Answer:
$532
Step-by-step explanation:
Hey There!
So to solve this problem the first thing that we want to do is find the cost of 1 ball
To do so we divide the total cost of 10 balls by 10
280/10=28 so each ball cost 28
now to find the cost of 19 balls we multiply the cost of 1 ball by 19
18x28=532
thus meaning 19 balls cost $532
Do you need it solved or graphed?
Supplementary angles
x+20+5x+10=180
6x+30=180
6x=150
x=25
