Answer:
X=115°
Step-by-step explanation:
If you extend the line on the left up to the top, it forms a triangle. The three interior angles of that triangle are 50, 180-x, and 180-x.
50+180-x+180-x=180
410-2x=180
410-180=2x
230=2x
x=115°
Another way to look at it: Since two of the angles in the triangle are the same, they must total 130. (180-50=130)
130 ÷2 equals 65. If those angles are 65, x=180-65=115°

If Maya orders a $1.89 drink, 3 cookies at $.99 each, and 2 slices of pizza at $2.50 each. How much did Maya pay for her order?
ASAP PLZ IM DOING A TEST
Answer:
$9.86
Step-by-step explanation:
Frist you read the problem and you see that she pays $1.89 for one drink
so you write down $1.89
then 3 cookies for $0.99 so you multiply $0.99 by 3 and you get $2.97
so you write down $2.97
next 2 slices of pizza for $2.50 so you multiply 2 by $2.50 and you get $5.00
so you write that down
lastly you and the answers you wrote down and you get $9.86
Maya payed $9.86 for her order.

Nancy is the proud owner of a new car. She paid $1,500 up front and took out a loan for the rest of the amount. The interest rate on the loan is 5%. If the total cost of buying the car (including the interest Nancy owes) is more than $16,213.02, how much money did Nancy borrow?
-------------
Part A
Assume that X represents the amount of money Nancy borrowed. Write an expression that represents the amount borrowed (the principal) plus the interest owed on that amount.
Part B
Write an expression to represent Nancy’s total cost of buying the car.
Part C
Write an inequality using the expression from part B to represent this scenario.
Part D
Solve the inequality for the variable x. Use opposite operations on both sides of the inequality until you get x on one side of the inequality by itself.
Part E
What does the result from part D tell you about Nancy’s situation?
Part F
Think about graphing the inequality you found in part D on a number line. What would it look like?

Please help and show work for this
Answer:
2 dollars for kids
5 dollars for adults
Step-by-step explanation:
We will let x= children
y= adult
we know that
33x+42y=276
46x+40y=292
There are a lot of ways you can solve this but I think it's easiest if we use (what I think is called elimination)
we will start by mulitiplying the second equation by 1.05 to get
48.3x+42y= 306.6
We will subtract the first equation from the second to get
15.3x= 30.6
Solve for x and get 2
Now that we know what x equals we can plug that into any equation and solve for y
we have
33(2)+42y=276
y=5

Franco has 7/8 of an ounce of gold. He wants to give 3/16 of an ounce to his friend, Julie. He plans to divide the rest in half to make two rings. How much gold will he have for each ring. (answer with explanation will get Brainliest.)
Answer:
He will have 11/32 of an ounce for each of the two rings.
Step-by-step explanation:
He starts with 7/8 of an ounce.
He gives 3/16 of an ounce to Julie.
7/8 - 3/16 = 14/16 - 3/16 = 11/16
He now has 11/16 of an ounce left.
Now he divides 11/16 of an ounce in half.
(11/16) / 2 = 11/16 * 1/2 = 11/32
He will have 11/32 of an ounce for each of the two rings.

What is the slope of y = -5 – 41?
Answer:
4
Step-by-step explanation:
We need to rewrite this in slope-intercept for which is
y=mx+b
So switch 4x and -5
y=4x-5
m is slope and b is y-intercept we need to find the slope so we look what is beside x which is 4 so the slope is 4

Since the degree of the numerator is less than the degree of the denominator, we don't need to divide. We factor the denominator as
Answer:
As given,
I = [tex]\int\limits {\frac{3x}{x^{2} - 2x} } \, dx[/tex]
Since the degree of the numerator is less than the degree of the denominator, we don't need to divide.
We factor the denominator as x(x-2)
The partial fraction decomposition is
[tex]\frac{3x}{x^{2} - 2x} = \frac{3x}{x(x-2)} = \frac{A}{x} + \frac{B}{x-2}\\ = \frac{A(x-2) + B(x)}{x(x-2)} \\[/tex]
we get
3x = A(x-2) + B(x)
⇒3x = x(A+B) - 2A
By comparing , we get
A+ B = 3 , -2A = 0
⇒A = 0 and B = 3- A = 3-0 = 3
∴ we get
A = 0, B = 3
Therefore, the integral become [tex]\int\limits {\frac{3x}{x^{2} - 2x} } \, dx = \int\limits {[\frac{0}{x} + \frac{3}{x-2} ] } \, dx[/tex]
18% of the the students at a school are in year 8 and 16% of the students are in year 9. If the school has 126 tera 8 students, determine the number of year 9 students.
Answer:
112
Step-by-step explanation:
The general form of all percentage questions is: the chunk= (some percentage) (of the whole), or c=p*w
We know that 18% of students are 8th grade and that is 126 students, so p = 0.18 and c=126 (126 students are 18% of the whole school)
126 = (0.18)w, divide both sides by 0.18
126/(0.18) = w = 700
9th graders are 16% of the school or 16% of 700 students
c = (0.16) 700 = 112 students

Answer:
B
Step-by-step explanation:
So far, we know that:
∠D = ∠J.
And that:
DE:JK = 14:7 = 2:1
So, to prove that ΔDEF ~ ΔJKL by SAS, DF must be similar to JL, as those are the sides between the angle.
So:
DF:JL = 2:1.
Our answer is B.
