Veronica has 7 yards of ribbon. Each bow requires 3/4 of a yard ribbon. How many bows will she be able to make with the ribbon s

Sonbull [250]

Answer && Step-by-step explanation:

7 yards == 4/4

by simple arithmetic remove 3/4 from 7 until you can no longer obtain 3/4 from it

7 => 6*1/4

6*1/4=>5*2/4

5*2/4=>4*3/4

4*3/4=>4

4=> 3*1/4

3*1/4=>2*2/4

2*2/4=>1*3/4

1*3/4=>1

1=>1/4

1/4 remains and 9 bows were made

Aaron wants to mulch his garden. His garden is x^2+18x+81 ft^2 One bag of mulch covers x^2-81 ft^2 . Divide the expressions and

blsea [12.9K]

Answer:

Step-by-step explanation:

Given

Garden: $x^2+18x+81$

One Bag: $x^2 - 81$

Requires

Determine the number of bags to cover the whole garden

This is calculated as thus;

$Bags = \frac{x^2+18x+81}{x^2 - 81}$

Expand the numerator

$Bags = \frac{x^2+9x+9x+81}{x^2 - 81}$

$Bags = \frac{x(x+9)+9(x+9)}{x^2 - 81}$

$Bags = \frac{(x+9)(x+9)}{x^2 - 81}$

Express 81 as 9²

$Bags = \frac{(x+9)(x+9)}{x^2 - 9\²}$

Evaluate as difference of two squares

$Bags = \frac{(x+9)(x+9)}{(x - 9)(x+9)}$

$Bags = \frac{(x+9)}{(x - 9)}$

Hence, the number of bags is $Bags = \frac{(x+9)}{(x - 9)}$
