Step-by-step explanation:
so first convert it into an algebraic equation
4 - ⅛w = 16
⅛w = 16-4
⅛w = 12
w=12÷
w=12×8=96
check: 4 - ⅛(96)=4-12=-8
-8<16 (-8 less than 16)

Colin and Dan win some money and share it in the ratio 4:5. Colin gets £52. How much did they win in total?
1 answer:
Answer:
They won £117 in total.
Step-by-step explanation:
There are two methods to solve the question.
- Finding the total amount directly
- Finding Dan's share and adding it to Colin's share
It is given that the ratio is 4:5
Let x be the share of Dan
The ratio between Colin and Dan's share will be 52/x and it should simplify to 4/5
The total amount will be:
Hence,
They won £117 in total.

The total length of the segment AC is the sum of AB and CB, which gives, CB = 9
<h3>How can the length of CB be found?</h3>The given parameters are;
- AC = 17
- AB = 32 + 3•x
- CB = 57 + 6•x
Required: <em>CB</em>
Solution:
AC = <em>AB + CB</em> by segment addition property
Therefore;
AC = 17 = 32 + 3•x + 57 + 6•x = 89 + 9•x
17 = 89 + 9•x
CB = 57 + 6•x = 57 + 6 × (-8) = 9
Therefore;
- <u>CB = 9</u>
