Answer:
Grace is right
Step-by-step explanation:
3(2-x)-2(6x-8)=
so:
3×2 is 6
3×(-x) is -3x
-2×6x is -12x
-2×(-8) is 16 because -×- equals +
3(2-x)-2(6x-8)
=6-3x-12x+16
= -15x+22
Answer:

Step-by-step explanation:
Colored Fabric = 48 mm
White Fabric = 1.2 cm
<u><em>Ratio of white fabric to colored fabric is:</em></u>
48 mm : 1.2 cm
To express any ratio, we need to equalize the units ( 1 cm = 10 mm)
=> 48 mm : 12 mm
÷12 ÷12
=> 4 : 1
