Answer:
c I just saw ur question sorry if I too late
Answer:
Children: $13
Adults: $18
Step-by-step explanation:
Well for both sets we can set up the following system of equations,

So first we need to solve for a in the first equation.
3a + 4c = 106
-4c to both sides
3a = -4c + 106
Divide 3 by both sides
<u>a = -4/3c + 35 1/3</u>
Now we plug in that a for a in 2a + 3c = 75.
2(-4/3c + 35 1/3) + 3c = 75
-8/3c + 70 2/3 + 3c = 75
Combine like terms
1/3c + 70 2/3 = 75
-70 2/3 to both sides
1/3c = 4 1/3
Divide 1/3 to both sides
c = 13
Now we can plug in 13 for c in 3a + 4c = 106,
3a + 4(13) = 106
3a + 52 = 106
-52 to both sides
3a = 54
Divide 3 by both sides.
a = 18

Answer:
P = 47.1 units
Step-by-step explanation:
the perimeter of the pair of straight opposite sides is 11+11, or 22
now you have 2 semi-circles, which equals 1 full circle which, if we find the circumference to then we just add it to 22 to get the entire answer
Circumference of circle with diameter of 8:
C = 2πr
C = 2π(4)
C = 8π
C = 25.13
now add 22 + 25.13 to get 47.1 rounded to nearest tenths place
Y-intercept: (0,-7)
Slope: 2
