5. solve the problem by writing an inequality. a club decides to sell t-shirts for $12 as a fund-raiser. it costs $20 plus $8 per t-shirt to make the t-shirts. write and solve an                                   equation to find how many t-shirts the club needs to make and sell in order to profit at least $100. show your work?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
