Replace all the variables that we know the value for.
-3 = |x|
Make to equations from this one.
-3 = x and -3 = -(x)
Solve the first one.
-3 = x
x = -3 <-- Switch it around
-3 = -(x)
-(x) = -3 <-- Switch it around
x = 3 <-- Divide both sides by -1
So, there are two possible answers, -3 and 3.
<span>150% to decimal = 1.50 since 100% = 1

-2-2 = -4 m=-1/2
<u>
</u>plug one of the coordinates and the slope into y=mx+b, and solve
<u />8=-1/2(2)+b
8=-1+b
9=b
Final Answer: y = -1/2x + 9

Step-by-step explanation:
Answer:
The Answer is: x = 1.444 with repeating 4.
Step-by-step explanation:
212x - 34(2x + 5) = 38
212x - 68x - 170 = 38
212x - 68x = 38 + 170
144x = 208
x = 208/144 = 52/35 or 1.444
Proof:
212(1.444) - 34(2(1.444) + 5) = 38
306.128 - 34(7.888) = 38
306.128 - 268.192 = 37.936 or approximately 38
Hope this helps! Have an Awesome Day!! :-)
