Given table is given below
The relationship between the number of crocodiles and the number of alligators is not proportional across all lakes. Only two of the lakes have crocodiles and alligators in the same proportion. Which two lakes are they?
lake A and lake B
lake B and lake C
lake A and lake E
lake C and lake D
Answer : lake A and lake E
Lake
---> Crocodiles
---> Alligators
---> Ratio
A
---> 4
----> 5
B
---> 21
---> 35
C
---> 3
---> 9
D
---> 6
---> 16
E
---> 24
---> 30
The ratio of A is 4: 5
B is 21: 35 = 3 : 5
C is 3 : 9 = 1 : 3
D is 6 : 16 = 3 : 8
E is 24: 30 = 4 : 5
Lake A and E has the same ratio 4: 5
Answer:
8 = x
or
x = 8
Step-by-step explanation:
x – 3 = 5
x + -3 + 3 = 5 + 3
x = 5 + 3
(5 + 3 = 8)
x = 8
I'll try to do each individual step, hopefully that'll clear it up
w= 3(2a+b)-4
w+4= 3(2a+b)
(w+4)/3 = 2a+ b
2a= ((w+4)/3) - b
a= (((w+4)/3) - b)/ 2
<span>So before we can participate in our Chem labs, we need to answer questions regarding the experiment. I'm not the best at Chemistry and I'm having some trouble with this one problem.
Here's the experiment's instructions (Part A)
And the problem, "When performing today’s experiment, your lab partner decides to add all the reagents into one beaker instead of two separate beakers. After adding everything together and waiting a significant amount of time, you see no reaction occur. What was the problem?"
Could it be that all of the separate beakers form different mixtures and just adding everything together at once doesn't allow that to happen? I have honestly have no clue, any help is appreciated</span>
Can u put a picture closeup
