A middle school team scored three field goals worth three points each and two touchdowns worth six points with a single extra po
Bezzdna [24]
The team scored twenty-three points in total. 
This word sum can be worked out as follows:

Three field goals worth three points each is equal to nine points (3 x 3 = 9).
Two touchdowns were scored; each touchdown is worth six points. This equals twelve points (2 x 6 = 12).
Lastly, the team was awarded a bonus point for each touchdown they scored. They scored two touchdowns so they were awarded two extra points (2 x 1 = 2). 
Therefore, we have three subtotals: nine for the field goals; twelve for the touchdowns and two for the bonus points. The equation for this word sum is 9 + 12 + 2 = 23

The graph shows the first 45 minutes of Darlene's bike trip. If she continues at a constant rate, how far will she travel in two
julia-pushkina [17]

the slope or average rate of change for the trip from the graph is just rise/run.  Now, let's take a look at those values to get it

\bf slope\implies \cfrac{rise}{run}\implies \cfrac{distance}{time(mins)}\implies \cfrac{9}{45}=\cfrac{8}{40}=\cfrac{7}{35}=\cfrac{6}{30}=\cfrac{5}{25}\implies \stackrel{\stackrel{slope}{\downarrow }}{\cfrac{1}{5}}

so the slope of it is 1/5, 2 hours is 120 minutes, what would be the distance value on 120 minutes?

\bf \cfrac{distance}{time(mins)}=\stackrel{slope}{\cfrac{1}{5}}\qquad \qquad \cfrac{\stackrel{miles}{d}}{\underset{minutes}{120}}=\cfrac{1}{5}\implies d=\cfrac{120}{5}\implies d=24
