Answer:
x = 3
Step-by-step explanation:
First, distribute 3 into the parenthesis:
3(4 - 2x) = -2x
12 - 6x = -2x
Next, combine your x variables by adding +6x to both side:
12 - 6x = -2x (-6x and +6x cancel out)
+6x +6x
12 = 4x (divide 12 by 4 to get x by itself)
/4 /4
x = 3
Step-by-step explanation:
( y = 4x/5 + 2)
m1.m2 = -1
4/5.m2 = -1
m2 = -5/4
formula = y - y1 = m2 ( x - x1)
y - 3 = -5/4 ( x - 6)
y -3 = -5x /4 + 30/4
y = -5x /4 + 21/2
Answer:
$20.16
Step-by-step explanation:
First we need to find 12% of his current hourly rate, 12% is our decimal multiplier here so we use 0.12. In order to get 12% we need to multiply our decimal by $18 which is:
$18 × 0.12 = $2.16
Now let's add this 12% on top of his current hourly rate.
$18 + $2.16 = $20.16
And that's the final answer.
