Answer: 3</h3>
========================================
Work Shown:
Solve the equation for y
-13y - 5 = 8
-13y = 8+5
-13y = 13
y = 13/(-13)
y = -1
Then use this y value to compute 4y+7
4y+7 = 4(-1)+7 = -4+7 = 3
Answer:
It's 15°
Step-by-step explanation:
BC+60°+85°+200° =360°
BC+345°=360°
BC=360°-345°
Bc=15°
Answer:
74 adult tickets and 106 children tickets
Step-by-step explanation:
let x be the number of adults tickets sold out
and y the number of chlidrens tickets that sold out for the 7:15 pm show
The equations that determine our problem are
x+y=180
12.50x+8.50y=1826
lets separate x from first equation x=180-y and replace at the second equation
12.50(180-y)+8.50y=1826
12.50*180-12.50y+8.50y=1826
2250-4y=1826
4y=2250-1826
y=424/4=106
so x=180-y=180-106=74
The independent variable is hours and the score or points is the dependent variable .equation is s=3h
