The following figure is not drawn to scale.

1) Using complete sentences, describe how angle relationships can be used to find the value of in this figure. Then, find the value of x, showing all of your work.
2) Using complete sentences, describe how angle relationships can be used to find the value of y in this figure. Then, find the value of y, showing all of your work.

Answers

1) The sum of all the angles in a triangle is always 180 degrees, so to find x, you can set up an equation with the provided angles and solve.

45+60+x=180

105+x=180

x=75

2. x degrees and y degrees add up to 180 degrees, because they form a straight angle, which is a straight line. You can set up an equation using the value of x you found in the previous part and solve for y.

x+y=180

75+y=180

y=105

what are the like terms in the expression 2y + 3x + y + 2x + 4

Answers

Answer:

2y and y are like terms

Because all of the numbers here have a variable, 4 is not a like term. The number 4 is the only one that doesn't have it.

2x and 3x as well as 2y and y. Although the numbers aren’t the same, the variables are the same and you can add two x’s together and two y’s together

Simplify the expression 4(2x + 8) using the distributive property.

Answers

Answer:

[tex]8x + 32[/tex]

Step-by-step explanation:

[tex]4(2x+8)[/tex]

4 × 2x = 8x

4 × 8 = 32

[tex]8x + 32[/tex]

Simplify the expression 4(2x + 8) using the distributive property.

The distributive property tells us how to solve expressions in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. ... Then we need to remember to multiply first, before doing the addition!

Hence, the information sho above we can now solve the equation

4(2x + 8) without any problem.

4(2x + 8) --->   4 * 2x + 4 * 8  ---> 8x + 32

Therefore, your finnal answer is  

8x + 32

1/4 of 35=8.75 so about 9

Step-by-step explanation:

Answer:

20 Chocolate cupcakes and 15 vanilla cupcakes.

Step-by-step explanation:

Use c for chocolate cupcakes and v for vanilla cupcakes.

3/4c=v

c+v=35

Use substitution

c+3/4c=35

1 3/4c=35 or 7/4c=35 --> Multiply by reciprocal

c=20

Plug it into an equation

20+v=35

v=15
