Answer:
x = 10
Explanation:
Using Pythagoras Theorem:
Solve:
8² + 6² = x²
x² = 64 + 36
x² = 100
x = √100
x = 10
Answer: x = -1
Step-by-step explanation:
- 2x-3= - 4x+9
- 2x+4x = -9 + 3
- 6x = -9 + 3
- 6x/6 = -6/6
- x = -1
The answer is 12x+4 and 2(6x+2)
Hope it helps.
Answer:
45
Step-by-step explanation:
Let the number be X.
So 2/3 of a number would be (2/3)x and 1/5 of the same number would be (1/5)x. Therefore, (2/3)x+(1/5)x=39. Next, you combine like terms by converting the fractions: (10/15)x+(3/15)x=39. Now, you add the fractions. (13/15)x=39. Lastly you divide both sides by 13/15 or multiply both sides by 15/13. x=45. That number would be 45.
<u>If you would like to check</u>, you would do 2/3(45) or 90/3 which is 30 and do 1/5(45) or 45/5 which is 9. 30+9=39
