Answer:
y = 27
Step-by-step explanation:
y/3 + 2 = 11
First subtract 2 from each side
y/3 + 2-2 = 11-2
y/3 = 9
Then multiply each side by 3
y/3 *3 = 9*3
y = 27

Answer:
3
Step-by-step explanation:
The product has decreased by 80 %
<em><u>Solution:</u></em>
The product of the original numbers: xy
One number is decreased by 75 %
Let x be the number decreased by 75 %
new number = x - 75 % of x

Another number is decreased by 20 %
Let y be the number decreased by 20 %
new number = y - 20 % of y

<em><u>Now the product is given as:</u></em>

<em><u>Now we have to find the percent decreased</u></em>
Subtract new product and original product and then divide by original product . Multiply the result by 100 to get percentage

Here negative sign denotes decrease
Thus the product has decreased by 80 %
