Answer: S = 50W + 75
Step-by-step explanation:
I got to this answer by a bit of trial and error.
I first noticed that the relationship between the balance in the savings account from week to week was increasing by 50.
But when I tried W = S + 50, that did not work at all because when I plug in 125 for S, I should get 1 for W, but instead I get 175. So I realized I had something backwards.
I then tried listing the relationship as ordered pairs of (W, S).
For example I did (1, 125), (2, 175), (3, 275) and so on. So I thought of S like y and W like x where S is a function of W. I used the equation y = mx +b or S=mW + b as an outline. I figured that W would have to be multiplied by 50 to get that jump between the numbers in the S column. But I could not do S=50W + 125 because if W = 1, S = 175 when S should equal 125. So I subtracted 50 from the 125 and got 75. So my final equation was S=50W+75. If you test it with the ordered pairs listed above, you will see that the equation checks out. Try it yourself! I hope this was helpful in some way. Good luck!
Answer:
The number of mollies fishes in the aquarium is 20 .
Step-by-step explanation:
Given as :
The capacity of aquarium = 40 gallons
∵ 1 gallon = 4 quart
∴ 40 gallons = 4 × 40 = 160 quart
Now, According to question
0.25 inches of fish required 1 quart capacity
I.e for 1 quart capacity , 0.25 inches fish
So. for 160 quart capacity , 0.25 × 160 = 40 inches fishes
Now the size of mollies fish = 2 inches
Then , number of mollies fish = 
I.e Number of mollies fish = 
= 20
Hence The number of mollies fishes in the aquarium is 20 . Answer
Answer:
24
Step-by-step explanation:
4 times 6 =24
72 chicken and 4ó3 dogs come to 535 animals altogether.
The equivalence of the equation is 5x + 48 = 5x + 3.
Since 48 cannot be equal to 3, hence there are no solution.
<h3>What is the value of x?</h3>
Given the equation; x-4[ x - 2( x + 6) ] = 5x + 3
We remove the parentheses
x-4[ x - 2( x + 6) ] = 5x + 3
x-4[ x - 2x - 12 ] = 5x + 3
x - 4x + 8x + 48 = 5x + 3
5x + 48 = 5x + 3
We can go further and collect like terms
5x - 5x + 48 = 3
48 ≠ 3
Since 48 cannot be equal to 3, hence there are no solution.
