Answer:

-6

Step-by-step explanation:

We use PEMDAS to solve this,

so P stands for parentheses, so that's where we start.

We first, square the innermost parentheses with the exponent which is the E in PEMDAS, then then the outer parentheses

-12/3*(-8+16-6)+2

-12/3*(2)+2

Now we divide as in Division in PEMDAS.

-4*2+2

Now we multiply as in Multiplication in PEMDAS.

-8+2

Now we add as in A for Addition

-6

In PEMDAS, Multiplication doesn't always come before division, and same for addition and subtraction.

What the value of 4x+1/2 y 2.what is the value of the expression above when x = 2 and y = 3?
arlik [135]
Hoi!

To solve this, first plug in the values for x and y.

4x + \frac{1}{2}y

Turns into...

4(2) +  \frac{1}{2}(3)

Now that we've got the values plugged in, let's solve.

4 × 2 = 8

8 +  \frac{1}{2}(3)

\frac{1}{2} × 3 = 1 \frac{1}{2}

8 + 1 \frac{1}{2} = 9 \frac{1}{2}

9 \frac{1}{2} is your answer. :)
