Answer:
22 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 3600° , then
180° (n - 2) = 3600° ( divide both sides by 180° )
n - 2 = 20 ( add 2 to both sides )
n = 22
Here is how to work it out:
1 + 5 = 6
36 / (1+5) meaning 36 / 6 = 6
6 * 1 = 6 the smaller number
6 * 5 = 30 the larger number
6 the smaller number + 30 the larger number = 36
The smaller number is 6
Answer:
x=4
Step-by-step explanation:
First of all, the sides of the smaller triangle are multiplied by 5 to make it bigger. So, multiply 4 by 5 which gives you 20. So, 20= 3x+8.
Now that we have our equation, we need to isolate the variable.
Subtract 8 from both sides.
20= 3x+8
- 8 -8
Divide both sides by 3.
<u>12</u>= <u>3x</u>
3 3
x= 4
Answer:
2 or less packs
Step-by-step explanation:
15.99 + 1.99g < 20.00 where g is the number of packs of gum
Subtract 15.99 from each side
15.99 + 1.99g - 15.99 < 20.00-15.99
1.99g < 4.01
Divide by 1.99
1.99g/1.99 < 4.01/1.99
g < 2.015075377
Harold must buy whole packs so g =2 or less
