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.
Answer:
Sometimes true
Step-by-step explanation:
There is only one x value that satisfies the equation.
4x + 1 = 3
4x = 2
x = 1/2
Answer:
<u>The slope-intercept form </u>
Here m is the slope and b is y-intercept
<u>When b= 0</u>
and
In this case Avery's method works
<u>When b≠0</u>
In this case Avery's method brings wrong outcome
just look up math papa algebra calculator it gives you the answer and explains it step by step :)
