Answer:
3x-3(6) = 3x-18
Step-by-step explanation:
Answer:
y=20x+25, this equation is linear, the rate of change is constant
Step-by-step explanation:
She starts with 25$, that doesn't change so its our constant. Let x represent each week. Each week she ears 20$
So, let y represent the total amount of money she has
y=20x+25, this equation is linear, the rate of change is constant
The third one should be right
Step 1) Find the total circumference
C = pi x d
d = r x 2
d = 5 x 2 = 10
C = pi x 10 = 10pi
Step 2) Find 1/4 of the circumference
10pi / 4 = 2.5pi = 7.85
Step 3) Add the two radii sides to the 1/4 circumference
7.85 + 5 + 5 = 17.85
C = 17.85 feet
Hope this helps! :)
There will be 100 hand shakes because you would do 10x10 which is 100
