2 and 1/4 = 9/4
4 and 1/12 = 49/12
3 and 2/3 = 11/3
Perimeter = 9/4 + 49/12 + 11/3
= 27/12 + 49/12 + 44/3
= 120/12
= 10inches
30.6 because 10.2 times 30 is 30.6
Answer: 1-3 is a, and then 4-5 is c
Step-by-step explanation:
You are given the slope = 4 and a point is (-1,1)
The equation of a line is written as y - mx + b where m is the slope and b is the y intercept
Using the slope you now have y = 4x + b
Solve for b by replacing x and y with the values of the point:
1 = 4(-1) + b
Simplify:
1 = -4 + b
Add 4 to both sides:
b = 5
The equation of the line is C.) y = 4x + 5
Answer:
.75 x 10 = $7.5
.25 x 30 = $7.5
They have the same amount so Noah is right
