9 students in the class play in the school band.
30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3
In math, the word of means multiplication, so: 0.3 x 30
Which equal 9.
You can also turn the percentage into a fraction, it's really up to preference.
30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9
Move the -7 to the right, its sign will flip (do you know why?)
Negate both sides to change -x to x
-x = 16+7
-x = 23
x = -23

Answer:

Step-by-step explanation:
we know that
If the triangle of the figure is a regular polygon
then
Is an equilateral triangle
Remember that
The equilateral triangle has three equal sides and three equal interior angles
The measure of each interior angle is 60 degrees
To find the area of the equilateral triangle apply the law of sines

we have that

substitute

Wouldn't it be -54. Because when you subtract 5-59 you get a negative number... IT WOULD BE FREEZING THERE!!! I HOPE THIS HELPED
