ANSWER AS SOON AS POSSIBLE PLEASE! Jessica has $19. She buys 4 apples for x dollars each. Levi has $30 and buys 7 apples for x dollars each. Write an expression of how much money altogether they would have left?

This is the same as -11x+49

Explanation:

1 apple = x dollars

4 apples = 4x dollars, after multiplying both sides by 4

If Jessica buys 4 apples, then she spends 4x dollars.

Jessica has $19, so she'll have 19-4x dollars leftover after buying those four apples.

Similarly, Levi will have 30-7x dollars leftover when buying 7 apples for x dollars each.

Add up the leftover amounts to get...

(jessica's leftovers) + (Levi's leftovers)

(19-4x)+(30-7x)

19-4x+30-7x

(19+30)+(-4x-7x)

49-11x

This is the same as -11x+49 since you can think of 49-11x as 49+(-11x), and we can add two terms in any order we want.

An alternative viewpoint

Pool up Jessica's and Levi's amount they start with to get 19+30 = 49 dollars

Jessica buys 4 apples and Levi buys 7 apples. In total, this is 4+7 = 11 apples. At x dollars an apple, they spend 11x dollars. So they'll have 49-11x dollars leftover after buying those 11 apples.

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
