Answer:
x = 4.25
Step-by-step explanation:
1. distribue the -5 on the left side of the equal sign by multiplying it with 2x and -9 inside the brackets. Do the same with the negative sign and the -6x and 10 in the brackets on the right side of the equation. this should make:
17 - 10x + 45 = 6x - 10 + 4
2. Combine like terms on both sides of the equal sign. Add 17 and 45, and add -10 and 4 to make:
62 - 10x = 6x - 6
3. Bring like terms onto the same side. You can either bring the 62 to -6, which would make 62 negative, or bring -6 to 62, making the 6 positive. Do the same with -10x and 6x. It should make:
68 = 16x OR -68 = -16x
4. Divide both sides by 16 or -16, depending on which option you went with.
68/16 = 16x/16 OR -68/-16 = -16x/-16
This gives:
4.25 = x
Answer= X>3
5x>15
Divide both sides by 5x
5x will cancel with 15. You get 3
So, x>3
Answer:
arithmetic sequence formula: first term + (n - 1)common difference
9 + (n - 1)-2
9 + -2n + 2
= -2n + 11
they took my first answer off, so i came back. but honestly thank you for the points. have an amazing day!
