The ratio of pencil to rulers is 6:10. the are 21 pencils. how many rulers are there
Reika [66]

There would be 35 rulers.

In order to solve this, use cross multiplication.

6/10 = 21/x -----> cross multiply

10*21 = 6*x

210 = 6x

35 = x

Solve this system of linear equations. Separate the x- and y-values with a comma.
vodomira [7]

Answer:

x = \frac{5}{2}, y = \frac{5}{4}

Step-by-step explanation:

1. Isolate for x in one of the equations:

2x = 9x - 14y

2x-9x = 9x-9x -14y

-7x = -14y

-7x/-7 = -14y/-7

x = 2y

2. Substitute 2y in for x in the second equation:

9(2y) = 40 - 14y

3. Simplify:

18y = 40 - 14y

4. Isolate for y:

18y+14y = 40 -14y+14y

32y = 40

32y/32 = 40/32

y = \frac{5}{4}

5. Substitute the new y-value into the simplified expression x = 2y:

x = 2(5/4)

x = \frac{5}{2}

hope this helps!
