Answer:

x = 30 degrees

Step-by-step explanation:

Okay so we start by noticing that the two pointed out vertices = 180 degrees. So we have the following equation.

(x + 12) + (3x + 48) = 180

If you combine them you get:

4x + 60 = 180

Subtract 60 from both sides..

4x = 120

Divide both sides by 4..

x = 30

And there's your answer!

Step-by-step explanation:

Answer:

50 pounds

Step-by-step explanation:

we can use the equation           60+80/100x=1(x+50)

we get 80/100 x because the gummy candies are 80 cents or 80/100x

we get 60 from multiplying 1.20$ x 50 = 60

                                                    solve:

                        60+80/100x  =  x+50

                           60 = x-80/100x+50

                             60-50 = 20/100x

                              10 = 20/100x

                               x= 10 x 100/20 = 10x5= 50 pounds

Using proportions, it is found that he should add 50 pounds of gummy candies that cost 80 cents per pound.

A proportion is a fraction of a total amount.

This problem is organized as follows:

Hence:

[tex]\frac{50}{50 + x}1.2 + \frac{x}{50+x}0.8 = 1[/tex]

[tex]\frac{60 + 0.8x}{50 + x} = 1[/tex]

[tex]50 + x = 60 + 0.8x[/tex]

[tex]0.2x = 10[/tex]

[tex]x = \frac{10}{0.2}[/tex]

[tex]x = 50[/tex]

He should add 50 pounds of gummy candies that cost 80 cents per pound.

Step-by-step explanation:

Angles that add up to 90 are Complementary angles.

Two angles that have a common vertex and a common side but do not overlap are Adjacent angles.

Angles that are opposite each other and have the same measurment are vertical angles.

Angles that add up to 180 are Supplementary angles.

Answer:

[12,48]

Step-by-step explanation:

We will start by calculating the score she needs to get a 70 in the class

We will let x equal the fourth test

[tex]\frac{90+93+85+x}{4} =70[/tex]

This isn't hard to solve and we will do so by multiplying 4 by both sides and subtracting 268 (90+93+85)

This means that x= 12

We will then use the same formula but set it equal to 79

[tex]\frac{90+93+85+x}{4} =79[/tex]

We solve x in the exact same way and get x=48

our final answer is now [12,48]
