Answer:
262
Step-by-step explanation:
If x is the first integer, then x+1 is the second, x+2 is the third, and so on. Meaning the 7th term in the list is x+6.
x + x + 6 = 518
2x = 512
x = 256
The first integer is 256, so the last integer is 262.
Ya, can't help if you don't show the questions.

Answer:
x = 15.33
Step-by-step explanation:
3y is equal to 2x + 13. The reason why is because they are corresponding angles, (right next to each other). From there, you would have to substitute y into 3y. The equation should look like: 3(23) = 2x + 13. All that is left is to solve for x.
Here you go, hope this kinda helps you out :)
