Answer:
Paulo will need to mow at least 31 lawns to reach his goal of $2115.00.
Step-by-step explanation:
1. This is an inequality problem. The solution for this problem will involve creating in inequality to solve for the answer. To create an inequality, it is important to keep your information organized concisely.
Total = $2115.00
Lawn = $70.00
x = Amount of Lawns
2. From this information, the inequality can be formed.
70x 
2115
3. Using the order of operations, solve the inequality.
x 2215/70
x 30.21
4. The minimum number of lawns Paulo needs to mow is 31 lawns to meet his goal of $2115.00.

Answer:
The mean is 21.62 which is approximately 22
Step-by-step explanation:
mean= 15+20+10+12+20+16+80+18/8=21.62 because
mean= sum of all numbers/numbers mentioned
The one for 9 is 15
The one for 7 is 11
The one for 1 is -1
The one for 0 is -3
First, let's find the x and y intercepts
In the first equation
y - 4x = -1
Put x =0
y= - 1
(0, -1)
Put y=0 and the n solve for x
0 - 4x = -1
-4x = -1
x=0.25
(0.25 , 0)
The points for the first equation is (0, -1 ) and (0.25, 0)
Next is to find the intercts for the second equation
y + x = 4
put x=0
y = 4
(0, 4)
Put y =0
0 + x = 4
x = 4
( 4, 0)
The points for the second equation are;
(0, 4) and (4, 0)
Below is the graph
