What is the value of x?
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!

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Joyce has scored 90, 93, and 85 on the first three. What range of scores on the fourth test will give Joyce a C for the semester (an average between 70 and 79, inclusive)? Assume that all test scores have a non-negative value.
Express your answer in interval notation.
HELP ASAP BRAINLEST AND THANKS
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]

please HELP MEEEEEE .A store owner wants to make a candy that sells for $1 per pound.he has 50 lb of sugar candies that cost $1.20 per pound.how many pounds of gummy candies that cost 80 cents per pound should he add.
Answer:
50 pounds
Step-by-step explanation:
we can use the equation 60+80/100x=1(x+50)
we get 80/100 x because the gummy candies are 80 cents or 80/100x
we get 60 from multiplying 1.20$ 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.
What is a proportion?A proportion is a fraction of a total amount.
This problem is organized as follows:
There is a total of 50 + x pounds.Of those, 50 cost $1.2 per pound.x cost $0.8 per pound.The selling price is of $1.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.
