Answer:
x = 45
Step-by-step explanation:
x and 3x are adjacent angles and the form a straight line. Their sum will be 180 degrees
x +3x = 180
Combine like terms
4x = 180
Divide each side by 4
4x/4 = 180/4
x =45
Lets x = <span>number of buttons
</span><span>
Equation:
0.50x + 23.60 = 257
0.50x = 233.4
x = 466.8
Maximum number of buttons = 466
Answer:

Answer: Last option is true,
Step-by-step explanation: All other option are false
The admission fee at a fair is $2.00 for children and $4.00
for adults.
On Saturday 2,500 people entered the fair and $7,000.00 were
collected.
How many children and how many adults attended? Give your
answer, using x for children, y for adults.
Form of: x =, and y =
Let K = no. of children
Let A = no. of adults
2500 people mean
Kids + Adults
K + A = 2500
K = 2500 – A
2K + 4A = 7000
K + 2A = 3500
(2500 – A) + 2A = 3500
A = 3500 – 2500
(A = 1000, adults)
K = 2500 – A
K = 2500 -1000
(K = 1500, Kids)
CHECK:
1500*2 = $3000
1000*4 = $4000
<span>(Total = $7000, people.). </span>
