Question

I need help pleaseeee

Answer 1

Answer:

21.75

Step-by-step explanation:

Plugging in the variables, you'd get 24 - (20-4) over (4 + 4). Add the contents of the parenthesis and you'd get 24 - (18)/(8). You'd divide, and get 24- 2.25, or 21.75.

If you aren't supposed to simplify on this assignment, it would probably be 24 - 18/8, or if you use fractions 21 and 3/4.

Answer 2

22

Step-by-step explanation:

first you would substitute the numbers with the values and solve.

12(2)- 4(5)-4/4+4

24-20-4/8

24-16-8

24-2

22

the slash means a fraction
