Determine how much money did the carpenter start with
The total money with the carpenter is $318.4
Given:
let
x = <em>total money with the carpenter</em>
<em>Bags of sand</em> = 7/8 of x
= 7/8x
<em>Money remaining</em> = x - 7/8x
= (8x-7x) / 8
= 1/8x
<em>Bags of bunting bags</em> = 1/2 of 1/8x
= 1/2 × 1/8x
= 1/16x
<em>Money left </em>= $19.90
<em>Total money = bags of sand + bag of bunting flag + money left</em>
x = 7/8x + 1/16x + 19.90
x = (14x + x) / 16 + 19.90
x = 15/16x + 19.90
x - 15/16x = 19.90
16x - 15x / 16 = 19.90
x/16 = 19.90
divide both sides by 1/16
x = 19.90 ÷ 1/16
= 19.90 × 16/1
= 318.4
Therefore, the total money with the carpenter is $318.4

Answer:
Step-by-step explanation:
Note that the quadratic formula has that "plus or minus" due to our taking the square root of some quantity. No square root is involved in the two formulas you've posed.
I have two suggestions here:
1) Write " (x plus or minus y)^2 = x^ plus or minus 2 times xy + y^2 " Note that a + on the left side corresponds to a + on the right side, and same with - .
2) Memorize these two formulas, which in most algebra textbooks you'll find in the section "special products and factoring."
Answer:
Step-by-step explanation:
Since you want to get q only and q appears in both side of the equation. Try to isolate q to one side.
1) Expand 2(q+p)
2q + 2p = 1 + 5q
2) Move all q terms to one side
5q - 2q = 2p - 1
3q = 2p - 1
3) Divide 3 on both side (to isolate q)
q =
