Before we start sticking a bunch of x's in these things, let's remember what they are.
Look at a few examples:
| 5 | = 5
| 0 | = 0
| -3 | = 3
So...

Answer:
B & C
Step-by-step explanation:
I'm not sure if you can have two answers but both of them are linear. A And D aren't because they have absolute value
Answer:
Loose sweets are of better value
Step-by-step explanation:
<u>Packed</u>
120 g = £1.49
price per gram = £1.49/120= £0.0124
<u>Loose</u>
100 g = £0.89
price per gram= 0.89/100= £0.0089
Comparing prices per gram, we can see loose sweets cost less (0.0089<0.0124), so is better value
45÷5=9 is the equation that helps her find an equal share and 45÷9=5 is the equation that proves her thinking is correct
5 trumpet players
let s represent saxophone players and t trumpet players
thus t = s - 10 → ( 10 less than saxophone players)
also s = 3t = 3( s - 10)
solve s = 3( s - 10)
s = 3s - 30
subtract s from both sides of the equation
0 = 3s - s - 30
0 = 2s - 30
add 30 to both sides
30 = 2s
divide both sides by 2
= s ⇒ s = 15
number of trumpet players = 15 - 10 = 5
