Answer:

y=90

Step-by-step explanation:

Collect the like terms first (3y, 8y, and y) and add them together, which gives you 12y. Equation looks like this so far 64-12y/40=37

Divide the -12 by 40, which can be reduced to -3/10.Equation so far: 64-3/10y=37

Multiply each side by 10 to cancel out the 10 in -3/10y. Equation so far: 640-3y=370

Use inverse operations to move the 640 with the 370. Equation so far: 3y=370-640

Subtract 640 from 370, which gives you -270. Then you'll have -3y=-270 and divide both sides by -3.

64 - (3y + 8y + y) / 40 = 37

Simplify 3y + 8y + y

64 - 12y / 40 = 37

Add 12y / 40 to both sides and subtract 37

27 = 12y / 40

Multiply both sides by 40

1080 = 12y

Divide both sides by 12

90 = y

Answer:

x = 10

Step-by-step explanation:

In the last step, you can see that the fraction $\frac{1}{5}$ has been multiplied by its reciprocal $\frac{5}{1}$ , making it cancel out. The reciprocal has been multiplied to both sides, so all you need to do is multiply $\frac{6}{3}$ · $\frac{5}{1}$ :

6 · 5 = 30

3 · 1 = 3

So now you should have the fraction:

x = $\frac{30}{3}$

But, you can still simplify the fraction by dividing 30 by 3:

x = 10

The number of blue fish to red fish in a tank is

Lena [83]

51 blue fish.

If there is 34 to 50 blue to red fish in tank A. Then tank B is 51 to 75. Because 75 is 1.5 times larger than 50 you have to multiply 34 by 1.5 to get 51.
