Answer:
John takes 20 steps in 10 yards.
Step-by-step explanation:
1 yard = 36 inches
10 yards = 36 x 10 = 360 inches
Since John's step covers 18 inches, divide 360 by 18.
360/18 = 20 steps
Answer:
Yes
Step-by-step explanation:
Because they are reflecting over a x intercept
5.62 would be 5 62/100 then you can simplify the fraction down
62/100 - 31/50
5 31/50

Step-by-step explanation:
5x + 2x
that is the same as (5 + 2)x
and that is the same as (7)x = 7x
so, for the second part of the problem we are actually comparing
7x
and
7x - 1
there is therefore no way for the two expressions to deliver the same value for the same x.
the values of 7x are always larger by one than the values of 7x - 1
so, e.g.
x = 1
5×1 + 2×1 = 5 + 2 = 7
7×1 - 1 = 7 - 1 = 6
x = 2
5×2 + 2×2 = 10 + 4 = 14
7×2 - 1 = 14 - 1 = 13
x = 3
5×3 + 2×3 = 15 + 6 = 21
7×3 - 1 = 21 - 1 = 20
x = 4
5×4 + 2×4 = 20 + 8 = 28
7×4 - 1 = 28 - 1 = 27
x = 5
5×5 + 2×5 = 25 + 10 = 35
7×5 - 1 = 35 - 1 = 34
