Answer:
x = 9
Step-by-step explanation:
1/4(8x+12) =21
1/4 * 8x = 2x
1/4 * 12 = 3
2x + 3 = 21
21 - 3 = 18
2x = 18
18/2 = 9
x = 9
Answer:
Angle 1: 52 degrees
Angle 2: 128 degrees
Step-by-step explanation:
Angle 1 = x
Angle 2 = 2x + 24
Supplementary angles are two angles that add up to 180 degrees.
x + 2x + 24 = 180
3x + 24 = 180
3x = 180 -24
3x = 156
x = 52
Check:
Angle 1: x = 52
Angle 2: 2x + 24
2(52) + 24
104 + 24 = 128
128 + 52 = 180
It can be less than, more than or equal to zero
Answer:
The answer is the last option, D.
Step-by-step explanation:
A function with one solution can be added and have a variable and a constant leftover. The variables in the other three options cancel each other out, so none of them have one solution. The first and third equations have no solutions, and the second has infinitely many solutions. The fourth option has only one variable cancel out and still has a constant on the other side of the equation. The fourth option is correct.
117.69615 is correct. it would be 118 to the nearest whole number
