1 / 7.15 = 1000 / x......$ 1 to 7.15 rand = $ 1000 to x rand
cross multiply because this is a proportion
(1)(x) = (7.15)(1000)
x = 7150 <=== Sophia got 7150 rand
<span>The volume of a rectangular prism = its base area * height
substitute:
</span>
x3 – 3x2 + 5x – 3 =<span> (x2 – 2) * h
h=</span> (x3 – 3x2 + 5x – 3)/<span>(x2 – 2)
so you can use the long division</span>
X= - 1/5
Y=5x+1
0=5x+1
-5x=1
-1/5
