X+y/3 =5 solve for x

2 answers:

5 0

(X+y)/3 = 5

(X+y) = 15

X = 15 - y

You can check by substituting the expression back into the original function and see whether or not the final value will still be the same.

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

m - 4m = -6

Step 2: Solve for m

Combine like terms: -3m = -6
Divide -3 on both sides: m = 2

Step 3: Check

Plug in m into the original equation to verify it's a solution.

Substitute in m: 2 - 4(2) = -6
Multiply: 2 - 8 = -6
Subtract: -6 = -6

Here we see that -6 does indeed equal -6.

∴ m = 2 is the solution to the equation.

What is the first step when estimating the quotient of 36.6 / 5

andre [41]

Answer:

I'm assuming you have 4 options, and if so, the answer is A.

Step-by-step explanation:

Rounding 36.6 off to 37 will make it easier to estimate the quotient when dividing by 5. For example, I can easily come up with a solution in my head when dividing 37 to 5 but it's harder for me to come up with a solution to 36.6.
