<span>The question said that Juan earns 5 percent on the first ten suits sold. Commission earned on the first ten 250.00 dollars suits = 5% of 250.00 times 10 suits = 0.05 x 250 x 10 = $125.00. The question said that he earns an additional 3 percent on additional suits exceeding 10 suits making a total of 8 percent. Since Juan sold 13 suits, he sold 3 additional suits. 8% of 250.00 times 3 suits = 0.08 x 250 x 3 = $60. Therefore, total commision = $125 + $60 = $185.00</span>
Two equivalent ratios would be 14:22 & 21:33
Area = Length x Width
Substituting the given values:
16S^2 t = 8St^2 x Width
Manipulating for Width:
Width = 16S^2 t / <span>8St^2
Rewriting the squared terms in simplified form :
</span>Width = 16 x S x S x t / <span>8 x S x t x t
</span>Cancelling the like terms
Width = 16 x S / <span>8 x t
</span>Cancelling the numeric terms :
Width = 2S / <span>t</span>
You are correct, y would equal -1
But let me show you why
-5y+8=-3y+10
----------------------------------------
Add 3y to each side
<span>-5y+8+3y</span>=-<span>3y+10+<span>3y
</span></span>-2y+8=<span>10
</span>------------------------------------------------
Subtract 8 on each side
<span><span>-2y+8-</span>8</span>=<span>10-8
</span><span><span>-2y</span></span>=<span>2
</span>--------------------------------------------------------
Now divide each side by -2
-2y ÷ -2 = 2 ÷ -2
y = -1

Hope I helped, Have a great day! :D
1. multiply to -18 add to -17 = Multiplying -18 and 1 will give -18 as the result and then on adding -18 and + 1 the result comes to -17
