Answer:
0.825
Step-by-step explanation:
In order to make the denominator 100, we must multiply both the numerator and denominator by 2.5
33*2.5 = 66 + 16.5 = 82.5
33/40 = 82.5/100
Now we solve, 82.5/100 = 0.825
Ok
x = -1
<em><u>Add like terms (3 and 7, 2x and -10x and -x)</u></em>
x + 3 + 7 = 2x - 10x - x
x + 10 = -9x
<em><u>Subtract x from both sides:</u></em>
10 = -10x
<em><u>Divide both sides by -10:</u></em>
-1 = x
rearrange to get x < -4
