Answer:
4
Step-by-step explanation:
Solve. To do so, flip the second fraction, and change the division sign to a multiply:
4/5 ÷ 1/5 = 4/5 x 5/1
Multiply across:
(4 x 5)/(5 x 1) = 20/5
Simplify:
20/5 = 4
4 is your answer.

You will need 1 more equation
Answer:
So first you do $0.50 x 3 = 1.5
then you add that to $12.00
$12.00 + 1.5 = 13.5
13.5 is the cost of one pizza.
Since they bought 12:
The total cost of the 12 pizza is $162 <== not important
<u>13.5 divided by 8 is 1.687</u>
<u>round 1.56875 to the nearest cent 1.7 = $2</u>
so each slice costs $2
Answer:
you have to finish posting the question in order to get a proper answer
Y= kx+b, k-slope, b-intercept
so
2=k*1+b
7=k*2+b
12=k*3+b
17=k*4+b
solve these two equation:
2=k*1+b
7=k*2+b
second minus first is 7-2=2k-k+b-b
5=k,
so we know k=5
put this in any equation 2=5*1+b
b=2-5
b=-3
check this in
12=5*3-3 - right
17=5*4-3 - right
Answer: y=5x-3
