Write the phrase as an algebraic expression. The quotient of twelve and the difference of three and a number (Type an expression using x as the variable.)
Answer:
The answer is 12 + 3 - x
Step-by-step explanation:
The keywords are "and" and "difference". "And" means adding and "difference" means subtracting. And if the phrase says/or writes a number before any keywords that represent an operation then, it means that number comes first before the sign or operation.

Subtract-8/11 from -17/11
Answer:
the answer will be -0.81818181818
hope this helps!pls mark me as the brainliest!
The required subtraction of -8/11 from -17/11 has the outcome of -9/11.
Given that, determine the subtraction of -8/11 from -17/11.
According to the statements, mathematics deals with a variety of operations. The four main operations in mathematics are addition, subtraction, multiplication, and division.
What is simplification?In mathematics, the operation and interpretation of a function to make it simple or easier to grasp is known as simplifying, and the process is known as simplification.
Here,
according to the question,
= -17/11 - (-8/11)
= -17/11 + 8 / 11
= [-17 + 8] / 11
= -9 / 11
Thus, the required subtraction of -8/11 from -17/11 has the outcome of -9/11.

A third alternative to the formulas I suggested in a comment is to use the vector cross product. Recast the three given points as points in 3D space with 0 z-coordinate:
A(20, 21, 0), B(8, 29, 0), and C(13, 1, 0)
Now consider two vectors,
u = B - A = 〈8, 29, 0〉 - 〈20, 21, 0〉 = 〈-12, 8, 0〉
v = C - A = 〈13, 1, 0〉 - 〈20, 21, 0〉 = 〈-7, -20, 0〉
Then recall the cross product identity,
||u × v|| = ||u|| ||v|| |sin(θ)|
where θ is the angle between the two vectors. The magnitude of u × v is equal to the area of the parallelogram spanned by u and v, and hence twice the area of the triangle of interest.
So we have
area = ||1/2 〈-12, 8, 0〉 × 〈-7, -20, 0〉||
area = 1/2 ||〈-12, 8, 0〉 × 〈-7, -20, 0〉||
area = 1/2 ||〈0, 0, 296〉||
area = 296/2
area = 148

Answer: x = 30°
Concept:
Here, we need to know the idea of an isosceles triangle and the vertical angle theorem.
An isosceles triangle is a triangle that has any two of its sides equal to each other. Also, the angles opposite these equal sides are equal, which is basically the base angles.
The vertical angle theorem states that two vertical angles formed when two lines intersect each other are always equal to each other.
Solve:
Find the other base angle of the isosceles triangle.
Since there are two equal sides, we know that this is an isosceles triangle.
Since the definition said that the base angles are equal, the other base angle would also be x.
Find the value of x
According to the vertical angle theorem, two vertical angles formed by intersection are equal.
Just as angle x and 30°, are vertical angles formed by intersection, therefore, [tex]\boxed{x=30}[/tex]

Ramesh buys 10 containers of juice from one shop and 18 containers of the same juice
from another shop. If the capacity of each container is same and the cost of each of the
container is ₹150, find the total money spend by Ramesh.
4200
Step-by-step explanation:
10 × 150 = 1500
18 × 150 = 2700
So
1500 + 2700 = 4200
2. Which number line is correct? Why are the others incorrect?
Answer:
the middle one is correct
Step-by-step explanation:
the first one is incorrect because the way negative numbers are ordered is incorrect it should be "-3, -2, -1"
the middle one is correct because the pattern is consistent and the order of the numbers are correct
the third one is incorrect because the pattern doesn't match "-15" isn't counting by twos 15 isn't an even number
hope I helped ❤
Explanation:
The first number line is incorrect because the -1, -2, -3 should be reversed to get -3, -2, -1. It's reversed because the negatives are a mirror image of the positive counterpart.
The second number line is correct. Each number shown is separated with a gap size of 20. This gap size stays the same throughout the number line.
The third number line is incorrect. The gap from -15 to -12 is 3 units, while the gap from -12 to -10 is 2 units. We see that the gap size isn't the same through the entire number line.
So to summarize: the gap size must be the same and the numbers must be written in the correct order.

Wendy and Jason, the boy she was babysitting, were playing basketball together. Her score
was 30 points, and his score was 20 points. Wendy wanted to make the game more fair, so
she called a time-out and modified the rules a bit. Wendy explained that, for the rest of the
game, she would get 2 points per basket, and Jason would get 3 points per basket. Then they
played a bit longer. After the time-out, they both made the same number of baskets and
ended up with a tied score. How many points did each person have at the end?
Write a system of equations, graph them, and type the solution.
Answer:
They both scored 50 points
Step-by-step explanation:
2x + 30 = 3x + 20
(Combine like terms)
-x = 20 -30
-x = -10
x = 10
