Step-by-step explanation:
(don't worry I guessed and got it correct)
Direct variation always has the relationship y=kx. Indirect inverse variation always has the relationship y=k/x.
In this case y=kx, where k=6, so this is a direct variation.
-5(x-4)=-30
-5x - -20=-30
-5x+20=-30
-20 -20
-5x=-50
divide both sides by -5
x=10
Answer:
32600000
Step-by-step explanation:
= 3.26 × 107
(scientific notation)
= 3.26e7
(scientific e notation)
= 32.6 × 106
(engineering notation)
(million; prefix mega- (M))
= 32600000
(real number)
Since 80 divided by 22 is 3.636, the ratio is 3.636:1
