Answer:
<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>
Step-by-step explanation:
1. Information given to us to solve the problem:
Marc's age today = 0
Marc's grandmother age today = 56
2. In how many years will Marc's grandmother be 5 times as Marc will be then?
x = Number of years when Marc's grandmother age will be 5 times as Marc will be then
Let's solve for x, this way:
5 times Marc age in x years = Marc's grandmother age in x years
5 (0 + x) = 56 + x
5x = 56 + x
5x - x = 56 (Subtracting x at both sides)
4x = 56
x = 56/4
<u>x = 14</u>
Let's prove that x = 14 is correct:
5 (0 + 14) = 56 + 14
70 = 70
We proved that x = 14 is correct
<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>
Answer:
B or C. See bottom of explanation.
Step-by-step explanation:
x+y=2 can also be said as:
2-x=y
so we have now described y in terms of x
replace 3y with 3(2-x) in the equation 3x+3y=6
3x+6-3x=6
take away six from both sides
3x-3x=0
this is 0=0
No solution. It could be any number. I am not sure if this counts as b or c, you decide. I am not really experianced in no solution/infinite solution problems
