So 70 minus 25=45
45/4=11 because you can't burn 1/4 of a song on the disk
so 11 songs
Answer:
(8, 4 )
Step-by-step explanation:
Given the 2 equations
5x - 5y = 20 → (1)
- 3x + 5y = - 4 → (2)
Add the 2 equations term by term to eliminate the y- term
2x + 0 = 16
2x = 16 ( divide both sides by 2 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (2)
- 3(8) + 5y = - 4
- 24 + 5y = - 4 ( add 24 to both sides )
5y = 20 ( divide both sides by 5 )
y = 4
solution is (8, 4 )
Answer:
Step-by-step explanation:
Let x represent the number if people that she can invite.
Yolanda is doing a party for her daughter. She has spent $130 on the venue and Will spend $18 per person for food. This means that the total amount that she would spend if she invites x persons is
130 + 18x
She wants to spend no more than $500. Therefore, inequality to help her determine how many people she can invite would be
130 + 18x ≤ 500
