Answer:
Champs is 64.8, Footlocker is 64. Footlocker is selling them for cheaper. You would go to Footlocker, as it's .8 off.
You can set up this equation as:

Because remember, 70% is equal to 0.7 and x represents the unknown value. So, let's just solve it:

So,
70% of 120 is 84.
Answer:

Step-by-step explanation:
This is Isosceles triangle (look at the picture).
We know:
All triangles have internal angles that add up to 180°
Therefore:

combine like terms:

(x - 2)° and 3y° are supplementary angle (Two Angles are Supplementary when they add up to 180°).
Therefore:

substitute x = 29 and solve for y:

290 * 7 = 1400 + 630 = 2,030
2030 - 7 = 2,023
