Answer:
x = 21
Step-by-step explanation:
5x + 18 = 7x - 24
=> 5x - 7x = - 24 - 18
=> -2x = - 42
=> x = -42 / -2
=> x = 21

Answer:
There are 67,600 possible combinations for this vault.
Step-by-step explanation:
First dial: 100 possible values
Second dial: 26 possible values
Third dial: 26 possible values.
How many possible combinations are there for this vault?
Multiplication of these values. So
100*26*26 = 67600
There are 67,600 possible combinations for this vault.
A coordinate rule is like were the the shape is I think
The formula for the surface area of a right cylinder is 2πrh + 2πr^2. r is the radius, and h is the height.
In this instance, the radius is 4, so plug that in for r. (I.E. Replace r with 4).
The formula is now 2π4h + 2π4^2.
Next, plug in the height, 8 for h.
Now we have 2π4(8) + 2π4^2, which is approximately 301.59.
The surface area is 301.59. (Unit of measure was not specified)
