X2+y2=65............1
X2-3y=37..............2
÷both equation. 1 by 2
X+y=32,5
X=32,5-y......... 3
Sub 3 in 2
(32,5-y)2-3y=37
65-2y-3y=37
65-5y=37
-5y=37-65
-5y= - 28 divide both sides by - 5
Y=5,6........ 4
Sub 4 in 3
x=32,5-y
=32,5-5,6
=26,9
Hope it's the way you wanted it
Answer:
the cost of making each paperweight = $0.81
Step-by-step explanation:
First let us calculate the selling price for each paperweight as follows:
total amount gotten = $230.85
number of paperweights = 95
∴ 95 paperweights = $230.85
∴ 1 paperweight = 230.85 ÷ 95 = $2.43
selling price of 1 paperweight = $2.43
Next, let the cost of making 1 paperweight be 'x'
selling price of paperweight = cost of making + profit gotten
The cost of making the paper weight (x) plus the profit made on the paper weight (2x) equals the selling price of each paper weight.
x + 2x = 2.43 (the profit the club makes is two times as much as the cost to make each paperweight)
∴ 3x = 2.43
x = 2.43 ÷ 3 = 0.81
Therefore, the cost of making each paperweight = $0.81
Answer:
48.75
Step-by-step explanation:
$5 → 1/3 pound
$1 → 1/3 ÷ 5 = 1/3 x 1/5 = 1/15 pound
$9 → 1/15 pound x 9 = 9/15 pound = 3/5 pound
