Answer:
A) 4
B) Mode is 5
C) 10.5
Step-by-step explanation:
A) 62+x/12
(62 + x) ÷ 12 = 5.5 ×12
62 + x = 66
×= 66-62
×=4
B) mode is the highest occuring no which is 5
C) mean has been given as 5.5; mean plus mode= 10.5
Remark
Drawing that diagram was a very good idea. If you can picture something happening, you are half way there. I tend to use a table, but the diagram will come to the same thing.
Olivia Dawn
Start 176 80
<u>Donate x x Subtract</u>
What's left 176 - x 80 - x
Equation
176 - x = 5*(80 - x) Olivia had 5 times as many books as Dawn did. Remove the brackets.
Solution
176 - x = 400 - 5x Add 5x to both sides
176 + 5x - x = 400 Combine terms on the left
176 + 4x = 400 Subtract 176 from both sides
4x = 400 - 176 Combine terms on the right.
4x = 224 Divide by 4
x = 224/4
x = 56 Answer
