Answer: 15
Step-by-step explanation:
Step 1: Subtract 3 from both sides.
Step 2: Multiply both sides by 5/2.
The surface area of each face of a sugar cube is 1*1 = 1 units²
The rectangular box has 6 faces in contact with sugar cubes.
The area of each of two faces is 18*6 = 108 units²
Therefore these two faces touch 2*108 = 216 cubes
There are two other faces each of area 18*8 = 144 units²
Therefore these two faces touch 288 cubes.
There are another two faces, each of area 6*8 = 48 units².
Therefore these faces touch 96 cubes.
The total number of cubes touching the faces of the box are
216 + 288 + 96 = 600
Answer: 600 cubes
Answer:
To find the value of y, you would put your expressions (12y+3, and 51 equal to each other, because they are both the same length)
12y+3=51
12y=48 (51-3=48)
y=4 (divide both sides by 12, 48/12=4)
Then to find x you want to find the missing degree of the triangle
we already know that one degree is 63 and the other is 56,
A triangle equals 180 degrees
56+63=119
Then you want to subtract 119 from 180 to find out the missing degree
180-119=61
x=61 degrees
y=4 and x=61

To compare the fractions, you need to make sure they have a common denominator. So 3/4 = 6/8 and 7/8 = 7/8.
So, to compare the fractions, you now must set an inequality between them:
6/8 < 7/8 or 3/4 < 7/8
Hope this helps! :)
