I think when you have a fraction like that, you multiply the denominator on both sides obviously by the first step
1 - 3x/5 = -7
Multiply on both sides
1 - 3x/5 * 5 = -7 * 5
and Solve
1 - 3x = -35
Subtract 1 from both sides of the equation
-3x = -36
Divide both sides by -3
-3x / -3 = -36 / -3 (← answer)
x = 12
Hope it helps
12 has more factors the 19,21,,23, and 25.
The apothem represents one side of the right triangle to be solved. Specifically, it represents the height of the triangle.
The radius of the polygon represents the hypotenuse of the right triangle that is going to be solved.
Therefore, we can infer that the radius of the polygon is greater than the apothem because the hypotenuse is greater than all sides of a triangle.
Answer:
the radius of the polygon is greater
She is not correct, because $3.00 divided by 6 is 50 cents, so by using that equation she could evaluate that she is wrong and find the correct answer.
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
