I don't know which quadratic equations you have learned. you can choose the quadratic formula: x= -b +- square root of D divided by 2 times a. There is also factoring or solving by undoing.

2/6 is also equal to 1/3. so if you multiply 69 by (1/3) it equals 23. giving you 23 kit kats.

x= 4. 225 is 15 times bigger than 15. so if you divide 60 by 15 it gives you your answer of 4.

Anna walked 8 miles in 3 hours. Juan walked 14 miles in 5 hours. Are these rates in proportion?
Veronika [31]

These rates are not in proportion. Juan walked faster.

Explanation:

First, we want to make these ratios to have the same denominator so we can compare the numerators. To do this, do 3x5 and 8x5 to get 40:15. Then, we do 5x3 and 14x3 to get 42:15. Now we can just compare the numbers 40 and 42, and since 42 < 40, we know Juan walked faster.

If there are 40 boys and 20 girls in a room, fill out all possible ratios of boys to girls that could be made.
marysya [2.9K]

Answer:


Step-by-step explanation:

A ratio compares two quantities in terms of multiplication. For example, suppose that there are 10 boys and 15 girls in a classroom. One way, not using ratios, to compare these quantities would be to say that there are 5 more girls than boys in the classroom. To employ a ratio, we say that the ratio of boys to girls is 10 to 15, or 2 to 3. In other words, for every 2 boys in the classroom, there are 3 girls.


In your case, for every 40 boys, there are 20 girls. if we simplify this all the way down, we can get 2 to 1.

All of the following are ratios that apply to your question:

40 to 20

20 to 10

10 to 5

4 to 2

2 to 1
