Determine the missing number 420 + = 670 basically 420 + what = 670 so what equals 670 but has to include 420 P. S please note this is 5th grade please don't put all of this x=y i just need a 5th grade explanation

The answer is 250.

Step-by-step explanation:

Hello! This is a simple subtraction matter. All order-of-operations are opposites (multiplication and division, and addition and subtraction.) This means that since we're presented with a case where 420 + something = 670, the opposite is 670 - 420 = something.

If we compute some simple calculations, 670 - 420 = 250.

There's your answer :)

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.

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.
