Answer:
90%
Step-by-step explanation:
Since 90/100 seats are taken then we can say;
90/100=9/10=.90*100=90%
It's an easy problems. what equations are you trying to find?
Answer:
- Define your variable and write your equation: 36 + b + (3b-28) = 180°.
- measure of the second angle: 43°.
- measure of the third angle: 101°
Step-by-step explanation:
a = 36
c = 3b - 28
a + b + c = 180°
a = measure of the first angle
b = measure of the second angle
c = measure of the third angle
then:
1) 36 + b + (3b-28) = 180 ⇒ )Define your variable. Write your equation and solve)
b + 3b + 36 - 28 = 180
4b + 8 = 180
4b = 180 - 8
4b = 172
b = 172/4
2) b = 43° ⇒ measure of the second angle
c = 3b - 28
c = 3*43 - 28
c = 129 - 28
3) c = 101° ⇒ measure of the third angle
Check:
36° + 43° + 101° = 180°
Here is the method for solving that equation:
Step #1: Write the equation:
-15x = 0
Step #2: Divide each side of the equation by -15 :
<u>x = 0</u>
