Answer:
24 in long by 12 in wide.
Step-by-step explanation:
l=2w
288=(2w)×w
288=2w^2
144=w^2
12=w
use w=12 to solve for l
l=2(12)
l=24
3x-2=2x-7
We simplify the equation to the form, which is simple to understand
3x-2=2x-7
We move all terms containing x to the left and all other terms to the right.
+3x-2x=-7+2
We simplify left and right side of the equation.
+1x=-5
We divide both sides of the equation by 1 to get x.
x=-5
Answer: 4 paddles
Step-by-step explanation:
Mr. Jones buys the paddle for $35 and sells at 180% of the purchase price:
= 35 * 180/100
= $63
For the number of paddle sales to be at least $250, he should sell:
= 250/63
= 3.97
= 4 paddles
Since we know the length (L) to width (W) ratio is 3 to 1, we can put the ratio in the form of a fraction and solve for the unknown length (L’).
Therefore we have L/W = 3/1 = L’/33
Moving the width of 33 to the other side of the equation, we have 3/1 * 33 = L’
99/1 = L’
99 = L’
Therefore the length L’ should be 99cm if the width is 33cm.
