Geez that is real complicated sorry I’m not sure just go with your gut
Answer:
B=25
Step-by-step explanation:
Simplify brackets
351 = y * 8 + 7
Regroup terms
351 = 8y + 7
Subtract 7 from both sides
351 - 7 = 8y
Simplify 351 - 7 to 344
344 = 8y
Divide both sides by 8
344/8 = y
Simplify 344/8 to 43
43 = y
Switch sides
<u>y = 43</u>
Mean = (19 +27 +25+21+44+22+45+34)/8 = 29.625≈30 years
Answer is 30.
