\bf \begin{cases} UW = m\\ WX = y+14 \end{cases} ~\hfill WX = y+14\implies \boxed{W=\cfrac{y+14}{X}} \\\\\\ \stackrel{\textit{doing substitution on the 1st equation}}{UW = m\implies U=\cfrac{m}{W}\implies }U=\cfrac{m}{\frac{y+14}{X}}\implies U=\cfrac{\frac{m}{1}}{\frac{y+14}{X}} \\\\\\ U=\cfrac{m}{1}\cdot \cfrac{X}{y+14}\implies U=\cfrac{mX}{y+14}\implies \stackrel{\textit{multiplying both sides by X}}{UX=\cfrac{mX^2}{y+14}}

What percent of students ran the mile in 12 minutes or less?
otez555 [7]
41% of students ran in 12 minutes or less.

Using the histogram we see that there were 2+12+11+9=34 students that ran.  Out of those, 2+12=14 ran in 12 minutes or less (the first two bars).

14/34 = 0.411 = 41%.

Can someone help me with this math problem
Elis [28]

Answer:

C. Divide both sides of the equation by -2.

Step-by-step explanation:

The goal of the equation is to isolate x. In order to do that we have to remove the '-2' by doing the inverse operation. That is the opposite operation, for example addition and subtraction, multiplication and division.

Since x is being multiplied by -2, we do the inverse which is division.
