If 20 wall paintings can be done in 4 weeks how much time does it take to prepare 80 wall paintings using unit rate form?

In-s [12.5K]

Simplest way would be to find out how many painting more it would be 80 from 20. It is four times more drawings. Now since you know it is 4x more then you can simply multiply 4 time 4 (4*4) because it would be the weeks it takes him by the times it would be. It would be 16 weeks in total.

By selling old CD Sarah has a store credit of $153 a new CD cost $18 what are the problem numbers of new cCD Sarah can buy

DiKsa [7]

Rileyflipflop, $\frac{153}{18}$ = 8 $\frac{1}{2}$ , since she can't buy half a CD, she's limited to no more than 8 CDs. If x = the cost of one CD, then x CDs cost $18x. Since we are limited to $153, our equation looks like... 18x < 153x < 8 $\frac{1}{2}$ Again, since we can't buy half a CD, your answer should actually be... x ≤ 8 since we can buy 8 CDs or fewer.

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?

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