-5x+4y-7x-9y
-12x-5y
12x+5y=I
An equation of circle has form

So, the center is (13;1)
Now we need to find a radius
Let's create an equation

So radius is 2
Answer:
Janine is 28. Ingrid is 30.
Step-by-step explanation:
Let the ages be x and x + 2 for Janine and her sister, respectively.
x/7 + (x + 2)/3 = 14
Multiply both sides by the LCD, 21, to get rid of denominators.
21 * x/7 + 21 * (x + 2)/2 = 21 * 14
3x + 7(x + 2) = 294
3x + 7x + 14 = 294
10x = 280
x = 28
x + 2 = 30
Answer: Janine is 28. Ingrid is 30.
Answer:
I'm not so sure what you mean from your question but if we discussed the Average of 11 and 35( positive integers), we would say that it's 23<u>.</u>
KILO=1000.............. MILLI= thousandth
1kg is 1000 grams
1 milligram is one thousandth of a gram, so a 1 gram = 1000mg.
in 36 kg, then there are 36 * 1000 grams.
and in (36*1000) grams there are (36*1000)*1000 mg, 36,000,000 mg.
