Answer:
360 people
Step-by-step explanation:
x = 0.8x + 72 Subtract 0.8x on both sides
0.2x = 72 Divide 0.2 on both sides
x = 360
The answer is (0,-4) (16,0)
the question says that the total price equalled of the antiques is 70. It also says that she bought a table, which was 44, and 2 chairs (x). We can form this equation.
44 + 2x = 70. <------the 2x comes from 2 times the cost of one chair (x) and the . 44 comes from the cost of the table. The total is 70 dollars.
2x = 26 <-------solve algebraicelyy(sry about by spelling)
x = 13 <-------this is the cost of only one chair.
Answer: $13
This ratio means that there are two men for every three women. So, the ratio of women to men is 3:2.
The total amount of students includes both men and women, so you would use 5. The ratio of women to total student is 3:5.
To find the percent, you divide the first number by the second number and multiply by 100. Our first number is the men, which is 2, and the total students are the second number, or 5.
2/5 = .4 * 100 = 40%
A ratio is the same thing as a fraction, so you take the amount of women (3) and put that over the total student body (5). 3/5 is your fraction.
Good luck, and I hope I helped!
Answer:
the center is (-4,7) and the radius is 3
Step-by-step explanation:
The center of a circle can be found using the equation 
and is (h,k) from it. Notice h and k are the opposite value as in the equation.
First write the equation in this form.
Complete the square with each variable to find what numbers should go in place of the question marks.
Add 16 and 49 to both sides of the equation.
So the center is (-4,7) and the radius is 3.
