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.
Answer:
Red
Step-by-step explanation:
To solve this we can use substitution.
We know that y=4-x, so we can substitute "4-x" into anywhere that y appears in the first equation.
4-x=3x-8
Now we can move the variables to one side and the numbers to the other.
We can do that by adding x to both sides.
4=3x-8+x
Now, let's add 8 to both sides.
4+8=3x+x
Combine like terms.
12=4x
x=3
Now, we can plug that back into the equation to find y.
y=3(3)-8
y=8
y=1
So our answer is (3,1)
M∠B = x
m∠A = 4x
x + 4x = 180
5x = 180
x = 180/5
x = 36
m∠B = x = 36°
m∠A = 4x = 4 * 36 = 144°
