Rearrange the 2nd equation

-36a-24b-16c

divide the whole thing by 4 and you'll get
-9a-6b-4c

you'll realize it looks the same as your first equation except that all the + has become minus so the answer will be -7 instead for your new equation
-9a-6b-4c=-7

multiply the whole thing by 4 and you'll get
-36a-24b-16c = -28

so the answer you want is -28

Irina18 [472]

Answer:

1.2 + 3x6 = 19.2

2.4(8-3) = 11.25

3.7 + 8 (3 + 2) = 43.7

4(6 - 5) + (8 x 10) = 84

Hope this helps!

Have a great day

PLEASE HELP! THIS IS DUE TOMORROW MORNING!!!!! I KNOW IM STUPID BUT I NEED HELP!!! lol

From Walmart, you have to buy at-least= 50/8 = 6.25 = 7 [round-off to larger direction value ]
So, it would cost = 7 * 2.99 = $20.93

From Sam's club, you have to buy at-least= 50/12 = 4.16 = 5 [round-off to larger direction value ]
So, it would cost = 5 * 3.19 = $15.95

In short, Sam's club offers the better deal.

Now, we can spend our minimum expense, by buying 3 pcs. of bun from Sam's club and 2 from walmart.
In that case, it would cost = 3*3.19 + 2*2.99 = $15.55

Hope this helps!
