The answer to this would be 5x+6>=21. Just wanted points :P
2x+9=6x+7. 2x+2=6x. 2=4x. X=1/2 a year
1/6 because the only way the sum can be less than 4 if the first die is a 2 is if the second die is a 1.

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
Answer:
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.
