Diameter of small pizza = diameter of large pizza divided by 2 = 9 inches
x = y divided by 2
x = 9 inches
Answer:
$162
Step-by-step explanation:
$1200 x .045 = $54 x 3 years = $162
Rearranging the first equation gives:
Substituting this into the other equation gives:
If x=-1:
So
x=-1, y=-5
Answer:
The answer is 450
Step-by-step explanation:
I got this equation:
x- the speed in which the turtle walks
5x+5(x+10)=4.5x+150+x*(150)/(x+10)
I got x=40, x=-50/11, but you can't have negative speed, so the turtle's speed is 40 meters per hour. After that, I just plugged in x onto one of the expressions and got 450.
