<em>"Myra should have multiplied 4.5 and 2.1 first."</em>

How to evaluate an expression?</h3>
Here we want to evaluate the expression:
-31.7 + 4.5*x
in x = 2.1
This just means that we need to replace x by 2.1 in the given equation.
Now, what Myra does is:
-31.7 + 4.5*2.1 = -27.2*2.1
So she took the sum between -31.7 and 4.5 first, this is her mistake, you only would do that if the expression was:
(-31.7 + 4.5)*2.1
But in our expression:
-31.7 + 4.5*2.1
The first thing you need to solve is the product in the second term, so we get:
-31.7 + 4.5*2.1 = -31.7 + 9.45 = -22.25

Answer:
B
Step-by-step explanation:
He found out how many people who play 2+ instruments are 8th graders rather than how many 8th graders play 2+ instruments.
Make bottom numbers same
find least common multipules of 8,12,4 and 3
8=2 times 2 times 2
12=2 times 2 times 3
4=2 times 2
3=3
lcm=2 times 2 times 2 times 3=24
5/8 times 3/3=15/24
5/12 times 2/2=10/24
3/1 times 24/24=72/24
1/4 times 6/6=6/24
2/3 times 8/8=16/24
we now have
15/24-10/24(72/24-6/24)+16/24
pemdas
simplify parenthasees first
72/24-6/24=66/24
now we have
15/24-10/24(66/24)+16/24
multiply
15/24-660/576+16/24
make same bottom number
15/24 times 24/24=360/576
16/24 times 24/24=384/576
360/576-660/576+384/576
84/576
7/48
answer is 7/48
