Answer:

x = ± 4/5

Step-by-step explanation:

25 x^2 = 16

Divide each side by 25

25 x^2 /25 = 16 /25

x^2 = 16 /25

Take the square root of each side

sqrt(x^2) = ±sqrt(16/25)

We know that sqrt(a/b) = sqrt(a)/ sqrt(b)

x = ±sqrt(16) / sqrt(25)

x = ± 4/5

At a strawberry stand Luisa paid $4.50 for 2 pounds of strawberries. How much would you expect to pay for five pounds or strawbe

Daniel [21]

Half of 4.50 is 2.25, so for one pound it would be $2.25.

To calculate five pounds, you need to add 2.25+2.25+2.25+2.25+2.25 = 11.25.

For five pounds of strawberry's, it would cost $11.25.

Hope this helped !
