Over the summer , mr. patel refilled a bird feeder 24 times using 6 cups of seed each time. a bag of seed holds 32 cups. how many bags of seed did mr. patel use?

4.5 bags

Step- by- step explanation:

If each time, Mr. Patel uses 6 cups

Then, the number of cups used for the 24 times

Now,

32 cups:1 bag

144 cups:x bags

This implies that 144 cups equals 4.5 bags

Therefore Mr. Patel uses 4.5 bags of seed.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
