<h3>
Answer: x = 21</h3>
Explanation:
The two angles shown combine to 180 degrees because the angles form a straight line.
(3x+18)+(4x+15) = 180
7x+33 = 180
7x = 180-33
7x = 147
x = 147/7
x = 21
Answer:
=9 * 1000 / 3600
=9000 / 3600
=2.5m/s
note that 1000m makes 1km and 3600seconds make an hour

Answer:
y=mx+bx
Step-by-step explanation:
You could either use (7,19) or (9,29) to find the equation....
Y=mx+b
You plug in you x and y, then we are trying to solve for b
x=7, y=19
19=m(7)+b
7m+b=19
-7m -7m
b= 19 - 7m
Y=7m+1

Answer:
a = 374
Step-by-step explanation:
Given that:
Cost of children ticket = $6
Cost of adult ticket = $9
Total amount spent = $1219
Total number of people = 16
Let :
Children = c
Adult = a
a + c = 16 - - 1
6c + 9a = 1219 - - - 2
From 1
c = 16 - a
Using 2
6(16 - a) + 9a = 1219
96 - 6a + 9a = 1219
3a = 1123
a = 374.33
Adult = 374.33
The number should be a whole number, maybe there is a problem with the parameters given.
