Answer:
2,800 CUV cars were sold
Step-by-step explanation:
7 out of 10 are CUV
Total sold are 4,000
Set them equal to each other:
Cross multiply:
Solve for x:
x = 2,800
<span>Simplifying
(2x + -7y ) = 0
Multiply
(2x + -7y) * (x + y) </span><span>
(2x * (x + y) + -7y * (</span><span>x + y)) = 0
</span>((x * 2x + y * 2x) + -7y * (x + y)) = 0<span>
</span>Reorder the terms:
((2xy + 2x2) + -7y * (x + y)) = 0
((2xy + 2x2) + -7y * (x + y)) = 0
(2xy + 2x2 + (x * -7y + y * -7y)) = 0
(2xy + 2x2 + (-7xy + -7y2)) = 0<span>
Reorder the terms:
(2xy + -7xy + 2x2 + -7y2) = 0
</span>
<span>Combine like terms: 2xy + -7xy = -5xy
(-5xy + 2x2 + -7y2) = 0
</span>Solving -5xy + 2x2 + -7y2 = 0<span>
Solving for variable 'x'.
Factor a trinomial.
(2x + -7y)(x + y) = 0

Answer:
2.875
Step-by-step explanation:
you have to change them into decimals. so 5 3/4 would be 5.75 and 2 7/8 would be 2.875. once you do that you can subtract
