Evalulate: 3x(2+6) divided 4 - 2

Step-by-step explanation:

3x(2+6):(4-2)

First find answer of equlation of ()

which means 3x8 =24

and then 4-2=2

and 24:2 = 12

3*(2 + 6) ÷ 4 - 2 = 12.

Step-by-step explanation:

First, add 2 + 6. They are always first if they have parenthisities.

2 + 6 = 8.

then, multiply 8 by 3.

8*3 = 24

then, subtract 2 by 4.

4 - 2 = 2. This is always recommended after multiplication.

finally, divide 24 by 2.

24 ÷ 2 = 12.

Hope this helps!

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
