Answer:
Simplifying
7x + -2(x + 1) = 6x + 14
Reorder the terms:
7x + -2(1 + x) = 6x + 14
7x + (1 * -2 + x * -2) = 6x + 14
7x + (-2 + -2x) = 6x + 14
Reorder the terms:
-2 + 7x + -2x = 6x + 14
Combine like terms: 7x + -2x = 5x
-2 + 5x = 6x + 14
Reorder the terms:
-2 + 5x = 14 + 6x
Solving
-2 + 5x = 14 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
-2 + 5x + -6x = 14 + 6x + -6x
Combine like terms: 5x + -6x = -1x
-2 + -1x = 14 + 6x + -6x
Combine like terms: 6x + -6x = 0
-2 + -1x = 14 + 0
-2 + -1x = 14
Add '2' to each side of the equation.
-2 + 2 + -1x = 14 + 2
Combine like terms: -2 + 2 = 0
0 + -1x = 14 + 2
-1x = 14 + 2
Combine like terms: 14 + 2 = 16
-1x = 16
Divide each side by '-1'.
x = -16
Simplifying
x = -16
Step-by-step explanation:
18 is 15% of 120. Because 15% = 0.15 and 15% of 120 is 120x0.15= 18.
Answer:
100
Step-by-step explanation:
She wants to average 85, so adding ALL three of her scores, divided by 3 needs to equal 85.
(75 + 80 + x)/3 = 85
Times by 3.
75 + 80 + x = 255
155 + x = 255
subtract 155.
x = 100
She needs 100 on the third test.
Answer:
7.81 u
Step-by-step explanation:
<u>Given :- </u>
- Two points (3,3) and (-2,-3) is given to us.
And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,
D = √{(x2-x1)² + (y2-y1)²}
D =√[ (3+2)² +(-3-3)²]
D =√[ 5² +6²]
D =√[ 25 +36]
D = 61
D = 7.81
<h3>Hence the distance between the two points is 7.81 units .</h3>
