ANSWER:
2.5x + 100=600
x=200
step by step explanation:
Total inner angles add up to 720 because its a hexagon. so,
160 + 108 + 113 + 132+ 75+ x = 720
answer should be : 132°
Okay, so we already know that 350 people purchased tickets in hour 1:
17.50(350 + ?) = ?
The question states that in the 2nd hour, there was 20% more people. So basically, we solve for 120% of the people from the 1st hour:
17.50(350 + 1.2(350)) = ?
Multiply 1.2 by 350:
17.50(350 + 420) = ?
Add:
17.50(770) = ?
Multiply:
17.50(770) = 13475
$13,475 was the total amount of money.
Answer:
Teo is 11 years old and Richard is 26 years old.
Step-by-step explanation:
Let R be the age of Richard and T be the age of Teo.
<u><em>First set up the equations:</em></u>
The combined age of Teo and Richard is 37:
R+T=37
Richard is four years old than twice Teo's age:
R=2T+4
<u><em>Then, solve the equations:</em></u>
Substitute (2) to (1) and solve for T:
(2T+4)+T=37
3T=11
T=11
Solve for R using (2):
R=2(11)+4
R=22+4
R=26
