Solving for x is easier if
First, remove the parenthesis.
-3(x-1) = 3(4-x)-9
-3x + 3 = 12 - 3x - 9
Next, group the numbers with x on the left side and the rest on the right side.
-3x + 3x = 12 - 9 - 3
0 = 0
So, x has no solution.
20% of 150 is 30
Change the percentage into a decimal by dividing it over 100:
20 / 100 = 0.2
Multiply:
0.2 × 150 = 30
Answer:
-6 and -7
Step-by-step explanation:
The best explanation is on a number line, -6.2 lies about 1/4 away from -6, and -6.2 lies .8 away from -7.
Best of Luck to you!
<span>If a ray lays in a plane, assuming it is contained by the plane, this results in a line intersection plane-line relationship. This means all the points of the ray are also in the plane.</span>
Answer:
x = -1
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-2*(x-5)+7-(19)=0
Step by step solution
Equation at the end of step 1
((0 - 2 • (x - 5)) + 7) - 19 = 0
Pulling out like terms
3.1 Pull out like factors :
-2x - 2 = -2 • (x + 1)
Equation at the end of step
3
-2 • (x + 1) = 0
STEP
4
Equations which are never true
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x+1 = 0
Subtract 1 from both sides of the equation :
x = -1
