The value of sallys caravan decreased by x% in the third year. At the end of the third year the value of sallys caravan was £16,500. Work out the value of x
Answers
The value of x is 100 - 1650000/y where the initial value of the Sally's caravan be represented by y
How to work out the value of x?The given parameters are
New value = £16,500
Rate of decrease = x%
Let the initial value of the Sally's caravan be represented by y
So, we have the following equation
Initial value * (1 - Rate of decrease) = New Value
This gives
y * (1 - x%) = 16,500
Divide both sides of the equation by y
So, we have
1 - x% = 16500/y
This gives
x% = 1 - 16500/y
Multiply through by 100
x = 100 - 1650000/y
Hence, the value of x is 100 - 1650000/y where the initial value of the Sally's caravan be represented by y

Triangle BCD has the following side lengths: BC = 60, CD = 50
Triangle RST has the following side lengths: RS = 11x-4, ST = 70
What is the value of x? (put just the number in the first box)
What is the length of side RS? (put just the number in the second box)
Answers
The value of x is 11 and the length of side RS is 117
How to determine the value of x?The given parameters are
BC = 60 and CD = 50
RS = 11x - 4 and ST = 70
Express as a ratio
BC : CD = RS : ST
So, we have
60 : 50 = 11x - 4 : 70
Express as fraction
So, we have
60/50 = (11x - 4)/70
Cross multiply
So, we have
50 * (11x - 4) = 70 * 60
Divide both sides by 50
So, we have
11x - 4 = 84
This gives
11x = 88
Divide both sides by 11
So, we have
x = 11
Substitute x = 11 in RS = 11x - 4
RS = 11 x 11 - 4
Evaluate the product and the sum
RS = 117
Hence, the value of x is 11 and the length of side RS is 117
