The number is 8.
Step-by-step explanation:
Finding the Number
To find the number, we have to translate the problem above to an algebraic equation. The algebraic equation refers to the statement of the equality of two algebraic expressions.
Equation:
Let "x" be the number.
4 is divided by a number - 4/x
3 divided by the number decreased by 2 - 3/x-2
"4 is divided by a number is equal to 3 divided by the number decreased by 2"
4/x = 3/x-2
Solution:
Cross multiply.
4/x = 3/x-2
x(3) = 4(x-2)
3x = 4x - 8
(Combine similar terms.)
3x - 4x = - 8
- x = - 8
- x/- 1 = - 8/- 1
x = 8
Final Answer:
8
Checking:
4/x = 3/x-2
4/8 = 3/8-2
1/2 = 3/6

solve the following system of equation using the substitution method y equals 3x - 14 y equals x - 10
Answer:
(2,-8)
Step-by-step explanation:
y have
y=3x-14
y=x-10
we can substitute y in the first equation with x-10
x-10=3x-14
solve for x
4=2x
x=2
Now that we know what x equals we can solve for y
3(2)-14

Step-by-step explanation:
Please help me . What is x equal to?
1. 2 (x+3) =10
2. 2 (x+3)=9+x
3. 2(2x+1) = 3x+8
4. 2(2x+3) =X+9
Answer:
1. x = 2
2. x = 6
3. x = 6
4. x = 1
Step-by-step explanation: i think thats it
Answer:
x = 2, x = 3, x = 6, x = 1
Step-by-step explanation:
1
2(x + 3) = 10 ( divide both sides by 2 )
x + 3 = 5 ( subtract 3 from both sides )
x = 2
2
2(x + 3) = 9 + x ← distribute parenthesis on left side
2x + 6 = 9 + x ( subtract x from both sides )
x + 6 = 9 ( subtract 6 from both sides )
x = 3
3
2(2x + 1) = 3x + 8 ← distribute parenthesis on left side
4x + 2 = 3x + 8 ( subtract 3x from both sides )
x + 2 = 8 ( subtract 2 from both sides )
x = 6
4
2(2x + 3) = x + 9 ← distribute parenthesis on left side
4x + 6 = x + 9 ( subtract x from both sides )
3x + 6 = 9 ( subtract 6 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1

What is a fraction?A fraction represents a part of a number or any number of equal parts.
A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.
We are given that;
Form=5 ^ n
Now,
To simplify the expression, we need to first rewrite the fractions with a common denominator of 60: (5/10)/(5/12)=(5×6)/(10×6)÷(5×5)/(12×5)=(30/60)/(25/60)
Then we need to invert the second fraction and multiply: (30/60)/(25/60)=(30/60)×(60/25)=30/25
Then we need to simplify the fraction by dividing both numerator and denominator by 5: 30/25=(30÷5)/(25÷5)=6/5
Finally, we need to rewrite the fraction in the form of 5n
by using the property that a/b=a×b−1
So we have: 6/5=6×5−1=50×6×5−1=50−1×6=5−1×6
Therefore, by the fraction the answer will be 5^−1×6.

Step-by-step explanation:
In a large school, it was found that 77% of students are taking a math class, 74% of student are taking an English class, and 70% of students are taking both. Find the probability that a randomly selected student is taking a math class or an English class. Write your answer as a decimal, and round to 2 decimal places if necessary. Find the probability that a randomly selected student is taking neither a math class nor an English class. Write your answer as a decimal, and round to 2 decimal places if necessary.
Answer:
0.81 = 81% probability that a randomly selected student is taking a math class or an English class.
0.19 = 19% probability that a randomly selected student is taking neither a math class nor an English class
Step-by-step explanation:
We solve this question working with the probabilities as Venn sets.
I am going to say that:
Event A: Taking a math class.
Event B: Taking an English class.
77% of students are taking a math class
This means that [tex]P(A) = 0.77[/tex]
74% of student are taking an English class
This means that [tex]P(B) = 0.74[/tex]
70% of students are taking both
This means that [tex]P(A \cap B) = 0.7[/tex]
Find the probability that a randomly selected student is taking a math class or an English class.
This is [tex]P(A \cup B)[/tex], which is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
So
[tex]P(A \cup B) = 0.77 + 0.74 - 0.7 = 0.81[/tex]
0.81 = 81% probability that a randomly selected student is taking a math class or an English class.
Find the probability that a randomly selected student is taking neither a math class nor an English class.
This is
[tex]1 - P(A \cup B) = 1 - 0.81 = 0.19[/tex]
0.19 = 19% probability that a randomly selected student is taking neither a math class nor an English class

50 points! Find the value of x. I will mark brainliest! Random answers will be reported. Thanks :)
Step-by-step explanation:
For 1st question
x = 35° + 15° {exterior angle of a triangle is equal to the sum of two opposite interior angles }
x = 50°
For second question
9x + 16° = 90° + 5x - 14°{exterior angle of a triangle is equal to the sum of two opposite interior angles }
9x - 5x = 90° - 14° - 16°
4x = 60°
x = 60° / 4
x = 15°

a takeaway sells 10 inch pizzas and 12 inch pizzas. what proportion sold were 10 inch pizzas in week 1. What proportion sold were 10 inch in week 2
Answer:
In week 1, 69.15% of sales were 10-inch pizzas, and the remaining 30.85% were 12-inch pizzas; while in week 2, 71.09% of sales were 10-inch pizzas, and the remaining 28.91% were 12-inch pizzas.
Step-by-step explanation:
Given that a takeaway sells 10 inch pizzas and 12 inch pizzas, to determine what proportion sold were 10 inch pizzas in week 1 and what proportion sold were 10 inch in week 2, the following calculation must be performed:
Week 1 = 736 total sales
10-inch pizzas = 509
736 = 100
509 = X
509 x 100/736 = X
50,900 / 736 = X
69.15 = X
100 - 69.15 = 30.85
Thus, in week 1, 69.15% of sales were 10-inch pizzas, while the remaining 30.85% were 12-inch pizzas.
Week 2 = 1076 total sales
10-inch pizzas = 765
1076 = 100
765 = x
765 x 100/1076 = X
76500/1076 = X
71.09 = X
100 - 71.09 = 28.91
Thus, in week 2, 71.09% of sales were 10-inch pizzas, while the remaining 28.91% were 12-inch pizzas.
