Well by dividing you will get your answer.
What is 2 ÷ 1?
Your sister would be 1 year old.
Answer:
Step-by-step explanation:
-15.4b + 13 = 9b-41.9
-15.4b-9b = -41.9 - 13
-24.4b= -54.9
divide both side by -24.4
-24.4b/-24.4 = -54.9/-24.4
minus divide by (-)
b= 2.25
Answer:
y = (4/3)x - (22/3)
Step-by-step explanation:
If it's parellel than they have the same slope.
m = 4/3
y = mx + b
y = (4/3)x + b
2 = (4/3)(7) + b
(6/3) = (28/3) + b
-(28/3) -(28/3)
(-22/3) = b
In a year, there's a total of 12 months. So if 4 of them have 30 days, then the rest don't: 12 - 4 = 8 months. So 8 months out of 12 don't have 30 days, and 4 out of 12 have 30 days.
So the ratio of the months with 30 days to the months with other than 30 days is 4/8. To simplify your answer, you divide both sides by 2 and you get a ratio of 1/2.
All in all, the ratio is 1/2.
Hope this helps! :)
