So if the ratio of red to blue is 8:3 and there are 15 blue cars then there are 40 red cars.
If the ratio of red to white is 2:10 then then there are 200 white cars.
Explanation:
15 divided by 3 is 5. So you multiply 8 by 5 to get 40. 40:15 reduces to 8:3.
With 40 red cars the ratio of 2:10 would be made into 40:200.
The fractions/ratios have to remain proportional.
Answer: yes
Step-by-step explanation:
You’re multiplying every x value by 4 to get the y values
(Someone got mad at me for not including a better explanation so here you go:
x = 3 y = 12..... 3(k) = 12 (divide both sides by three)
k = 4
x = 5 y = 29..... 5(k) = 20 (divide both sides by five)
k = 4
So on and so forth for the rest of the table
Answer: its 31.4 i think cuz if you divide 157 and 5 you get 31.4 in an hour

Answer:
38
Step-by-step explanation:
2 + 3^2 (5 - 1)
