The difference of the grandson's age in years and the grandfather's age in years is 77. Therefore, the age of the grandson is 7 years.
<h3>How to use equations to find the age?</h3>
A grandson's age in months is equal to his grandfather's age in years.
Recall,
12 months = 1 year
Hence,
let
x = age of grandson in month
It is the same age in years for the grandfather.
Therefore,
x = age of grand father in years
The difference of the grandson's age in years and the grandfather's age in years is 77. Therefore,
x - x / 12 = 77
12x - x/12 = 77
11x / 12 = 77
cross multiply
11x = 924
x = 924 / 11
x = 84
Therefore, the grandson age in in years is 84 / 12 = 7 years.

Answer:
30/-11
Step-by-step explanation:
u just have to flip it good luck : )
A plot of the points quickly reveals the vectors to be parallel.
11. 8.73 x 6.01....estimation : 9 x 6 = 54
13. 197.4 x 2.85...estimation : 197 x 3 = 591
15. 479.2 x 3.2...estimation : 479 x 3 = 1437
all I did was round the numbers to the nearest whole number, then just multiplied
