Answer:
A: - 15x - 30/7
Step-by-step explanation:
-5 (3x - 6/7)
Just distribute -5 to the values inside the parentheses.
-5 · 3x = -15x
-5 · 6/7 = -30/7
Now form it together:
-15x - 30/7
Answer:
She played the music 5 times as long in the first round as she did the second round
Step-by-step explanation:
All i know is that distance isnt my thing and i dont know how to do it
9.68x + 21.6 - 6.23x = 2.3x + 17
Combine like terms on the left side:
3.45x + 21.6 = 2.3x + 17
Subtract 2.3x from both sides:
1.15x + 21.6 = 17
Subtract 21.6 from both sides:
1.15x = -4.6
Divide both sides by 1.15:
X = -4
#13 isn't too bad my friend. Just do 21-9, then divide by 4. So each ticket was $3.
15 is similar too. so he has 9 more than half. Take 9 away from 21, and you have 12. Double that, and you have the original 24.
