Question

Help with Math I will medal!

Answer 1

Meg is 6 years older than Victor. Meg's age is 2 years less than five times Victor's age. The equations below model the relationship between Meg's age (m) and Victor's age (v):

m = v + 6
m = 5v − 2

Which is a possible correct method to find Meg's and Victor's ages?

Solve m + 6 = 5m − 2 to find the value of m.
Write the points where the graphs of the equations intersect the x axis.
Solve v + 6 = 5v − 2 to find the value of v.
Write the points where the graphs of the equations intersect the y axis.

Answer 3

Please, try to solve the equation:
v+6=5v-2

Answer 4

v=1

Answer 5

?? @Michele_Laino

Answer 6

I think v=2

Answer 7

I used mathway and the answer was v=1

Answer 8

please substitute v=1 into the equation, and check if you get an identity, if not try with v=2, tell me your answers ,please

Answer 9

Using 1 I got:
7=3

Answer 10

Using 2 I got:
8=8

Answer 11

then the right answer is?

Answer 12

v=2

Answer 13

Ok!, now calculate please the value of m, using the first equation, namely m=v+6, and write your answer

Answer 14

m=8

Answer 15

?

Answer 16

we got the ages of Meg and Victor.

Answer 17

Is it A B C OR D?

Answer 18

?

Answer 19

I think is the method that we have followed right now, because in the f we can find, from the equation m+6=5m+2, m=2. Nevertheless if I substitute m=2, for example in the first eqaution, namely m=v+6, I get v=-4, which is impossible because m and v are ages so they must be positive

Answer 20

oops...because in the first case we can find...

Answer 21

It is not any of the graphing correct?

Answer 22

sorry again from the equation m+6=5m-2

Answer 23

I think it might be C because if we know Victors age it will be easy to find Megs.

Answer 24

But it is also vise versa

Answer 25

yes

Answer 26

So I can click A or C?

Answer 27

I think C

Answer 28

furthermore we have worked with the assumption that both ages are greater than zero

Answer 29

Ok! Thanks!

Answer 30

Thanks!
