Heather has 32 homework problems to complete by tomorrow. She completed 19 of them at school. Use the equation 19 + b = 32 to find b, the number of problems she must finish at home.

13 problems

Step-by-step explanation:

We have the equation, so all we must do is solve.

19+b=32

Subtract 19 on both sides

b=13

Hope this helps!

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
