Answer:

12

Step-by-step explanation:

If z = 6 and d = 7, we can fill them in the variables. Let's rewrite the expression:

-3([ 2 × 6 ] - [ 8 × 7])

Let's start with the stuff inside the brackets. 2 × 6 minus 8 × 7. We know 2 × 6 = 12, and 8 × 7 = 56.

Then we have -3( 12 - 56 )

We then have to do 12 - 56, which gets us -44.

We now have -3( -44 ) or -3 × (-44)

-3 × (-44) = 12

Thus, we get our final answer of 12.

Hope this helped!

Answer:

$6.50 per bag of popcorn

Step-by-step explanation:

let a bag of popcorn be represented by p and a candy bar be b

28p + 40b= $282

17p + 20b= $160.50

this is an example of stimatanelous equations

so you have to double the second equation to give 34p + 40b =$321

subtract the equations to give one

6p =$39

divide $39 by 6 to give the value of one bag of popcorn = $6.50

URGENT PLEASE HELP !!!!!
Mumz [18]

Answer:

Let P represent the number of pies sold and J represent the number of juices sold.

a)

The first equation for the sum of the sales:

P + J = 79

P = 79 - J

Next, for the sum of the amounts earned:

1.65P + 1.36J = 118.17

Substituting P,

1.65 (79 - J) + 1.36J = 118.17

J = 42

Using this value of J,

P = 79 - 42

P = 37

b)

Mr. Sanchez's class earned: 1.65 x 37 = $61.05

Mr. Kelly's class earned: 1.36 x 42 = $57.12

So Mr. Sanchez's class earned more money.

c) Mr. Sanchez's class earned:

61.05 - 57.12

= $3.93 more than Mr. Kelly's class

Step-by-step explanation:
