Answer:

357

Step-by-step explanation:

Create an equation:

Let x represent your age.

1114 - 2x = 400

Solve for x:

1114 - 1114 - 2x = 400 - 1114

-2x = -714

-2x / -2 = -714/-2

x = 357

hope this helps. p.s. i really need brainliest :)

Answer:

They are equal

Step-by-step explanation:

Given

$\frac{3}{27}\ and\ \frac{1}{9}$

Required

Determine if they are equal

We start by equating both:

$\frac{3}{27} = \frac{1}{9}$

Cross Multiply

$3 * 9 = 1 * 27$

$27 = 27$

The solution is??? 3m-2/3-2m+1/4=2/12

zloy xaker [14]

3·m - 2/3 - 2·m + 1/4 = 2/12

m - 2/3 + 1/4 = 2/12

m = 2/12 - 3/12 + 8/12

m = 7/12
