So for number one you would start with parentheses (-2 x 4) and that would get you -8 and then you would forget about the parentheses and drop everything else down and now the problem would be -8 x 3 and remember anytime you have a number by parentheses it’s multiplication and that dot by the parentheses also stands for multiplication so -8 x 3 would get you -24. You could also look at it as positive 8 x 3 and that would get you 24 and then you could just add that negative sign to the 24

Devante has a lunch account in the school cafeteria His starting balance at the beginning of the month is $35.50. The first wook

Alisiya [41]

Answer:

D the amount of money he pays for each lunch

Step-by-step explanation:

In each lunch Devante has, he pays 2,50 $ according to:

Money in t = t₀ he has 35,50 $ paid 3 lunches and spent

35,50 - 28 = 7,5

Then the cost of each lunch is 7,5 / 3 = 2,5 $

After that

bought 5 lunches and spent 28 - 15,5 = 12,50

Again 12,5 / 5 = 2,5 $

Now the model for the situation is a straight line with a slope 2,5

In an x , y cartesian system in which y is money in the account and x is the number of lunches, such a straight line will be

y = b - m*x ( b the intercept on y and m the negative slope)

y = 35,50 - 2,5*x

So answering the question is lyrics D the amount of money he pays for each lunch
