72:80
9:10
Divide 72 and 80 by 8 to simplify it and get the ratio
Answer: the second one
Step-by-step explanation:
There are several ways to do this by converting<span> the percentage to a fraction </span><span>by placing thee expression </span><span>over </span><span /><span><span><span><span><span><span><span>100</span></span></span></span></span></span><span>100</span></span><span>. Percentage means out of 100 and it will look like this 170/100.
Reduced the expression. 17/10
or in whole number it is 1 17/10</span><span />
We need to account for both x values on either side of the length, and width.
Thus, the length becomes 10 + x + x = 10 + 2x
and the width becomes 5 + x + x = 5 + 2x
For the second question, I'm assuming we don't account for the area that is covered by the garden.
Then we can say that the path is measured by: (5 + 2x)(10 + 2x) - 50, which is the area of the garden itself.
(5 + 2x)(10 + 2x) - 50 = 54
Expanding the brackets:






x = -9, or x = 3/2
Since x > 0, then x ≠ -9
Thus, the only x-value we can take is x = 3/2
