X=18
Because you would add 2 to both sides so it would be x=16+2 which equals 18

Lerok [7]

Answer:

2244 cm

Step-by-step explanation:

The first first thing we must do is find the LCM of the following numbers

(51; 68) = 204.

This means that the first time they coincide is at 204.

Now, since his steps always coincide after 204

In Nick's case

Nick's 204 ÷ 51 = 4th step

and in the case of the father

204 ÷ 68 of his father = 3rd step.

Which means that in the 204 cm distance, there will be a total of 6 foot steps, except in the first 204 cm when your "initial" step is counted.

Replacing these values we have that the total distance will be:

67-1 (initial step) / (6 * 204) = 2244 cm

Answer:

15x-6y=48

Step-by-step explanation:

So we have the system of equations:

5x-2y=16\\15x-7y=51

And we want to multiply the first equation by some constant such that the resulting equation matches the coefficient of [x] in the second equation.

We can see that the coefficient of x in the second equation is 15.

So, to match 15, we must multiply the first equation by 3. So:

3(5x-2y)=3(16)

Multiply:

15x-6y=48

And we're done!

Sedbober [7]

Hello from MrBillDoesMath!

Answer:

12 m n^2

Discussion:

3m * 4 * n * n  =                       => 3* 4 = 12

12 m * n * n                              => as n*n = n^2

12 m n^2

Thank you,

maks197457 [2]
1/3x + 2 = 4/3x - 5
2 + 5 = 4/3x - 1/3x
7 = x

y = 1/3(7) + 2
y = 7/3 + 2
y = 7/3 + 6/3
y = 13/3

solution is : (7,13/3) <=
