Answer:
5 hours
Step-by-step explanation:
Step one:'
given data
Angelo charges a one time fee of $50 plus $15 per hour
let the total charge be y
and the number of hours be x
y= 50+15x----------------1
Deborah charges a one time fee of $25 plus $20 per hour
y= 25+20x----------------2
equate 1 and 2 to find x
50+15x=25+20x
collect like terms
50-25= 20x-15x
25= 5x
divide both sides by 5
x= 25/5
x= 5 hours
Answer:
5
Step-by-step explanation:
You do 12 x 3 which is 36.
you then do 1/3 x 3 which is 1.
36-1 is 35.
you then do 4x3 which is 12.
you then do 12-5 which is 7.
you then do 35÷7=5
this is why it is 5.
C. X= 18
ex:
4x-7=7x-61
(They equal eachother)
you solve and get 18
