Answer:
12
Step-by-step explanation: Because 12 old dolls - 6 dolls = 6 dolls. Then you add 6 old dolls and 6 new dolls and you get 12 old and new dolls. Sorry if this is confusing. I tried to make it less confusing.
Rewriting in intercept form
4x+6y= 3 becomes
y= 4x/6 + 3 /6 = ⅔x + ½
it's m = 2/3
for the second line
6x + 9y = 7
y= 6x/9 + 7/9 = ⅔x +7/9
it's m = 2/3
so the two lines are parallel..
100% sure ,
don't forget to give brainliest if correct
Answer:
Company C
Step-by-step explanation:
The first thing you want to find is called the unit price. So, in order to do that, you will have to divide the price by units. Let's start with company A. 34.20 divided by 12 = $2.85. So, that is the price for 1 eagle. Next, you divide 42.45 by 15, which equals $2.83. Finally, 45.12 divided by 16 = 2.83. So, what I did was put them in a chart like organization as shown below.
A = 2.85
B = 2.83
C = 2.82
The best price would be the one that is cheapest. So, Company C is the best buy because it is the cheapest per one eagle. Hope this helped!
