This formula only applies if the track is circular.  If it is, then we write the equation:

2*r*pi=400

Dividing by 2pi, we see that:

r=200/pi

This is approximately 63.66.

An ice cream sundae costs $1.75 plus an additional $0.35 for each topping. If the total
laiz [17]

Answer:

3

Step-by-step explanation:

$1.75 (ice cream) + $0.35 (topping) * x (some toppings) = $2.80, so I can rewrite it like that: 1.75+0.35x=2.80

1) Move the constant to the right side and change its sign: 0.35x=2.8-1.75

2) Substract the numbers: 0.35x=1.05

3) Divide the both sides of the equation by 0.35

4) x=3

sveticcg [70]

Answer:

3/5 y   +9/10 z

Step-by-step explanation:

4/5 y + 7/10 z - 1/5 y + 1/5 z

4/5 y - 1/5 y + 7/10 z + 1/5 z

We need to get a common denominator for the z term of 10

4/5 y - 1/5 y + 7/10 z + 1/5 *2/2 z

4/5 y - 1/5 y + 7/10 z + 2/10 z

3/5 y   +9/10 z
