There would be 138 students in 6 classes because first you'd divide 207 from 9 and get 23 then you'd multiply 23 to 6 and get 138.
A unit rate is when you find a rate when one variable (or value) is equal to one.
Let's find the unit rate for the price of the bananas.
1.98/6= 0.33
It is 33 cents for one banana. That is the unit rate.
I hope this helps!

Its B , 6 because if you subtract 98 from 530 you get 432 and if you divide that by 72 you get 6 :)
Answer:

Step-by-step explanation:
a + 25%·a = a(1 + 0.25) = 1.25a

<em>Comment on percentages</em>
The symbol "%" is a shorthand way to write "/100", so 25% = 25/100 = 0.25.
Of course, 100/100 = 100% = 1.
Adding 25% of something to 100% of it gives 125% of it, the original amount multiplied by 125/100 = 1.25.
Answer: 19 cm
<u>Step-by-step explanation:</u>
99 = 
99 = 
198 = (2x + 13)(x - 4)
198 = 2x² + 5x - 52
0 = 2x² + 5x - 250
0 = 2x²- 20x + 25x - 250
0 = 2x(x - 10) + 25( x - 10)
0 = (2x + 25)(x - 10)
0 = 2x + 25 or 0 = x - 10
= x or x = 10
Since length cannot be negative, can be disregarded
Larger base: x + 9 = 10 + 9 = 19
