PLEASE HELP ME !!!!!!!!!!!!!!!!!<br>LET ME KNOW IF ITS RIGHT
Savatey [412]
Okay. So the song lasts 221 seconds. 45 seconds have already beem done and 22 seconds is done in an hour. The equation would be set up like this:

45 + 22h = 221

Just by looking at the answer choices, A is already eliminated because it doesn't incorportate the 45 seconds. B does include the 45 seconds, but it subtracts, and in this case, we add time, not subtract. D is eliminated, because the h variable does not go with 45. The only equation that works is C and when you solve it, you get 8 hours. The answer is C.

Note: you solve the equation above by subtract 45 from both sides to get 176 = 22x, and dividing both sides by 22 to get x = 8.

The product of 16 and 4 less than a number is 208. Find the number.
svlad2 [7]
This is a word problem signifying an algebraic expression.

Translating this to mathematics:

16x - 4 = 208

add 4 to both sides.

16x = 212 

divide 16 to both sides. 

x = \frac{212}{16} 

this is:

x = 13.25
