Answer:
Step-by-step explanation:
Let the number of blue marbles be x
The number of green marbles = 3x - 2
Total marbles= 18
x + 3x -2 = 18
4x - 2 = 18
4x = 18+2
4x = 20
x =20/4
x =5
The number of blue marbles = 5
The number of green marbles = 3*5 - 2 = 15 -2 = 13

Answer:
A) 684 in^2
Step-by-step explanation:
Since it needs to be painted all around the box we have to find the surface area of the box
The surface area of cuboid is
=2lw+2lh+2hw (l: length, w: width, h: height)
=2×15×12+2×6×15+2×6×12
= 684 in^2
Answer:
2 2/3 - 1 3/4 = 11/12
Step-by-step explanation:
You could convert them both to improper fractions then you would make them have common denominators so the least common denominator for the would be 12 so you would multiply them and then you would subtract them to get your answer of 11/12.
2 2/3 = 8/3 times 4 = 32/12
1 3/4 = 7/4 times 3 = 21/12
32/12 - 21/12 = 11/12
