Answer: The correct answer is $150.
Step-by-step explanation: If you did not use the coupons while shopping you would have spent $150. The method to calculate this is to divide the amount that you paid by the percentage that you paid.
The formula that you need to use is $120/.8 = $150.
D is your answer I’m 80%sure
Answer:
2 trees
Step-by-step explanation:
Since the city is planting a tree every 20 feet across Dayton Avenue, then we need to find the length of the side that is on Dayton Avenue.
We are missing 3 sides to this. But it's extremely important to note that the side adjacent to Dayton Avenue is the same length as the other missing two sides combined. This is because both of these lengths contain the 1 feather and 2 feather mark - these signify congruence.
This means that the side lengths of both of them combined will be 
This means the side adjacent to Dayton Avenue is
feet long.
Now that we know that the side is 57 feet long, we have to divide this by 20, as a tree is being placed every 20 feet. If we get a decimal, we will have to round down because it gets planted only, and only if, 20 more feet has been accomplished. If we are a fraction of the way there, a tree doesn't get planted.

Rounding down gets us 2.
Hope this helped!
1) question 18 of 20
-7x/5-(4y)=7
4y=-7x/5-(7)
y=-7x/20-(7/4).
if x=0 ⇒y=-7*0/20-7/4=-7/4 ⇒y-intercept is-7/4
fi y=0 ⇒ -7x/20-(7/4)=0
-7x/20=7/4
x=(7*20) / [4*-(7)]=-5 ⇒x-intercept is -5
Solution: D) x-intercept is -5 ; y-intercept is -7/4
Question 19 of 20
P₁=(x₁,y₁)
P₂=(x₂,y₂)
m=slope
m=(y₂-y₁) / (x₂-x₁)
Then:
A(1,7)
B(10,1)
m=(1-7) / (10-1)=-6/9=-2/3.
Solution: B)-2/3
Question 20 of 20:
y-y₀=m.(x-x₀)
A(4,3)
B(-4,-2)
m=(-2-3) / (-4-4)=-5/-8=5/8
y-3=(5/8).(x-4)
y=5x/8-(20/8)+3
y=5x/8-(20/8)+24/8
y=5x/8+(4/8)
y=5x/8+1/2
solution: B) y=5x/8+1/2
