How to solve these, you divide the number multiplied by x by both sides.

1. Divide 2/3 by both sides, and you get y = 30.

2. Divide 0.2 by both sides, and you get x = -80

3. Divide 0.8 by both sides, and you get n = 2.5

4. Divide 3/4 by both sides, and you get m = 16

5. Divide -0.4 by both sides, and you get k = -70

6. Divide 3/5 by both sides, and you get h = -10

7. Divide -0.5 by both sides, and you get y = 40

8. Divide 3/5 by both sides, and you get x = 20

I hope this helped! For the fractions, just divide the fraction and divide by both sides with the decimal, and you will get the answer!

Bobby Joe and Billy ray went fishing at the local watering hole and caught a total of 51 fish. Billy Rat caught 17 fewer fish th
blondinia [14]

Answer:

Bobby Joe caught 34 fishes

Billy Ray caught 17 fishes

Step-by-step explanation:

Let the number of fish Bobby Joe caught = y

Let the number of Billy Ray caught = x

Total number of fish caught = 51 fishes

x + y = 51......... Equation 1

Billy Ray caught 17 fewer fish than Bobby Joe.

y = x - 17

Write an expression you can use to find out how many fish, f, each boy caught.

Substitute x - 17 for y in Equation 1

x + y = 51......... Equation 1

x + (x - 17) = 51

x + x - 17 = 51

2x = 51 - 17

2x = 34

x = 34/2

x = 17

Hence, Bobby Joe caught 17 fishes

x + y = 51

17 + y = 51

y = 51 - 17

y = 34

Hence, Billy ray caught 34 fishes

Find the value of L. Perimeter =22. Width is 5. So what is L. On a square
SSSSS [86.1K]
P= L+W 
P= Perimeter, L= Length  and W=Width
Length + Width = Perimeter
So, then P(22) - W(5) = L(17)
Hope that helps.
