can be used to find the distance (d) between two cars after traveling (t) hours in opposite direction

Sindrei [870]

Answer:

Step-by-step explanation:

The formula given is:

$d=26t+32.5$

Where

d is the distance between two cars

and

t is the time it takes

We want the time it takes (so we need t) for the cars to be 117 miles apart (this is the distance). Thus, it means:

d = 117

t = ???

We plug in 117 into d and solve the equation for t. Shown below:

$d=26t+32.5\\117=26t+32.5\\117-32.5=26t\\84.5=26t\\t=\frac{84.5}{26}\\t=3.25$

So, it takes 3.25 hours
