X = 9 . to find this out, you need to plug in the given info into a^2 + b^2 = c^2 .. so we have a^2 + 6^2 = 117. Which is a^2 + 36 = 117. so we need to get a by itself. to do so, subtract 36 from both sides to get a^2 = 81. Lastly, we need to find the square root of both sides. the square root of a^2 is a, and the square root of 81 is 9. which leaves us with a = 9
It would take him 9 hours to drive 522 miles since if you divide 638 with 11 you would get 58 and if you divide 522 with 58 you'll get 9.
Answer:
x = -24/5
Step-by-step explanation:
2x – 3 + 3x = – 27
Combine like terms
5x -3 = -27
Add 3 to each side
5x-3+3 = -27+3
5x = -24
Divide each side by 5
5x/5 = -24/5
x = -24/5
9(3x - 16) + 15 = 6x - 24
First distribute 9 to 3x and -16.
27x - 144 + 15 = 6x - 24
Combine like terms. (-144 + 15)
27x - 129 = 6x - 24
Get the variable, x, on one side of the equation. You can do this by subtracting 6x from both sides.
21x - 129 = -24
Add 129 to both sides to isolate x.
21x = 105
Divide 21 off of both sides to find the value of x.
x = 5
You can plug x into the equation to check your answer.
9(3 x 5 - 16) + 15 = 6(5) - 24
6 = 6
