Answer:
If you've more doubts you can ask :)
Step-by-step explanation:
If the centre of a circle is (a, b) and radius r, then the equation of the circle is :

<em><u>First we will find the centre, (a , b): </u></em>
<em><u /></em>
<em><u /></em>
<em><u>Find radius:</u></em>

Diameter is the distance between (-1, 4) and (3, -2)


Therefore , 
<em><u>Equation of the circle is : </u></em>
<em><u></u></em>
Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.

Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.

Indeed, those two numbers are relatively prime.
Answer:
16 packages of muffins
Step-by-step explanation:
1) First you need to find out how many muffins you need total. If each person has two muffins and there are 48 people, how muffins would that be? To find out, multiply 48 and 2 together.
48 * 2 = 96
So now we know that we must have 96 muffins in total
2) Now we have to find out how many muffin packages we will need. If there are 6 muffins in each package and we need to have 96 muffins in total, how many packages will we need? To find out, divide 96 by 6.
96/6 = 16
From this we know that you will need 16 packages
<span>The correct answer is D. The number 7 is subtracted from the first term, 2x/3, but then an equal sum is added, and the two effectively cancel each other out. This means that the value of the first expression is essentially 2x/3, which is option D.</span>
If you would like to find the percent markup, you can calculate this using the following steps:
x% of $20 is $29
x% * 20 = 29
x/100 * 20 = 29
x = 29 * 100 / 20
x = 145%
145% - 100% = 45%
The correct result would be 45%.
