Alright here we go...

<u>(-18) + (-15) - 23</u>

-33 - 23

= -56

<u>15-18+23</u>

-3 + 23

= 20

so I don't know how you want me to compare it but,

(-18) + (-15) - 23 < 15-18+23

A combo meal and a salad cost $12
lubasha [3.4K]

Answer:

The cost of a combo meal is $8 and a salad is $4.

Step-by-step explanation:

You have to form simultaneous equations with the given informations. Let combo meal be m and salad is s :

m + s = 12 -  -  - (1)

2m + s = 20 -  -  -  (2)

Next, you have to solve these equations :

(2) - (1)

2m + s - m - s = 20 - 12

m = 8

sub  \: \: m = 8  \: \: into \:  \: (1)

(1)⇒

8 + s = 12

s = 4
