Answer:
65
Step-by-step explanation:
Since 39 is equal to 60%, and 60% is also equal to 60/100, then 39/x (x is the total we are solving for) is equal to 60/100.
Cross multiply so 39/x = 60/100
39*100 = 60x
3900 = 60x (divide both sides by 60)
65 = x
Answer:
its the second choice most of the songs were 3.4 minutes long just took the test
The equation given in the question has one unknown variable in the form of "x" and only one equation is required to find the value of the unknown variable. So it is absolutely possible to find the exact value of "x".
6(-3 - x) - 2x = 14
-18 - 6x - 2x = 14
-18 - 8x = 14
Multiplying both sides of the equation by -1 we get
8x + 18 = - 14
Dividing both sides by 2 we get
4x + 9 = - 7
4x = - 7 - 9
4x = - 16
x = - 16/4
= - 4
So the value of "x" comes out to be equal to - 4. I hope the procedure is clear enough for you to understand.
