What is Algebra?Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.
We have to find an algebraic expression which represents the phrase "seven more than half of a number".
Consider a number x,
half of x = (x/2)
seven more than half = (x/2) + 7
Hence, seven more than half of a number is (x/2) + 7.

all you really need to do is find the common denominator and it'll get you an answer for the numerator.
Answer:
13/15
Step-by-step explanation:
You first need to find the common denominator between both 3 and 5, so you have to find the number that would be the best, which is 15. Then you have to multiply the numerator by how many times you went up for that number, for 2/3 would be times 5, and 1/5 would be times 3. Doing this will get you your answer, 13/15.
1. Given a = 18, A = 105 degrees, and B = 32 degrees, use the Law of Sines to solve for b. Round your answer to the nearest tenth, and enter the number only.
2. Given c = 20, C= 101 degrees, and b = 14, use the Laws of Sines to solve for B. Round your answer to the nearest degree.
3. Given a= 100, A= 80 degrees, and b = 61, use the Law of Sines to solve for B. Round your answer to the nearest degree.
Answer:

Answer:
Step-by-step explanation:
Start with this equation where 17 is the base, x is the power that 17 must be raised to. Then 2 is the result.
17^x = 2 Take the log of both sides
log(17^x) = log(2) Take the x outside the brackets
x log(17) = log(2) Divide by log 17
x = log(2)/log(17) Find the values for log 2 and log 17
log(2) = 0.3010
log(17) = 1.230
x = .3010/1.230
x = .2446

The sum of a number x and 4 is less than 12.
Which of the following inequalities represents this
statement?
Answer:
x+4<12
Step-by-step explanation:
You did not put the inequalities, but that is how the statement would look like. "And" is a clue that we're adding. So, x + 4 would be the first part, and we know when the open part of this symbol '</>' is pointed at a number then that number is greater than the number before it. So, in this case, you'll want to have that symbol pointed at 12 because x + 4 is less than 12.
one leg of a right triangle is 21 centimeters long. The hypotenuse of the triangle is 29 centimeters long. What is the length of the unknown leg?
Answer:
20 cm
Step-by-step explanation:
A2 + B2 = C2
C is your hypotenuses = 29 cm
And one leg of a right triangle is 21 cm long
So we have A2 = (21cm)2 = 441 cm + B2 = (29cm)2 = 841cm
B2 = 841 - 441 = 400
B = √400 = 20
So the third leg of a triangle that has a hypotenuses of 29 cm and one side of a right triangle that is 21 cm long is 20 cm
Cynthia paid $30 for herself and her 2 friends at the movies. Each person had a movie ticket, a bag of popcorn for $2, and a drink for $1. Cynthia had a coupon for $7.50 off. What was the original price of each ticket?
Answer:
9.5 dollars per ticket
Step-by-step explanation:
to start you have to add 7.5 to 30 dollars to get how much it would have cost normally you get 37.5. next subtract 9 dollars. 6 for the popcorn and three for the drinks. you get 28.5 then devide by three to get the cost of one ticket at 9 dollars and 50 cents hope this helped. if you have any more questions feel free to message me
Answer:
$7.50
Step-by-step explanation:
She paid $30 for herself(1) and 2 friends = 3 tickets
30-6(popcorn)=24-3(drinks)-22+7.50=29.50/3= $7.50

Pls help i dont understand :(
Answer:
The answer is B.
Step-by-step explanation:
The answer is B, because if you have a vertical line, it is undefined. And also, it is on the x-axis, therefore it would be x = 4.
Answer
b. x=4, undefined
Step-by-step explanation:
the x value constantly stays at 4 because it’s a straight vertical line. there’s no slope because it’s straight up and down.

Phoenix has 11200 registered voters. There are two candidates for city council in an upcoming election: A and B. The day before the election, a telephone poll of 400 randomly selected registered voters was conducted. 138 said they'd vote for A, 228 said they'd vote for B, and 34 were undecided. We will assume the actual voting results will be proportional to this survey.
This voter sample suggests that we might expect ______________of the 11200 registered voters to vote for A.

solve this 59 + x = 24
Hey there!
=> 59 + x = 24
=> x = 24 - 59
=> x = -35
Therefore, 59 + (-35) = 24
Answer:
[tex]\boxed{\sf{x=-35}}[/tex]
Step-by-step explanation:
A subtraction property of equations is the subject of this problem.
For the correct answer, you need to isolate x from one side of the equation.
59+x=24
First, switch sides.
x+59=24
Then, subtract by 59 from both sides.
[tex]\sf{x+59-59=24-59}[/tex]
Solve.
[tex]\sf{24-59=-35}[/tex]
[tex]\boxed{\sf{x=-35}}[/tex]
Therefore, the solution is x=-35, which is our answer.
I hope this helps you! Let me know if my answer is wrong or not.
