Select all of the equations that are equivalent to `3x+45=180`.
A. 3 (x + 45) = 180
B. 3 (x + 15) = 180
C. 3 (x + 15) = 60
D. x + 15 = 60
E. 3x = 135

Answers

Answer:

Option B and Option D

Step-by-step explanation:

B = 3*x = 3x, 3*15 = 45.

D=3* x + 15.

3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

We have to solve the equation  3x+45=180

Now isolate x on one side of the equation.

We can do this by subtracting 45 from both sides, giving us 3x=135, and then dividing both sides by 3 to get x=45.

Therefore, the equivalent equations are:

3x = 135

x + 15 = 60

Hence, 3x = 135 and x + 15 = 60 are the equations that are equivalent to 3x+45=180

Answers

Answer:

Solve for x first.

In order to solve for x, you must set up an equation where the two interior angles (1 and 2) are equal to the exterior angle (3).

Interior angles.

Angle 1 = 3x + 7Angle 2 = 2x + 24

Exterior angle:

Angle 3 = 6x + 10

Set up the equation:-

(3x + 7) + (2x + 24) = 6x + 10

Group and combine like terms;

(3x + 2x) + (7 + 24) = 6x + 10

5x + 31 = 6x + 10

Get rid of constants;

-10             -10

5x + 21 = 6x

-5x         -5x

21 = x, the value of 'x' is 21°.

Now we plug in the value of x into angle 3's equation.

∠3 = 6x + 10

∠3 = 6(21) + 10

∠3 = 126 + 10

∠3 = 136°, ∠3 = 136°.

C=32

Step-by-step explanation:

500*8=4000

70*8=560

8*4=32

Answer:

A = 4000

B = 560

C = 32

574 x 8 = 4592

Step-by-step explanation:

To find the area of A, we must multiply 500 by 8 because those are the dimensions.

500 x 8 = 4000

Therefore, A = 4000

To find the area of B, we must multiply 70 by 8.

70 x 8 = 560

Therefore, B = 560

To find the area of C, we must multiply 4 by 8.

4 x 8 = 32

Therefore, C = 32

To find the total area, we can add the area of A, B, and C together.

4000 + 560 + 32 = 4592

By examining this image:

  ⇒ we see a right triangle made up of sidelength of h, 8, and 17

     ⇒ we know this is a right triangle because there is a little square

         ⇒between lines of length 8 and h

            ⇒ which indicates this angle is 90 degrees

               ⇒ which indicates we have a right triangle

Since we have a right triangle

   ⇒ we can use the Pythagorean Theorem

Definition of Pythagorean Theorem: square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

           *look at the image attached for a better explanation

Now let's form an equation (based on the Pythagorean Theorem)

Answers

part a answer is the first triangle

Answer:

The 1st choice

Step-by-step explanation:

(a) the first and second ones are the only triangles with all three acute angles. The 2nd one has more than 1 line of symmetry so the 1st must be the answer.
(b) This one really depends on which side of the triangle is each length. One way to do it is A squared + B squared = C squared. 8 equals c because it is the largest side and 7.5 is A. This would be put out like 56.25 + B = 64. Subtract 56.25 from both sides to get B = 7.75.
OR, if 8 is not the longest side 7.5 squared + 8 squared = C squared which would be 120.25 = C squared. So, you would find the square root of 120.25 which is 10.97.

10 POINTS) A recipe requires 4.5 teaspoons of sugar to make a cup of pudding. Which equation shows the number of teaspoons of sugar, y, needed to make x cups of pudding?
x = 4.5y
y = 4.5 + x
y = 4.5x
x = 4.5 + y

Answers

Answer:

C. y = 4.5x

Step-by-step explanation:

The recipe calls for 4.5 teaspoons of sugar to make each cup of pudding. To make 2 cups of pudding, we would need two groups of 4.5 teaspoons, or 4.5+4.5=9 teaspoons of sugar. To make 3 cups of pudding, we would need 3 groups of 4.5 teaspoons, or 4.5+4.5+4.5=13.5 teaspoons of sugar. This repeated addition can be simplified as multiplication, because 4.5+4.5=4.5*2. We will need y teaspoons of sugar to make x cups of pudding. For each cup of pudding, we need 4.5 teaspoons of sugar. So, y=4.5x. If we made 2 cups of pudding (meaning x = 2 now), we fill that in and solve for y, which equals 9, as seen at the start.

Answer:

C.  y = 4.5x

Answer:

A = picture attached

B = 51 in²

Step-by-step explanation:

I answered your other question, and I'm feeling lazy, so let me just copy + paste my answer here.

The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.

Area of the triangle = 1/2 (base × height)

A = 1/2 (4 × 6) = 1/2 (24) = 12

The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.

Area of rectangle = length × width

A = 5 × 2.5 = 12.

Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie

A = 6 × 2.5 = 15

Add the areas altogether to get the answer.

24 + 12.5 + 15 = 51.5 in²

I hope this helps. Sorry if Part B's answer is wrong.

Answer:

x = 6

Sorry if this answer is not correct, if it is or is not, please tell me in the comments!

Step-by-step explanation:

All of the angles add up to 180 degrees (since it is a triangle), so

(11x - 3) + (7x + 5) + (13x - 8) = 180

Then, combine the like terms.

31x - 6 = 180

Now, out goal is to separate the x from everything. To do that, we need to add 6 to 180.

31x = 186

Then divide by 31.

x = 6

(Feel free to replace x with 6 back in the previous equation to double check it!)

x = 6
because the the whole triangle equals 180 degrees
so you have to add all the equations and equal it to 180
