Answer:

X=3, y=-6

Step-by-step explanation:

7x+4y=-3 equation 1

-7x-5y=9 equation 2

     -y=6. Add above two equations    

      Y=-6

solve for x by inputting y value into either equation.

7x+4(-6)=-3

7x-24=-3

7x=21

x=3

check answer by inputting x and y values into either equation

-7x-5y=9

-7(3)-5(-6)=9

–21+30=9

9=9

Step-by-step explanation:

In a GP, there is a common ratio between the terms.

8 / (-16/5) = 8 * (-5/16) = -2.5

-20 / 8 = -2.5

We can see that every new term is -2.5 times bigger than the previous term.

Hence to find the next term,

we multiply -20 by -2.5:

(-20)(-2.5) = 50.

Hence 50 should go into the box.

Answer:

50

Answer:

x = 8/3

Step-by-step explanation:

3x + 16 = 24

3x = 24 - 16 (subtract 16 from both sides)

3x = 8

x = 8/3 (divide both sides by 3)

Step-by-step explanation:x<-5/2

Answer:

15 feet

Step-by-step explanation:

The ladder is the hypotenuse of a right triangle, with the legs being 9 ft and 12 ft long (see the picture).

To solve for the length of the ladder, use the Pythagorean Theorem.

[tex]9^{2} +12^{2} =c^{2} \\c=\sqrt{9^{2} +12^{2}} \\c=\sqrt{81+144} \\c=\sqrt{225} \\c=15[/tex]

Answer:

So we know that y=1/2x. So we apply this equation on each x.

x=-2, so y=1/2*-2 which is -1. so y = -1

x=0, so y = 1/2 * 0 which is 0. so y=0

x=2, so y = 1/2*2 which is 1. so y=1

Hope this helps :))

Answer:

15 months

Step-by-step explanation:

35x+20=545

Subtract 20 from both side to figure out how many months he paid for....

35x+20-20=545-20

35x=525

Divide 35 on both sides....

x=15

Therefore, he has been a member for 15 months

Check:

35(15)+20=545

525+20=545

545=545

IT'S CORRECT!!!

MARK ME BRAINLEST PLS THANKS :)

Answer:

F: 12r+y

Step-by-step explanation:

- Why not G because if you multiple 2 by 6 and you get 12 then why not multiple the 6 too.

- Why not H because how do you get 16???

- Why not J because you don't add 2 pulse 6 to make 8 when you are supposes to multiple.

Hope this helps and sorry if wrong :)

Answer:

10 weeks

Step-by-step explanation:

12 * 3 = $36 At this point of 3 weeks you will be out of debt.

$12 * 7 weeks = $84 At  this point you will be a dollar short, but you had a dollar left over after 3 weeks. This would put you at a total of $85.

So, it would take 3 weeks to get out of debt and 7 to get up to $85.

3 + 7 = 10

A= 10 weeks

Hope this helps! :)

Answer: Answer choice B

Answer:

x = 8 and y = - 1

Step-by-step explanation:

The equation of a vertical line parallel to the y- axis is

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (8, - 1 ) with x- coordinate 8, then

x = 8 ← equation of vertical line

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through

The line passes through (8, - 1 ) with y- coordinate - 1, then

y = - 1 ← equation of horizontal line

Answer:

Teo is 8 years old and Richard is 29 years old

Step-by-step explanation:

Let us solve the question

Assume that Teo is x years old

∵ Teo is x years old

∵ Richard is 13 years older than twice Teo's age

→ It means multiply x by 2, then add 13 to get the age of Richard

∴ Richard's age = 2x + 13

∵ Richard and Teo have a combined age of 37 years

→ Add their ages and equate the sum by 37

∴ x + 2x + 13 = 37

→ Add the like terms

∵ (x + 2x) + 13 = 37

∴ 3x + 13 = 37

→ Subtract 13 from both sides

∵ 3x + 13 - 13 = 37 - 13

∴ 3x = 24

→ Divide both sides by 3 to find x

∴ x = 8

∵ x represents Teo's age

∴ Teo is 8 years old

→ Substitute the value of x in the expression of Richard age to find his age

∵ Richard age = 2(8) + 13 = 16 + 13 = 29

∴ Richard is 29 years old

∴ Teo is 8 years old and Richard is 29 years old

Answer: x = 5, y = 2/5

Step-by-step explanation:

We have the system of equations:

6*x + 5*y = 32

2*x + 5*y = 12

To solve it, we can start by isolating one of the variables in one of the equations.

Because in both of them we have the term 5*y, i will isolate 5*y in the second equation:

5*y = 12 - 2*x

Now let's replace it in the first equation:

6*x + (12 - 2*x) = 32

Now let's solve it for x

6*x + 12 - 2*x = 32

(6*x - 2*x) = 32 - 12 = 20

4*x = 20

x = 20/4 = 5

Now we know the value of x, we can replace it in the equation:

5*y = 12 - 2*x

to find the value of y.

5*y = 12 - 2*5

5*y = 2

y = 2/5

Then the solution of the system is x = 5, y = 2/5
