7-12 is like a negative number so it will be -5. And 13-18 would be -5 also.

What you need to do is take 7-12 and 13-18 and flip them and add a negative sign to your answer .
So 7-12= -5 and 13-18= -5

Triple my number add six and subtract my number twice I get my number plus three

liberstina [14]

Let the number be x.

Triple the number means 3x
add 6 means 3x + 6
subtract the number twice 3x + 6 - x - x
the result is the number plus 3 means that the result is x + 3

So, combining these into an equation, we get:
3x + 6 - x - x = x + 3

If we solve this equation for x, we will get:
x + 6 = x + 3
The x will cancel out and we will get : 6 = 3

Therefore, this is a false statement.

The circle has center O. Its radius is 9 ft, and the central angle a measures 50°. What is the area of the shaded region?

Ivahew [28]

Answer:

35.34305555555

Step-by-step explanation:

You must calculate the percentage taken out of the circle by the shaded region. This would be about 13.8%. Then you take the overall area of the circle and multiply it by the percentage. This should give you your answer.

REMEMBER TO ROUND IF YOU ARE SUPPOSED TO, THERE IS NO INDICATION ON BRAINLY. WITHOUT ROUNDING YOU CAN GET THE ANSWER WRONG.
