For this case we have that each student takes 8 \ frac {3} {4} minutes to perform and play 3 songs. Then, we convert the mixed number to a fraction:
Thus, each student takes
minutes.
If there are 9 students in the recital then we have:
minutes.
Thus, the recital lasts at least 78.75 minutes.
Answer:
The recital lasts at least 78.75 minutes.
Answer:
The answer to your question is: ( - 24 / 29, ∞ )
Step-by-step explanation:
6x + 3 < 8 (8x + 6) + 3
6x + 3 < 64x + 48 + 3
6x + 3 < 64x + 51
6x - 64x < 51 - 3
- 58 x < 48
x > - 48 / 58
x > - 24 / 29
( - 24 / 29, ∞ )
Answer:
5.6
Step-by-step explanation:
by dividing
So we start off with what 4 numbers added together equal 32.
