Answer:
n = 84
Step-by-step explanation:
18 + 3 = 21, so that means the quotient of the number and 4 is 21.
21 * 4 = 84
CHECK:
84 / 4 = 21
21 - 3 = 18
Answer:
h = 110°
Step-by-step explanation:
1) A pentagon has 5 sides that sum up to 540°. We know it is 540° because of this formula that is used to find the sum of the interior angles of any polygons. <u>n</u> is the number of sides.
= (n - 2) x 180
= (5 - 2) x 180
= 3 x 180
= 540°
2) We can now set up an equation.
70 + 100 + 120 + 140 + h = 540
430 + h = 540
h = 540 - 430
h = 110°
17.48 lbs on Mars
108.65 lbs on Jupiter
So subtract
108.65
- 17.48

x = 0
here's an explanation
3x = 9x
subract 9x from both sides
3x - 9x = 6x 9x - 9x = 0
this gives you
6x = 0
divide 6x on both sides
6x/6 = x 0/6 = 0
x = 0
