Answer:
Style A shoes sold : <u>152</u>
Style B shoes sold : <u>88</u>
Step-by-step explanation:
Let :
- Style A shoes = x
- Style B shoes = y
Forming equations :
- x = 2y - 24
- 66.95x + 84.95y = 17,652
Substitute the value of x from 1 in 2.
- 66.95 (2y - 24) + 84.95y = 17,652
- 133.90y - 1606.80 + 84.95y = 17,652
- 218.85y = 19258.80
- <u>y = 88</u>
<u />
Finding x :
- x = 2(88) - 24
- x = 176 - 24
- <u>x = 152</u>
<u />
Solution :
- Style A shoes sold : <u>152</u>
- Style B shoes sold : <u>88</u>
20/4 = 15/x
20x = 60
x = 3 feet
choice (1.) is the answer
Put y in the x+2y-6. x+2(3x-7)=0. So x+6x-14=0. 7x-14=0. 7x=14. x=2
Don’t kill you self because it’s not that serious okay? Also I have no idea what this is
Quadratic eq standard form is
Ax^2+bx+c=0
<span>a, b and c are known values.
a can't be 0.</span><span>"x" is the variable
lets take an example
</span><span>x^2 − 4x+2 = 0
</span><span>
x^2-2x-2x+2=0
x(x-2) - 1(x-2)=0
x=1,2
