There is only 20 different ways you can do for 1 topping and 1 cheese for this question. Because every topping(10) on every cheese(2) gives you 20 different choices you can have a pizza.
She has been going for 6 minutes. Since she’s flown 50 miles, her rate is 50/6. If you simplify it is 12 miles per hour.
Answer:

Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle = 
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* = 
90* = 10
Answer:
x = 24
Step-by-step explanation:
=
+ 4 Multiply though by 12 to clear the fraction
4(6 + x) = 3x + 48 Distribute the 4)
24 + 4x = 3x + 48 Subtract 3x from both sides of the equation
24 + x = 48 Subtract 24 from both sides.
x = 24
