Answer:

x=1 y=14

multiply x-y=-13 by 3 so the x would cancel out. solve for y

then plug in y to one of the equations to get x

Answer: the answer is x= -2 , y=11

Step-by-step explanation:

First

1: we have to find the answer for x in x-y= -13

2: add y on both sides of the equation

3: we will get x= -13+y

Second

1: Substitute x in 3x-y= -17 with x=-13+y

2: then you will get 3(-13+y)-y= -17

3: multiply 3 with -13 and y

4: you will get -39+3y-y =-17

5: add 3y and -y

6: you will get -39+2y= -17

7: add 39 on both sides of the equation

8: you will get 2y=22

9: divide 2 on both sides

10: you will get y= 11

Third

1: plug 11 for y in x= -13+y

2:  then you will get x= -13+11

3:  you will x= -2

So x= -2 and y= 11

Answer:  X=9-y

Step-by-step explanation:

Answer:

x = 9 - y

y = 9 - x

Step-by-step explanation:

[tex]3(x + y) = 27[/tex]

[tex]x + y = \frac{27}{3} [/tex]

[tex]x + y = 9[/tex]

[tex]x = 9 - y[/tex]

[tex]3(x + y) = 27[/tex]

[tex]x + y = \frac{27}{3} [/tex]

[tex]x + y = 9[/tex]

[tex]y= 9 - x[/tex]

Hence, the answer for x is x = 9 - y and the answer for y is y = 9 - x.

Answer:

The distance around a circle on the other hand is called the circumference (c).

Step-by-step explanation:

A straight line that passes from one side of a circle to the other through the center is called the diameter. The distance around the outside of a circle is called the circumference. All points on the edge of a circle are the same distance to the center.

The length of the outside of a circle is called the "circumference."

The circumference is the total distance around the outer boundary of the circle.

The distance cover while completing one full lap around the track is equivalent to the circumference of the circle.

The formula to calculate the circumference (C) of a circle is:

C = πd

where π (pi) is a mathematical constant equal to 3.14159, and d represents the diameter of the circle.

The formula for circumference in terms of the radius is:

C = 2πr

Answer:

the first one....

6=w+2.

Image of figure is missing so i have attached it.

Answer:

The total length of three sides of the square = 36 in

Side length of square = 12 in

A_triangle = 48 in²

Area of square = 144 in²

Total area of figure = 192 in²

Step-by-step explanation:

Total perimeter = 56 inches

Let the side of the square be s.

Thus, perimeter of the 3 sides of the square = 3s

Therefore, adding all the external sides of the figure, we have;

3s + 10 + 10 = 56

3s + 20 = 56

3s = 56 - 20

3s = 36

s = 36/3

s = 12

Area of triangle is given by the formula;

A_triangle = ½bh

Where;

b is base

h is height

Thus;

A_triangle = ½ × 12 × 8

A_triangle = 48 in²

Area of square = 12 × 12 = 144 in²

Total area of figure = 144 + 48 = 192 in²

i think its that since im guessing that x5 is the length of each side and since triangles have 3 sides so i did 5 x 3 which equals 15

Step-by-step explanation:

when X is negative f(x) is positive. and when f(x) is negative x is positive

Answer:

These relationships are realted because the variable is multiplied by ten to get the function.

9cm: 90mm

12 1/4cm: 122.5mm

50cm: 500mm

88.49cm: 884.9mm

By the way, can you follow me on Brainly?

Thanks!

To find the area of a triangle we use this equation:

[tex]\frac{1}{2} bh\\[/tex]

b= base

h= height

So since we are given the information that the sides are 6 and the height is 5 we simply can plug the information right into the equation:

[tex]\frac{(6)(5)}{2}[/tex]= 15

So the are is 15 inches sqaured, hope this helps :)

Answer: 7.5 batches

Step-by-step explanation:

60/6 is 10, so she needs to make 10 batches in total.

10-2.5=7.5

Answer:

no. of muffins = 60 muffins

no of muffins in each batch = 6 muffins

no. of batches which got over = 2.5 batches

no. of muffins baked = 6 * 2.5 = 15

no. of muffins to be baked = 60 - 15 = 45

no. of batches required to bake 45 muffins = 45 / 6 = 7.5

hope this answer helps you!

step 4       9 divde by 2= 4.5

simplifyed it would be  25-16 ÷ 2

more deatialed explanation.

I added 3+2 to get 5 and i sqaured the 5 to get 25 becasue 5x5 is 25 then i took away 16 and got 9 then i divde 9 by 2 to get 4.5.  hope this helped!
