Complete Question

Kiran buys supplies for the school’s greenhouse. He buys bags of fertilizer and packages of soil. He pays $5 for each bag of fertilizer and $2 for each package of soil, and spends a total of $90. The equation 5f + 2p = 90 describes this relationship.

If Kiran solves the equation for p, which equation would result?

A. 2p = 90 − 5f

B. p = 5f − 90 /2

C. p = 45 − 2.5f

D. p = 85 f /2

A. 2p = 90 − 5f

Step-by-step explanation:

The equation 5f + 2p = 90 describes this relationship.

We are to solve for p, this means to make p the subject of the formula , hence:

5f + 2p = 90

Subtract 5f from both sides.

5f - 5f + 2p = 90 - 5f

2p = 90 - 5f

Divide both side by 2

2p/2 = 90 - 5f/2

p = 90 - 5f/ 2

If Kiran solves the equation for p, the equation that would result is

2p = 90 − 5f .

Further simplified to :

p = 90 - 5f/ 2

Option A is correct.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
