Answer: 60= $3.00 and 30= $4.00
x=# of $3 tickets
90-x=# of $4 tickets
$3x+$4(90-x)=$300
3x+360-4x=300
-x+360=300
-x=-360+300
-x=-60
x=60 $3 tickets
90-60=30 $4 tickets
Answer:
Step-by-step explanation:
The best way to go about this is to use a trig identity. You have the unknown opposite the angle and the hypotenuse, so its best to use the sine identity: 
, where O is the opposite side, and H is the hypotenuse.
Set up the equation as:
, and solve for X.
I got x=7.718, rounded to x=8.
If I helped, a brainliest answer would be greatly appreciated!
Answer:
Step-by-step explanation:
x/1=3/(1/8)
x=3(8/1)=24 bottles per minute
Hello!
To solve this equation, we need to isolate the variable on one side of the equation to see what it equals.
As you can see, 2.7 is added. To get it onto the other side and cancel it from the one side, you will subtract it from both sides as shown below. Note that because of the commutative property, we can switch the places of 2.7 and x.
x+2.7-2.7=17-2.7 (Note that 2.7=2.7 is 0 in this equation.
x=14.3
Our solution is x=14.3
I hope this helped you learn how to solve equations a bit better!
10+8h=66
minus 10 both sides
8h=56
divide both sides by 8
h=7
