pleases help solve for x
Answers
Answer:
x = 31
Step-by-step explanation:
All of the angles in a triangle equal 180 degrees.
There is a 90 degree angle, and two unknown angles.
Your equation would be 90 + 2x - 2 + x + 5 = 180.
Combine like terms: 3x + 87 = 180.
Subtract 87: 3x = 93.
Divide 93 by 3 to cancel out x, and you get x = 31.
Explain what classifies a number as rational (your answer should specify what makes it rational as opposed to irrational).

Rational numbers are numbers that can be absolutely determined. This includes integers, limited decimals, repeating decimals, and fractions. Examples include 1, 1.25, 1.38383838..., and 1/2. Irrational numbers are numbers that cannot have their absolute value determined. This excludes every example for rational numbers. An example of an irrational number is 3.1415926535879...

Find the product of 6/9 and 3/8 . Express your answer in simplest form.A.6/24 B.1/6 C.18/72 D.1/4
Answers
Answer:
D.) 1/4
Step-by-step explanation:
6/9 x 3/8
6(3) /8(9)
= 18/72
18/18=1
72/18=4
= D.) 1/4
Answer:
D. 1/4
Step-by-step explanation:
First, we will multiply the numerator 6 × 3 = 18. Then, we'll multiply the denominators, 9 × 8 = 72. Then, divide 18 ÷ 18 = 1 and 72 ÷ 18 = 4. So there we go. the numerator is 1 and the denominator is 4. So the answer is 1/4 which is a proper fraction :) (mark this answer brainliest plz )

If P(x) = x ^ 2 + x + 3 and Q(x) = 4x ^ 2 - 3 find P(8) .
Answers
Answer:
75
Step-by-step explanation:
Giving Q was not necessary because you aren't doing P(Q) or anything like that....
Anyways,
[tex]p(x) = x^2 + x +3\\[/tex]
Since you're doing p(8), you would replace the x's with 8s.
[tex](8)^2 + (8) + 3 = 64 + 8 + 3 =75[/tex]
So your final answer would be 75.

Determine whether each equation has no solution, one solution, or infinitely many solutions.
Drag each equation to the correct location on the table.
Answers
Answer:
Step-by-step explanation:
No solution - 2y – 3 = 5 + 2(y – 1), one solution - (1/5)f – 2/3 = – (1/5)f + 2/3, 4a – 3 + 2a = 7a – 2, infinitely many solution - [-3(n + 4) + n = -2(n + 6)], -1.7v + 2.8 = 1.4v – 3.1v + 2.8.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
If the exponent of the variable is one, then one solution.
If both sides are zero, then no solution.
And if the variable is eliminated, then the infinitely many solutions.
-1.7v + 2.8 = 1.4v – 3.1v + 2.8, it has infinitely many solutions.
4a – 3 + 2a = 7a – 2
a = -1, it has one solution.
(1/5)f – 2/3 = – (1/5)f + 2/3
f = 5/3, it has one solution.
2y – 3 = 5 + 2(y – 1)
0 = 0, it has no solution.
-3(n + 4) + n = -2(n + 6), it has infinitely many solutions.

Joe is 14 years older than his cousin Tom.
Cousin Rob is 3 times as old as Tom. The sum of all
three of their ages is 64. Find each of their ages.
Answers
x = Tom's age
x + 14= Joe's age
3x = Rob's age
x + (x + 14) + 3x = 64
Let's combine like terms
5x + 14 = 64
Subtract 14 from both sides
5x = 50
Divide each side by 5
x = 10
Tom is 10 years old.
Joe's age = 10 + 14 = 24 years old
Rob's age = 3(10) = 30 years old

Answer:
y = 3x + 5
Step-by-step explanation:
The equation in slope- intercept form is
y = mx + c
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (2, 11) ← 2 ordered pairs from the table
m = [tex]\frac{11+1}{2+2}[/tex] = [tex]\frac{12}{4}[/tex] = 3, thus
y = 3x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (2, 11 ), then
11 = 6 + c ⇒ c = 11 - 6 = 5
y = 3x + 5 ← equation of linear function

I played 4 video games and had an average score of 12,000 points
per game. The average score of the first 3 games was 11,000 points
per game. How many points did I score in the 4th game?
Answers
Answer:
15,000
Step-by-step explanation:
The first three games leave you with at total that is 3000 below the average. So, the last game has a score that is 3000 above average:
12000 +3000 = 15000 points scored in 4th game
__
Check
(11000 +11000 +11000 +15000)/4 = 48000/4 = 12000
The average of anything is calculated by adding up all the values and dividing by the number of values.
The Average = 12,000
the # of values = 4
x = score of the 4th game
(11,000 + 11,000 + 11,000 + x) / 4 = 12,000
First, let's multiply both sides by 4
11,000 + 11,000 + 11,000 + x = 48,000
Let's simplify the left side
33,000 + x = 48,000
Subtract 33,000 from both sides
x = 15,000
You scored 15,000 points in the 4th game
