The budget for a school dance is $390.00. Decorations and refreshments cost $150.00. The band charges a fee of $100.00 plus an additional $35.00 per hours. What is the maximum number of hours the school can have the band play at the dance?
Answer:
The maximum number of hours the school can have the band play at the dance is 4.
Step-by-step explanation:
150 + 100 + 35x ≤ 390
250 + 35x ≤ 390
subtract 250 from both sides
35x ≤ 140
divide by 35 on both sides
x ≤ 4

8x=120
step 3 divide each side by 8
x=15
Answer:
z=74
x=15
Step-by-step explanation:
z=74 because vertical angles are the same
you have to add the z and 8x-14 and set it equal to 180 because the angles at supplementary
