Answer:

Step-by-step explanation:
(180-144)° + 3x + 90° = 180°
36 + 3x + 90° = 180°
x = 18°
Answer:
200 adults
Step-by-step explanation:
We can set-up a system of equations to find the number of adults. We know children and adults attended. We will let c be the number of children and a be the number of adults. Since 200 people attended, then c+a=200.
We also know they made $800 and adult tickets cost $4 and child tickets cost $2. We can write 2c+4a=800.
We will solve by substituting one equation into the other. We start by solving the first equation for c. c+a=200 becomes c=200-a.
Now we substitute c=200-a into 2c+4a=800. Simplify and isolate the variable a.
- 2(200-a)+4a=800
- 400-2a+4a=800
- 400+2a=800
- 400-400+2a=800-400
- 2a=400
- a=200
This means that 200 adults attended and 0 children attended.
Answer:
2.16
Step-by-step explanation:
if x is seconds on the graph and y is the distance then you just look for what is y in the coordinate (6, _ ), in which the line on the graph shows it is 13
hope this helps!!
edit:
it seems i was incorrect, ahh im sorry
so you do have to divide the answer in the end, so 13/6 which is equaled to 2.16
Answer:
h(n) = h(n - 1) + 12
Step-by-step explanation:
Generate the first few terms using the explicit formula
h(1) = - 10 + 12 = 2
h(2) = - 10 + 24 = 14
h(3) = - 10 + 36 = 26
h(4) = - 10 + 48 = 38
This is an arithmetic sequence. To find a term in the sequence add 12 to the previous term, thus
h(n) = h(n - 1) + 12 with h(1) = 2
