Answer:

Simplifying 9m + -3 + -7m = 0

Reorder the terms: -3 + 9m + -7m = 0

Combine like terms: 9m + -7m = 2m -3 + 2m = 0 Solving -3 + 2m = 0

Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right.

Add '3' to each side of the equation. -3 + 3 + 2m = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2m = 0 + 3 2m = 0 + 3 Combine like terms: 0 + 3 = 3 2m = 3

Divide each side by '2'. m = 1.5

Step-by-step explanation:

Hope this helps :)

Let

a------>is the tree’s age in years

we have that

-------> Javier's equation

we know that

The equation that represent the situation is equal to

Solve for a

Multiply by  both sides

System of equations, special case infinitely many solutions?????
Mashcka [7]

One possible system is

1x + 3y = 4

2x + 6y = 8

Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.

In other words, the second equation is the result of multiplying both sides of the first equation by 2.

1x+3y = 4

2*(1x+3y) = 2*4

2x+6y = 8

Effectively the two equations in bold are the same which produces the same line. The two lines overlap perfectly to intersect infinitely many times. An intersection is a solution.

castortr0y [4]

Answer:

70.6

Step-by-step explanation:

The mean is the average of a set of numbers.

To find it, add up all the terms and divide it by the number of terms.

70 + 67 + 79 + 66 + 64 + 80 + 64 + 75 = 565

565 / 8 = 70.625

Rounding this to the nearest tenth, we get an answer of 70.6
