The temperature in frostburg is -7.This is 18 less than the temperature in coldspot.Find the temperature of coldspot

Drupady [299]

If the temperature in frostburg is 18 less than the temperature in coldspot, then the following equation compares the two temperatures:

$f = c-18$

where $f,c$ are the temperatures in frostburg and coldspot. Since we're given $f$ , we can solve for $c$ :

$-7 = c-18 \iff c = -7+18 = 11$

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
