X-2y=10 x+3y=5 please hellppppppp

X-2y=10 X+3y=5 Please Hellppppppp

Answers

Answer 1

Answer:

x=8,y=-1

Step-by-step explanation:

x-2y=10

x=10+2y

10+2y+3y=5

5y=-5

y=-1

x-2(-1)=10

x=8

Answer 2

The solution to the system of equations x - 2y = 10 and x + 3y = 5 is x = 8 and y =-1

How to solve the equation?

The system of equations is given as:

x - 2y = 10

x + 3y = 5

Subtract both equations

-2y - 3y = 10 - 5

Evaluate

-5y = 5

Divide both sides by -5

y = -1

Substitute y = -1 in x - 2y = 10

x - 2(-1) = 10

This gives

x + 2 = 10

Subtract 2 from both sides

x = 8

Hence, the solution to the equations is x = 8 and y =-1

Just carpet has eight different quality grades of carpeting. Three types are being selected for a corporate test on durability. how many different samples of size 3 can be taken without replacement? how many different samples of size 5 can be taken without replacement?

Answers

Answer:

When we have a set of N elements, the number of combinations of K elements (such that N ≤ K) from these N elements is:

[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]

Then if we have 8 different types of carpet, and we want to see how many different samples of 3 types we can choose, we just need to replace N by 8, and K by 3 in the above equation:

[tex]C(8, 3) = \frac{8!}{(8 - 3)!*3!} = \frac{8!}{5!*3!} = \frac{8*7*6}{3*2} = 56[/tex]

So there are 56 different samples.

Now we can do the same, but this time we want to use 5 types of carpet, then we will have K = 5.

[tex]C(8, 5) = \frac{8!}{(8 - 5)!*5!} = \frac{8!}{3!*5!} = 56[/tex]

Again, we have 56 different samples.

The sum of 6 times a number and 8 times another number is 12. The difference of those numbers is 9. What are the two numbers

Answers

Answer:

(x,y): (6 , -3) or (-30/7 , 33/7)

Step-by-step explanation:

6x + 8y = 12

x = y + 9 or   y = x+ 9

if x = y+9

6*(y+9) + 8y = 12

14y = -42

y = -3 and x = 6

if y = x+9

6x + 8*(x+9) = 12

14x = -60

x = -30/7   and y = 33/7

The measure of one angle is thirteen less than five times the measure of another angle. The sum of the measures of the two angles is 140°. Determine the measure of each angle in degrees.

Answers

Answer:

The two angles are 25.5 and 114.5

Step-by-step explanation:

x = measure of one angle

5x - 13 = measure of the other angle {one angle is 13 less than 5 times the other}

x + 5x - 13 = 140 {sum of the two angles is 140}

6x - 13 = 140 {combined like terms}

6x = 153 {added 13 to each side}

x = 25.5 {divided each side by 6}

5x - 13 = 114.5 {substituted 25.5, in for x, into 5x - 13}
