Snowcat [4.5K]

Answer:

40 square yards

Step-by-step explanation:

The backyard is rectangular and it's dimensions are 7 yards long and 8 yards wide.

The area of a rectangle is given as:

A = L * W

where L = length

W = width

Therefore, the area of the backyard is:

A = 7 * 8 = 56 square yards

Elliana wants to plant sunflowers on 16 square yards of the backyard and the rest of the backyard will be used for a pool.

The area left for the pool will therefore be:

56 - 16 = 40 square yards

40 square yards will be left for the pool.

A third of a number minus 8 is 17 What is the number

katrin [286]

Answer:

<h2>The number is 75</h2>

Step-by-step explanation:

Let the number be x

A third of a number is written as

$\frac{1}{3} x$

A third of a number minus 8 is written as

$\frac{1}{3} x - 8$

The result is 17

We have

$\frac{1}{3} x - 8 = 17$

<u>Add 8 to both sides of the equation</u>

That's

$\frac{1}{3} x + 8 - 8 = 17 + 8 \\ \frac{1}{3} x = 25$

<u>Multiply through by 3 to eliminate the fraction</u>

That's

$3 \times \frac{1}{3} x = 25 \times 3 \\ x = 2 5 \times 3 \\ x = 75$

<h3>The number is 75</h3>

Hope this helps you
