The answer is A. Put the 6 for n in 0.009
2 is the unknown number.
Let x be the unknown number.
2x + 19 = 23
2x = 23 - 19
2x = 4
2x/2 = 4/2
x = 2
to check:
2(2) + 19 = 23
4 + 19 = 23
23 = 23
Answer:
Simplifying
2(x + 3) + 3x + -10 = 0
Reorder the terms:
2(3 + x) + 3x + -10 = 0
(3 * 2 + x * 2) + 3x + -10 = 0
(6 + 2x) + 3x + -10 = 0
Reorder the terms:
6 + -10 + 2x + 3x = 0
Combine like terms: 6 + -10 = -4
-4 + 2x + 3x = 0
Combine like terms: 2x + 3x = 5x
-4 + 5x = 0
Solving
-4 + 5x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 5x = 0 + 4
Combine like terms: -4 + 4 = 0
0 + 5x = 0 + 4
5x = 0 + 4
Combine like terms: 0 + 4 = 4
5x = 4
Divide each side by '5'.
x = 0.8
Simplifying
x = 0.8
Step-by-step explanation:
Make is so that all X's are on one side and the constant numbers on the other side. Which creates the equation 0 = 0 or no solution
Answer:
C. 85 degrees
Step-by-step explanation:
Step 1: Set up equation
x + 57 + 96 + x = 131
Step 2: Solve for <em>x</em>
2x + 153 = 131
2x = -22
x = -11
Step 3: Find m∠RQU
m∠RQU = 96 + <em>x</em>
m∠RQU = 96 - 11
m∠RQU = 85°
