Here I'll Simplify it to show the work.
You need PEMDAS
9(2*2+4÷2)
9(4+4÷2)
9(8÷2)
9(4)
9(4) = 9 × 4 = 36
The Answer is 36.
Answer:
15) 37 16) -5x+13=-112, x=25 23) l=38, w=19
Step-by-step explanation:
15) l=5w+2, 2l+2w=88
2(5w+2)+2w=88
12w+4=88
w=7, l=37
16a) -5x+13=-112
16b) x=25
23) l=2w, 2l+2w=114
2l+l=114
l=38, w=19

Answer: 2/3</h3>
============================================
Work Shown:

When dividing fractions, you flip the second fraction and multiply (step 2).
Note in the last step, the 7's cancel out.
Answer:
B. 1.82n
Step-by-step explanation:
Expression given: n + n - 0.18n
Adding n+n gives '2n'
then subtracting 0.18n from 2n gives= 1.82 n
Therefore,
n + n - 0.18n=0.18n
