Answer:
Step-by-step explanation:
Ratios can be of 2 types here:
Part to Part
and
Part to Whole
Part-to-Part ratios give the relationship between 2 distinct things/groups. Such as the ratio of male to female in a class, or ratio of water to sugar in a drink etc.
Part-to-Whole ratios give the relationship between one group/thing to the whole population. Such as the ratio of male to total students in a class, or the ratio of cups of sugar to total cups of drinks etc.
<u>Note:</u> If there are 2 parts in a population, we can essentially write 3 ratios. For example, the ratio of male to female in a class is 4 to 5. So in total there are 4+5 = 9 parts (whole). So we can say:
ratio of male to total population is 4 to 9
ratio of female to total population is 5 to 9
Also,
ratio of male to female (as stated before) is 4 to 5
3 ratios.

Answer:
he would have to buy the blue masks at 1.50 each
Step-by-step explanation:
you divide

witch equals 2.25 so he can only spend $2.25 per mask so that's how i found out he can only buy the blue masks
Answer: i do not no
Step-by-step explanation:
You are told that y=-5, so just use that value for y in the second equation...
5x+4(-5)=-20
5x-20=-20
5x=0
x=0 so the solution, when the lines intersect, is the point (0,-5)
