For the first question, all you need to know is that the (amount you want) divided by (the amount of cards total) is the probability of getting the amount you want at random. for example, if there are 3 red marbles in a bag of ten marbles, you divide 3 by 10 (0.30) the probability of picking up a red marble is 30%. try adding up how many cards you want to pick up by the number of cards total.

Solve for x using cross multiplication. 2x + 2 = x-4 11 6 x = [?] Enter

kow [346]

you would cross multiply meaning 6(2x+2)=11(x-4) Then you distribute 6 so it would be 12x+12=11x-44 then you have to move the constant and the variable so 12x-11x= -44-12 so then the answer would be x = -56

Josie spent 4/7 of ten money in her purse on some books, and the rest of the money on 18 markers. Each marker cost $1.20. How mu

NeTakaya

Let's assume money in Josie's purse to begin with as 'x'

There are 18 markers

Each marker cost $1.20

so, we can find total cost of markers

Total cost of markers = ( total number of markers)*(price of each marker)

so, we can plug value

Total cost of markers is

$=18\times 1.20$
