Answer:
x = -5/6
Step-by-step explanation:
Multiply both sides by (3x+1):
3x - 2 = 3 (3x + 1)
Distribute:
3x - 2 = 9x + 3
Add 2 to both sides:
3x = 9x + 5
Subtract 9x from both sides:
-6x = 5
Divide both sides by -6:
x = -5/6

Answer:
a. $20.45
b. $24.55
c. $4.55
Step-by-step explanation:
In this question, we are asked to calculate the cost price and profit or loss selling a pair of shoes.
we proceed as follows
Firstly, we want to find the cost price given the selling price and the mark up percentage.
mathematically;
profit =( selling price - cost price)/cost price * 100%
here our profit is 120% with the cost price being $45. we plug these values
120 = 45-cp/cp * 100%
120cp = 100(45-cp)
120cp = 4500 -100cp
220cp = 4500
cp = 4500/220 = $20.45
His profit is selling price - cost price = 45 - 20.45 = $24.55
His profit selling same shoe for $25 is 25-20.45 = $4.55
Answer:
7x + 2y = 24 8x + 2y = 30. Subtract -x = -6 x = 6. Substitute x = 6 into 7x + 2y = 24 7(6)+ 2y = 24 42 + 2y = 24 2y = 24 - 42 2y = -18 y = -9 {6,-9} ...
