We estimate that 12/480=1/40 fish are tagged, so 600 is 1/40 of the total number of fish. This means that there are about 600*40=24000 fish total in the pond.

The following equations are solved in terms of x:
a) 2x - 3 = y
2x = y + 3
x = (1/2)y + 3/2
b) 2 + 2x - 1 = 4y
2x - 1 = 4y
2x = 4y + 1
x = 2y + 1/2
c) 2A + 4x + 3B = 10
4x = 10 - 2A - 3B
x = 5/2 - (1/2)A - (3/4)B

39.71 = p
∴ p = 39.71

QUESTION POSTED AT 14/12/2019 - 06:30 PM
2x - 13 = 3x + 18
Ok, so we have to get the variable (x) on one side and the number on the other side.
So first lets add 13 to both sides.
2x - 13 = 3x + 18
+13 +13
-------------------------
2x = 3x + 31
Next lets subtract 3x from both sides.
2x = 3x + 31
-3x = -3x + 31
-----------------------
-x = 31
Lastly, we need to switch the negative and positive signs.
-x = 31
x = -31
So the answer is x = -31

Answer=25%
14 red marbles
12 yellow marbles
26 total marbles
To solve this, we need to first find out the probability of the individual events...
The odds of selecting a red marble is 14 out of 26 total marbles: 14/26
The odds of selecting a yellow marble after the first marble was NOT replaced is 12 out of 25. (25 since the first marble wasn't replaced: 26-1=25) 12/25
Now lets multiple both probabilities together to solve for the chance of both happening consecutively....
14/26*12/25= 168/650=84/325
84/325=0.25846153846= 25%

First, you would substitute z with 12 since z = 12.
12 ÷ 3 - 5 (12) + 4 (12 - 2).
Then, you would follow the order of operations.
12 ÷ 3 - 60 + 40
4 - 60 + 40
-56 + 40
-16

Let
x = time of Byran's work
x + 10 = time of Andy's work
Rate is usually expressed a reciprocal. The total rate will be 12 minutes.
1/x + 1/(x + 10) = 1/12
The value of x will be 20 minutes.
Therefore Byran can take 20 minutes while Andy can take 30 minutes.
