Answer:

Last equation 350 - 170 - 120 = r

Step-by-step explanation:

So if she ordered 350, and we already know 170 + 120 for black and blue pens. So we add 170 and 120 to get 290. So we subtract 290 from 250 and get 60. So the equation is 350 - 170 - 120 = r. Brainliest please!

Opposite sides are corresponding (AB = DC).

Opposite angles are corresponding (D = B).

Consecutive angles are supplementary (A + D = 180°).

If one angle is right, then all angles are right.

Jennifer has run many marathons and keeps track of all of her finishing times. At a marathon last month, she finished in 350 min

suter [353]

Answer:

16%

Step-by-step explanation:

406 / 350 = 1.16

406 is 116% of 350

so 350 + 16% is 406

because 350 * 0.16 = 56

56 is 16%

350 + 56 = 406
