The last one: x/2=45; x = 90
the problem says: half of a number is 45.

let's use x to represent this number
we know that dividing by 2 halves a number, so, x/2 = 45

to get x alone, we multiply 2 by 2 to cancel it out. so, multiply by 2 on both sides

x/2 • 2 = 45 • 2

x = 90

hope this helped!

Answer:

E: L is perpendicular to a line with slope $-\frac{3}{2}$ .

Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of $\frac{2}{3}$ is $\frac{3}{2}$ (remember, to get the reciprocal, simply switch the numerator and the denominator).

So, the negative reciprocal of $\frac{2}{3}$ is $-\frac{3}{2}$ . This represents the slope of a line that is perpendicular.
