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.
34x+95=3(14x+9)
We move all terms to the left:
34x+95-(3(14x+9))=0
We calculate terms in parentheses: -(3(14x+9)), so:
3(14x+9)
We multiply parentheses
42x+27
Back to the equation:
-(42x+27)
We get rid of parentheses
34x-42x-27+95=0
We add all the numbers together, and all the variables
-8x+68=0
We move all terms containing x to the left, all other terms to the right
-8x=-68
x=-68/-8
x=8+1/2

Answer:
(x - 5)(x - 3)
Step-by-step explanation:
You need two numbers that multiply to 15 and add to 8. There aren't many numbers that will do that.
15 and 1 is one pair of numbers. They multiply to 15 but don't add to 8.
6 and 2 add to 8 but don't multiply to 15.
5 and 3. This in some form is your answer, but handle it carefully.
(x - 5)(x - 3)
The 5 and 3 both have to be minus.
