I don’t k is how to do this stuff

Answer:

y = 2

Step-by-step explanation:

x= -1+y

2x-y=0

2(-1+y)-y=0

-2+2y-y=0

-2+y=0

-2+2+y=0+2

y=2

hope it's helpful ❤❤❤❤

THANK YOU.

Answer:

[tex]2( - 1 + y) - y = 0 \\ - 2 + 2y -y = 0 \\ y = 0 + 2 \\ y = 2 \\ x = - 2[/tex]

Answer:

B, 606,900

Step-by-step explanation:

First you'll need to calculate the percentage growth after 32(2030 - 1998) years. to do this you'll need to find 1.11^32 or 28.205, 1.11 being the percentage growth per year and 32 being the number of years passed. then 21,517*28.205 = 606,899.8 which can be rounded to 606,900.

Answer:

x = 4

y = 3

Step-by-step explanation:

2x - 3(x - 1) = -1

2x - 3x + 3 = -1

-x + 3 = -1

   - 3     - 3

(-1) -x = -4 (-1)

x = 4

y = 4 - 1

y = 3

Answer:

x = 4, and y = 3

Answer:  A.) The area of the base is 16 pi cm²,

B.) The number of cubic centimeters is 112 pi cm³

C.)  The volume is  351.68 cm³

Step-by-step explanation:

Area is πr², 4 squared is 16.

V = bh

Multiply the area of the base by the height

16π × 7 = 112pi

Answer:

x = 6

Step-by-step explanation:

The inscribed angle is half the measure of its intercepted arc, that is

3x + 5 = 0.5 × 46 = 23 ( subtract 5 from both sides )

3x = 18 ( divide both sides by 3 )

x = 6

Answer:

x = 6

Step-by-step explanation:

The inscribed angle is half the measure of its intercepted arc, that is

3x + 5 = 0.5 × 46 = 23 ( subtract 5 from both sides )

3x = 18 ( divide both sides by 3 )

x = 6

Answer:

15.7 inches

Step-by-step explanation:

A clock is a circle .  It tells us that the radius of the circle is 2.5 inches, and it is asking for the circumference.  Therefore, we can use the equations for a circle to solve for the circumference.

[tex]Circumference=2\pi r\\C = 2 \pi (2.5)\\C = 15.708[/tex]

Answer:

x =7

Step-by-step explanation:

To solve this, you must get x by itself.

3x-5 = 16      1.  Add 5 on both sides

3x = 21         2. Divide by 3 on both sides

x = 7

Answer:

m = [tex]\frac{13}{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{12}[/tex] = [tex]\frac{m-4}{4}[/tex] ( cross- multiply )

12(m - 4) = 4 ( divide both sides by 12 )

m - 4 = [tex]\frac{4}{12}[/tex] = [tex]\frac{1}{3}[/tex] ( add 4 to both sides )

m = 4 [tex]\frac{1}{3}[/tex] = [tex]\frac{13}{3}[/tex]

Answer:

There are 9 girls in the class and 17 boys in the class

Step-by-step explanation:

Set up a system of equations where b is the number of boys and g is the number of girls

b + g = 26

b = g + 8

Solve by substitution by substituting g + 8 as b into the top equation

b + g = 26

(g + 8) + g = 26

2g + 8 = 26

2g = 18

g = 9

So, there are 9 girls in the class. There are 8 more boys than girls, so add 8 to this to find the number of boys:

9 + 8

= 17

So, there are 17 boys.

There are 9 girls in the class and 17 boys in the class.
