Answer:
11
Step-by-step explanation:
Do kcf (keep,change,flip)
First, covert 2 3/4 into an improper fraction
Then after you do that you get 11/4
so you do the equation 11/4 ÷ 1/4
when you do kcf it would be 11/4 × 4/1=
11/4×4/1=44/4 simplify divide both by 4 = 11
Here you have two sets of parentheses. Order of operations rules (PEMDAS) require that you perform any operations that are presented within parentheses first. Mult and div come next, and then any addition and/or subtraction.
We must perform the addition 4+8 first; the correct outcome is 12. Then we have:
16 • [(12)÷4]
We must perform the operation inside brackets first:
16*[3] = 48 (answer)
Given equation is ,
To find x, first add - 5 on both sides
Multiply both side by 4 to isolate x
Now to find x, divide both side by 1
x = 8
So option 3 is the answer
