Select the correct answer. A mistake was made in the steps shown to simplify the expression. Which step includes the mistake?
9/2+ 3(4 – 1) – 7 + 23
Step 1: = 9/2 + 3(3) – 7 + 23
Step 2: = 9/2+ 3(3) — 7 +8
Step 3: =
15/2 (3) – 7 + 8
Step 4: =
= 45/2 - 7+8
Step 5: = 31/2+ 8
Step 6: = 47/2

A. Step 5
B. Step 3
C. Step 4
D. Step 1

STEP 3 is wrong

Step-by-step explanation:

9/2+ 3(4 – 1) – 7 + 2^3

PEMDAS

Parentheses

Step 1: = 9/2 + 3(3) – 7 + 2^3

Exponents

Step 2: = 9/2+ 3(3) — 7 +8

Multiply and divide

Step 3: =15/2 (3) – 7 + 8  ADDED not multiply

Step 4: = 45/2 - 7+8

Step 5: = 31/2+ 8

Step 6: = 47/2

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
