a. 6×1.25=x 6×1.333=x 6×1.5=x 6×1.75=x 6×2=x make sense?
b. 6×.666=x
c. by definition a cube has equal length sides in all 3 dimensions.

Plz help me -5(y+2)<60

kkurt [141]

Answer:

y > -14

Step-by-step explanation:

-5(y+2) < 60

-5y - 10 < 60 (Expand the term on the left)

-5y < 70 (Bring the numbers to the right)

y > -14 (Divide both sides by -5. Note that the inequality sign changes as we are dividing by a negative number)
