Answer:
So first, there is an acronym for the strategy, KFC.
°π°
Keep the first fraction. Ex, 4/5 ÷ 1/5
Flip the second fraction. Ex, 4/5 ÷ 5/1
Change symbol. Ex, 4/5 ÷ 5/1 turns into 4/5<em>x</em>5/1
The answer is (14) just add them all up
1. a
2. you need to give the indivisual heights of the (compound) shape
OK the next step is to multiply 3r -1 by -7r
this gives us -21r^2 + 7r and we write it below -21r^2 + 25r
and subtract
This gives us 18r and we bring down the -6 to give
18r - 6
Finally we divide 18r by -3r to give -6 then add - 6 to the r^2 - 7r on the top
then multiply -3r - 1 by -6 to give 18r - 6
subtraction then leaves nothing.
so the answer is r^2 - 7r - 6
Answer:
When x = 12, y = 4.
Step-by-step explanation:
If
y
∝
x
we can write that
y
=
k
⋅
x
where k is a constant of proportionality.
Using the values given:
6
=
18
⋅
k
⇒
k
=
1
3
y
=
1
3
⋅
12
=
4
