if she can fly from Washington DC to Ocean City MD 162 miles in 18 minutes how long would it take her to travel 486 miles???

o-na [289]

We can put it like this
162/18=486/x
cross multiply
162*x = 486 * 18
162*x = 8748
divide both sides by 162
x = 54

It will take her 54 minutes to travel 486 miles

Hope this helps :)

Two thirds of a number is no more than -10

Aliun [14]

Let x be the number in the problem. When it states that x is "no more than -10", it means than it is less than or equal to -10. So, we have

$\frac{2}{3}$ x≤-10

In order to cancel out the $\frac{2}{3}$ on the left and isolate x, we multiply both sides by $\frac{3}{2}$ (since $\frac{3}{2}$ · $\frac{2}{3}$ =1). Thus, we have

x≤-10· $\frac{3}{2}$ =-15

Therefore, x≤-15
