What is y-13x=9 and how did you solve it

Mathematics
1 answer:
AURORKA [14]3 years ago
4 0

Simplifying

y + -13x = 9

Reorder the terms:

-13x + y = 9

Solving

-13x + y = 9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

-13x + y + -1y = 9 + -1y

Combine like terms: y + -1y = 0

-13x + 0 = 9 + -1y

-13x = 9 + -1y

Divide each side by '-13'.

x = -0.6923076923 + 0.07692307692y

Simplifying

x = -0.6923076923 + 0.07692307692y

Rudy has 10 white she sells 23 pink seashells and 21 Brown see cells if he divides the cells into equally between three friends
Alex_Xolod [135]

Answer:

Each friend will get 18 sea shells.

Step-by-step explanation:

Given:

Rudy has white sea shells = 10

Rudy has pink sea shells = 23

Rudy has brown sea shells = 21

Number of friends = 3

Rudy divides the sea shells into equally between three friends.

We need to find how many sea shells each friend can get.

Now first we find the total number sea shells.

Total number of sea shells = white sea shells + pink sea shells + brown sea shells = 10 + 23 + 21 = 54

Now to find number of sea shell each friend can get we will divide total number of sea shell with number of friends.

number of sea shell each friend can get = \frac{\textrm{Total number of sea shells}}{\textrm{ Number of friends}} = \frac{54}{3}=18

Hence each friend will get 18 sea shells.

The combined height of one fir tree and one pine tree is 212121 meters. The height of 444 fir trees stacked on top of each other
Drupady [299]

Answer:

Height of fir tree = 9 meters

height of pine tree= 12 meters

Step-by-step explanation:

The combined height of one fir tree and one pine tree is 21 meters. The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.

Let x be the height of fir tree and y be the height of pine tree

x+y=21

Subtract x from both sides

y=21-x

height of 4 fir trees = pine tree +24

4x=y+24

Substitute 21-x or y in the above equation

4x=21-x+24

Add x on both sides

5x=45

Divide by 5 on both sides

x=9

Now plug in 9 for x and find out y

y=21-x

y=21-9

y=12

Height of fir tree = 9 meters

height of pine tree= 12 meters
