Answer:

y = 5

Step-by-step explanation:

ok so we dont really need to know what x is unless they ask for it but ill do it anyways

B angle and C angle are equal so...

B = 75

75 = (3x)

75 / 3 = 25

x = 25

a triangles angles equals 180 degrees

75 + 75 = 150

180 = 150 + ?

180 - 150 = 30

A = 30 degrees

4y + 10 = 30

get the y on it's own side

4y + 10 - 10 = 4y

30 - 10 = 20

4y = 20

4y / 4 = y

20 / 4 = 5

y = 5

Answer:

z = 100°

x = 40°

Step-by-step explanation:

Triangle CBD is isosceles so there are two 50°

DBC = 50°

That means BDC = 80° because 180(sum of angles in triangle) - 50 - 50 = 80

Z = 100° bc angle of straight line is 180° and 180 - 80 = 100

Now triangle ADB is also isosceles because there are two sides of equal length

So there will be 2*x + 100 = 180

x = 40°

First of all, you won't be able to simplify it all the way.

Second, you have to subtract 2x-8x, because they are common terms.

2x-8x=-6x

So the simplified expression is -6x+1

Answer:

8/9

Step-by-step explanation:

Repeating. Just do 8 divide by 9

Answer:

75.5

Step-by-step explanation:

9,524 divided by 126 is equal to 75 with a remainder of 30.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To perform the division of 9,524 by 126, you can use long division as follows:

 126 | 9,524 | 75

      882

      ---

      1124

     1008

     ----

      1164

     1134

     ----

        30

In other words:

9,524 ÷ 126 = 75 R 30

Therefore,

9,524 divided by 126 is equal to 75 with a remainder of 30.

Answer:

x=1/3

Step-by-step explanation:

Factor out 5^3x

5^3x(1-1/5)=4

Combine the fractions

5^3x(4/5)=4

Multiply both sides by 5/4

5^3x=5

Now we have the same base of 5 so we can set the exponents equal to one another (the exponent of 5 is 1)

I believe it is because it is being transferred to kinetic energy

Step-by-step explanation:

As the puck falls, it loses potential energy and gains kinetic energy because it is now falling, which causes movement due to gravity. And as we know, kinetic energy is energy which a body possesses by virtue of being in motion

Answer:

1/2 ÷ 4 = 8

Step-by-step explanation:

Dividing fractions is as easy as pie. Flip the second and multiply.

1/2 ÷ 4 = 1/8

A whole number secretly has a 1 underneath, like this: 4/1

Flip the second number over to get 1/4, then multiply straight across.

[tex]\frac{1}{2}[/tex] × [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{8}[/tex]

Try to do the same for the other answers and see if they're right (they're not).

1/8 x 1/6 = 1/48

1/3 x 1/4 = 1/12

1/9 x 1/2 = 1/18

Answer: 35 inches.

Step-by-step explanation:

We know that:

hypotenuse = 5*y in

cathetus 1 = (x + 8) in

cathetus 2 = (x + 3) in

The perimeter of the triangle is 76 inches, then:

5*y + (x + 8) + (x + 3) = 76

5*y + 2*x + 13 = 76

We also know that the length of the hypotenuse minus the length of the shorter leg is 17 in.

The shorter leg is x + 3, then:

5*y - (x + 3) = 17

Then we have the equations:

5*y + 2*x + 11 = 76

5*y - (x + 3) = 17

With only these two we can solve the system, first we need to isolate one of the variables in one of the equations, i will isolate x in the second equation.

x = 5*y  - 3 - 17 = 5*y - 20

x = 5*y - 20

Now we can replace this in the other equation, we get:

5*y + 2*x + 11 = 76

5*y + 2*(5*y - 20) + 11 = 76

15*y - 40 + 13 = 76

15*y - 29 = 76

15*y = 76 + 29 = 105

and remember that the hypotenuse is equal to 5*y, then we want to get:

3*(5*y) = 105

5*y = 105/3 = 35

5*y = 35

Then te length of the hypotenuse is 35 inches.
