10x-12 is the answer I believe
Divide 21 / 3/4 or multiply by its reciprocal 4/3.
21 * 4/3 = 84/3 = 28
Therefore there will be 28 slices.
<u>The question is not complete. I have assumed you want to calculate the length of each piece.</u>
Answer:
<em>The shortest piece is 4 inches long</em>
<em>The longest piece is 8 inches long</em>
Step-by-step explanation:
Equations
One piece of tubing is two times the other.
Let's call
x=the shortest piece of tubing
2x=the longest piece of tubing
The total length of the piece of tubing is 12 inches, thus:
x + 2x = 12
Simplifying:
3x = 12
Dividing by 3:
x = 12 / 3 = 4
x=4, and 2x=8, thus:
The shortest piece is 4 inches long
The longest piece is 8 inches long
Answer:
Perimeter = 50 inches
Step-by-step explanation:
Use pythagoreon theorem to find the hypotenuse
a^2 + b^2 = c^2
3^2 + 4^2 = 5^2
9 + 16 + 25 = perimeter
perimeter = 50
terms of a geometric sequence is given by:
