Slav-nsk [51]
To answer this you will need to know that there are 43,560 square feet in 1 acre.

1. Half of this is 43560/2 or 21780 square feet.

2. Out of this amount Blake has already mowed 3/5 of the lawn. This means he must mow 2/5 (1 - 3/5) more.

2/5 of 21,780 ft.² can be represented this way:

2/5 x 21780 =?

He needs to mow 8712 ft.² more.

Identify the slope and y-intercept for 2x + y = 3
kotegsom [21]

Step-by-step explanation:

The formula for the slope is <em>y=mx+b</em>, where <em>m</em> is the slope and <em>b</em> is the y-intercept. Since 2 is being multiplied by <em>x</em>, that means it is the slope. The variable <em>y</em> is being added, so it has to be the y-intercept.

Answer:

2=slope & y-intercept=y
