Answer:
Yes that's true
Step-by-step explanation:
My answer-
Simplifying
5x + -14 = 8x + 4 Reorder the terms:
-14 + 5x = 8x + 4
Reorder the terms:
-14 + 5x = 4 + 8x Solving
-14 + 5x = 4 + 8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8x' to each side of the equation.
-14 + 5x + -8x = 4 + 8x + -8x
Combine like terms: 5x + -8x = -3x
-14 + -3x = 4 + 8x + -8x
Combine like terms: 8x + -8x = 0
-14 + -3x = 4 + 0
-14 + -3x = 4
Add '14' to each side of the equation.
-14 + 14 + -3x = 4 + 14
Combine like terms: -14 + 14 = 0
0 + -3x = 4 + 14
-3x = 4 + 14 Combine like terms: 4 + 14 = 18
-3x = 18 <span>
Divide each side by '-3'.
x = -6
Simplifying
x = -6

Answer:
D. 60%
Step-by-step explanation:
Of the 65% who study either time, 47% study on weekends. That means 65%-47% = 18% study on weeknights only.
The fraction who study on weeknights is the total of the fraction who study on weeknights only (18%) and the fraction who study on weeknights and weekends (42%). That total is ...
18% +42% = 60% . . . . fraction who study on weeknights

It can be helpful to draw yourself a Venn diagram.
When we add two equations, it's important to <em>combine like terms</em>
<u>x's with x's </u>
<u>y's with y's </u>
<u>and constants with constants</u>
2x + 5x = 7x
3y + (-y) = 2y
-5 + -12 = -17
Let's put <em>everything together </em>for a final equation
7x + 2y - 17 = 0
or
7x + 2y = 17
