Solve this equation:
X – 8
6
= 4.5
Your answer

x=35

Step-by-step explanation:

To solve this equation:

(x-8)/6=4.5

We have to find out what x is, by getting x by itself. Perform the inverse operation to the equation. Remember to perform everything to both sides.

6 is being divided by x-8. The inverse of division is multiplication. Multiply both sides by 6.

(x-8)/6*6=4.5*6

(x-8)= 4.5*6

x-8=27

8 is being subtracted from x. The inverse of subtraction is addition. Add 8 to both sides.

x-8+8=27+8

x=35

Let’s check out solution. Plug 35 back in for x in the original equation.

(x-8)/6=4.5

(35-8)/6=4.5

27/6=4.5

4.5=4.5

Both sides of the equation are the same, so we know our solution of x=35 is correct.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
