Mabel spends 4 hours editing a 3 minute video. she edits at a constant rate. how long does mabel spend to edit a 9 minute video?

she spends 4 hours on a 3 minute video
so there are 60 minutes in an hour
4 hours with 60 minutes- 4x60=240
so she spent 240 minutes on a 3 minute video
3 divided by 240
3/240= 0.0125
so her constant rate is 0.0125 minutes an hour
so divide 9 minutes by her constant rate
9/0.0125 = 720
so she spends 720 minutes on a 9 minute video.
divide 720 by 60 since there are 60 minutes in an hour
720/60 = 12
so she spends 12 hours on a 9minute video

4<br> Subtract. Write the expression below in simplest form.<br> (-x + 3) - (4x-10)
ycow [4]

Answer:

Step-by-step explanation:

(-x + 3) - (4x - 10)

= - x + 3 - 4x + 10 (because when you see the minus sign you have to change all the sign inside the bracket)

= -5x + 13 (this step is just subtract -x and -4x and 10 + 3)

What are the factors to the equation 4x2-52x + 169 121? A 4(x-1)(x+12) B 4(x + 1)(x - 12) C. 4(x + 1)(x+12) D. 4(x-1)(x - 12)
Bingel [31]

The given equation is,

4x^2-52x+169=121

Simplifying the above equation,

\begin{gathered} 4x^2-52x+169-121=0 \\ 4x^2-52x+48=0 \end{gathered}\begin{gathered} 4x^2-13\times4x+4\times12=0 \\ 4(x^2-13x+12)=0 \\ 4(x^2-12x-1x+12\times1)=0 \\ 4(x(x-12)-1(x-12))=0 \\ 4(x-12)(x-1)=0 \end{gathered}

Therefore, the factors of the given expression is 4(x-1)(x-12).
