Harry went to the bakery with $50 to buy cupcakes and fruit tarts. One cupcake costs $3.50 and one fruit tart costs $3. Harry bo
mote1985 [20]

Answer:

28+3x\leq 50

Step-by-step explanation:

We are given the following in the question:

Cost of one cupcake = $3.50

Cost of one fruit tart = $3

Total money Harry have = $50

Harry bought 8 cupcakes and x fruit tarts.

We have to write the inequality giving relation between the total number of cupcakes and fruit tarts Harry can buy the amount of money he has.

Total cost of purchase =

= Total cost of cupcakes + Total cost of fruit tarts

=(8\times 3.50) + (x \times 3)\\=28 + 3x

Now, this total cost of Harry's purchase should be less than than equal to $50.

28+3x\leq 50

is the required linear inequality.

Answer:

Step-by-step explanation:

(3x + 1)/x = 1/(x -3)                Cross multiply

(3x + 1)(x - 3) = x                   Remove the brackets. Use FOIL

f:3x*x = 3x^2

o:3x*(-3) = -9x

i:1*x = x

L : 1 * - 3 = -3

FOIL: 3x^2 -9x +x - 3

FOIL: 3x^2 - 8x - 3

3x^2 - 8x - 3 = x                  Subtract x from both sides

3x^2 - 8x -x - 3 = 0             Combine

3x^2 - 9x - 3 = 0                 Factor

It's rather ugly. I had to use the quadratic equation

a = 3

b = - 9

c = - 3

x1 = 3.3

x2 = - 0.3
