Hector used the following clues to find an unknown 3 digit number. my tens digit is one less than my hundreds digit. my hundreds digit is 7. the sum of my ones digit and my tens digit is 8. what is the number?

762

Step-by-step explanation:

Let,

abc is an unknown 3 digit number in that

a = hundredth digit

b = tenth digit

c = ones digit

Given,

a = 7

c + b = 8

b = a - 1

So we known,

a = 7 and b - 1 = a such that b = 7 - 1 which make b = 6

Since b = 6 and c + b = 8 then c + 6 = 8  which make  c = 2

And the number is abc or 762

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.

16.80 times .20= 3.36
