Step-by-step explanation:
hmmm this is messy
Alicia : y = 43 x
For x = 1 ( 1 hour ):
y = 43 miles, v = 43 mph
Trish: 69 = v * 1.5
v = 69 : 1.5
v = 46 mph
Alicia: 43 mph
Trish: 46 mph
The woman who drives at a slower rate is : A ( Alicia )
Looks like a paper from dublin the answer is :
d=-60h+120 First Part
d=-60h+160
Hey there!
When we solve for x, we need to isolate x on one side.
This is just a one-step equation, meaning there is only one thing we need to do to solve for x, or isolate x.
Starting with 87 + x = 100:
Subtract 87 from each side.
87 <u>- 87</u> + x = 100 <u>- 87</u>
Simplify. Subtracting 87 from 87 makes it equal to 0.
x = 13
Your answer is A. 13.
Hope this helps!
