John and Nadim do the math homework together. When they find 9 - (-8), they get different answers. John claims the difference is 17. Nadim claims the difference is -1. Who is correct?

John is correct

Step-by-step explanation:

The rule in mathematics states that

- × + = -

+ × + = +

- × - = +

Hence, for the homework,

9 - (- 8) = x

9 + 8 = 17

Therefore, John is correct and Nadim is incorrect.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
