B is where it starts on the y axis.
m is the slope.
Answer:
6 hours
Step-by-step explanation:
Let
x----> the number of hours worked at the donut shop
y----> the number of hours worked at the school bookstore
we know that
x+y=20
x=20-y -----> equation A
10.25x+8.75y=196 -----> equation B
Substitute equation A in equation B and solve for y
10.25(20-y)+8.75y=196
205-10.25y+8.75y=196
10.25y-8.75y=205-196
1.5y=9
y=6 hours at the school bookstore
64-128-256
each step double previous number
Answer:
4. (Theater) 39%
5. (Bowling) 20%
6. (Pets) True, false, true
Hope this helps!
