18/3=6 you do this because you assume all the cubes are the same. Also because they form a cube they are proportionate to each other.
Answer:
Mia had $1554.84
Step-by-step explanation:
100% = $2468
1% = $ 24.68
100 - 37 = 63%
63 % = 63 × $24.68
= $1554.84
3x-y=6
y=x-4
solve by substitution
3x-x+4=6
2x=2
x=1
Now that you know x, but in in the equation to find y (either equation will work)
y= 1-4
y= -3
now that you have both answers, let's check them.
3(-1) - (-3) =6
yes, it works....
Hopefully this makes sense!
Yes it is correct, I've done the maths myself as wlel
