Answer: 
x + 
x = 2x - 25
Step-by-step explanation:
First, let's analyze the phrase "the sum of one-half and two-thirds the number". This would translate to:
x + x
Then it says the last part of the expression is "twenty five less than twice the number"
2x - 25
Then, equal the two parts of the equation to each other.
x + x = 2x - 25

Answer:
number of tape sides = 2.1667 tape sides
Explanation:
We know that each song took 1/6 of a side of tape to be recorded.
To know how many tape sides were used to record 13 songs, all we have to do is cross multiplication as follows:
1 song ..................> 1/6 of a tape side
13 songs ..............> ?? tape sides
Number of tape sides = [(13) * (1/6)] / 1
number of tape sides = 2.1667 tape sides
Hope this helps :)
Answer:
4/5
Step-by-step explanation:
use rise over run up 4 over 5!!!
In a triangle, the three interior angles always add to 180°
5x + 7x + 8x = 180
20x = 180
x = 180/20
x = 9
m∠1 = 5x = 5*9 = 45°
m∠2 = 7x = 7*9 = 63°
m∠3 = 8x = 8*9 = 72°
Answer:
45°, 63° and 72°
