Adult= A
Children= C
First equation:
A+C= 11
A= 11-C
Second equation:
228 total price includes 22dollar x adult and 15dollar x children ticket price. Write the equation:
228= 22A+15C (substitute above value for adult)
228= 22(11-C) + 15C
228= 242-22C+15C
228 - 242 = 7C
14 = 7C
C= 2 (there are 2 children in the group)
Find adult number, using 11= A+C equation,
11= A+2
A= 9
Check: (9x22) + (2x15) = 228
198 + 30 = 228
Answer:
y + 6 = (1/3)(x + 2)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
... y - k = m(x - h)
Fill in the numbers you are given for slope and point.
... y -(-6) = (1/3)(x -(-2))
Simplify the double negatives:
... y + 6 = (1/3)(x + 2)
The top right one is best fit
Answer:
y = -.05x + 6
Step-by-step explanation:
Plug in your x and y coordinates
1 = -.05(10) + b
1 = -5 + b
6 = b
Answer:
25.13 ft
Step-by-step explanation:
To find the circumference of a circle we use the formula
2πr
We plug in the radius of the circle 4 and solve to get 25.13
