Please see the picture attached.
Answer:
No
Step-by-step explanation:
I'm not quite sure what a ratio table is, but I can explain it the way I understand it.
The initial ratio is 10:8 which is 1.25 as a decimal.
Now let's add five to each number to represent the kids joining the class, this will result in the following:
15:13 which is 1.153846154 as a decimal.
Therefore, the ratio doesn't stay the same just because you added the same number of people to each group.
Hope this helps :)
Answer: y=(x-1)/2
Step-by-step explanation:
To find the inverse, you want to switch the y with x and x with y. Then, you solve.
y=2x+1 [switch y with x and x with y]
x=2y+1 [subtract both sides by 1]
x-1=2y [divide both sides by 2]
(x-1)/2=y
Now, we know that y=(x-1)/2 is the inverse.
keeping in mind that the ratio of the sides is the same as the ratio of the perimeters, Check the picture below.
the answer is 3.2 kilometers.
yaaaaaaaaayyyyyy!!!!
