Answer:
Step-by-step explanation:
a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying. Ex
3
(2)(9)
x
=
18
3
=
6
x=
3
18
=6
If I have to , I'll include my fractional equation with the arrows. answer is:
x = 6
2800 ÷ 400
Cross out 2 zeros from both numbers, then you have 28 ÷ 4 = 7
Answer:
48 π
Step-by-step explanation:
Area of Circle =πr∧2
Big Circle Area = π(8)∧2 = 64π
Small Circle Area =π(4)∧2= 16π
Shaded Region = 64π - 16π = 48π
(if 2 is a square)
6xy ( x2 - xy + y2)
= 6x3y - 6x2y2 - 6xy3 --------------the threes and twos on this line are squares and cubics. the six is just a whole number
