Answer:
You must order the operations in the way that it unfolds in the explanation;:
Step-by-step explanation:
(25 x 9) +75 + 50+ 9 x ( 3 + 1)
When performing the operations we have the following results:
(25 x 9) =225 +75= 300+50 = 350+9 = 359 x (3+1 )
Now we must solve the following: 359 x (4) = 386
X is the undefined variable hope it helps
Solution:
we are given that
If G is the midpoint of FH, it mean that

we are also given that

So we can write

So 
We know that 3/10*20=6 students are eating salads.
We also know that 3/5*20=12 students are eating sandwiches.
Assuming each person only eats one thing, there are 20-12-6=2 students eating lunches other than salads or sandwiches.
