Answer:

x = 12

Step-by-step explanation:

Given a tangent and a secant from an external point to the circle, then

The square of the tangent is equal to the product of the external part and the entire secant, that is

x² = 6(6 + 18) = 6 × 24 = 144 ( take the square root of both sides )

x = $\sqrt{144}$ = 12

soldi70 [24.7K]

Answer: 6

Step-by-step explanation:

Let x represent the number of plates bought for $6

Let y represent the Total number of plates bought = x + 1

Remember that Mrs. Lim bought another plate for $18

Total cost ÷ Total plates = Average Cost

$\dfrac{6x+18}{x+1}=8\\$

6x + 18 = 8(x + 1)

6x + 18 = 8x + 8

18 = 2x + 8

10 = 2x

5 = x

y = x + 1

= 5 + 1

= 6

insens350 [35]

Answer:

$13.5

Step-by-step explanation:

Given data

We are given that the tax per CD is $1.30

Hence for the 3 CDs the total tax = 3*1.3= $3.9

Also, the cost of the three CDs before tax = 44.4-3.9

=$40.5

Hence the cost of each CD before tax is

=40.5/3

=$13.5
