Jesse bought 5.2 pounds of pears for $6.50. Find the unit rate. How much would 4 pounds of grapes cost?

Step-by-step explanation:

5.2/6.5=4/x ; x=?

5.2x/6.5=4

5.2x=4×6.5

x=26/5.2

x=5

4 pounds of grapes cost 5 dollars.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
