This should help you. I do not want to give you the answers. I want you to do them yourself with the instructions I gave you and then come back and post them when you are done so I may check them. Okay?
Answer:
it is 1:5
Step-by-step explanation:
The table shows the amount of red paint that can be added to different amounts of white paint while making a custom paint color:
Paint Color
Quarts of Red Paint Quarts of White Paint
4 20
5 25
7 35
8 40
Which statement is true about the
ratio of red paint to white paint in the paint color?
it is 1:16
it is 16:1
it is 5:1
it is 1:5
Ratio of red paint to white paint in the paint color = 4 : 20
= 4/20
= 1/5
= 1 : 5
Ratio of red paint to white paint in the paint color = 1 : 5
Ratio of red paint to white paint in the paint color = 5 : 25
= 5/25
= 1/5
= 1 : 5
Ratio of red paint to white paint in the paint color = 7 : 35
= 7/35
= 1/5
= 1 : 5
Ratio of red paint to white paint in the paint color = 8 : 40
= 8/40
= 1/5
= 1 : 5
Answer: Area of the walkway: 4.5(4x+6) - 4(2.5x+3.5)
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Area of the garden: 4(2.5x+3.5)
Combined area of the garden and the walkway: 4.5(4x+6)
Area of the walkway = A
So, the combined area of the garden and the walkway is equal to sum of both areas:
4(2.5x+3.5)+ A = 4.5(4x+6)
Solving for A:
A = 4.5(4x+6) - 4(2.5x+3.5)
Area of the walkway: 4.5(4x+6) - 4(2.5x+3.5)
8.75n=61.25
In order to solve it, you have to divide 61.25 by 8.75 in order to get your answer.

T3 - 6=6
T3=12
then T2-T1=4
6-T1=4
T1=2
T4-T3=8
T4-12=8
T4=20
Therefore terms= 2,6,12,20
1st difference= 4,6,8
2nd difference= 2,2,....
2a=2
a=1
3a+b=4
3(1) + b=4
b= 1
a+b+c= 2
c= 2-1- 1= 0
giving Tn= n^2 + n
T12 = 12^2 + 12 = 156
