If you would like to solve for x: 3x - 24 = 81, you can do this using the following steps:
<span>3x - 24 = 81
</span>3x = 81 + 24
3x = 105
x = 105 / 3
x = 35
The correct result would be 35.
Answer:
12
Step-by-step explanation:
This question means 3/(1/4). The rule for division of fractions is invert the denominator and multiply. 3/(1/4) = 3 * 4 = 12. Another way to think of it is to imagine you have 3 pies each divided into quarters.
4x - 2 = 2x + 8
2x -2 = 8
2x = 10
x = 5
4(5)-2 = 2(5)+8
20-2 = 10+8
18 = 18
Answer:
22.5
Step-by-step explanation:
ANSWER: x = 130°
EXPLANATION: You must add given angles and then subtract from 180°.
