Answer:
x = 8
Step-by-step explanation:
By Basic Proportionality Theorem:
[tex] \frac{3}{x - 2} = \frac{x}{x + 8} \\ \\ x(x - 2) = 3(x + 8) \\ \\ {x}^{2} - 2x = 3x + 24 \\ \\ {x}^{2} - 2x - 3x - 24 = 0 \\ \\ {x}^{2} - 5x - 24 = 0 \\ \\ {x}^{2} - 8x + 3x - 24 = 0 \\ \\ x (x - 8) + 3(x - 8) = 0 \\ \\ (x - 8)(x + 3) = 0 \\ \\ x - 8 = 0 \: \: or \: \: x + 3 = 0 \\ \\ x = 8 \: \: or \: \: x = - 3 \\ \\ \because \: length \: can \: not \: be \: - ve \\ \\ \implies \: x \neq - 3 \\ \\ \implies \: x = 8[/tex]

The cost of renting a bowling alley for a party is $110, plus $5 a person for food. Which equation can be used to find the total cost, C, of a party at a bowling alley for x friends?
Answer:
c=110+5x
Step-by-step explanation:
The equation that represents the total cost is C = 5x + 110.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expense of leasing a bowling alley for a party is $110, in addition to $5 an individual for food.
Let 'C' be the total cost and 'x' be the number of friends. Then the equation is written as,
C = 5x + 110
The equation that represents the total cost is C = 5x + 110.

The tree is 10 yards tall and the base of the tree is 5 yards away from the edge of a park bench. She calculated that her oak tree model should be 0.4 yards tall. What is the distance, in yards, from the base of the model tree to the edge of the model bench?
Answer:
It's 0.20

y=x+2
y=-3x
Answer:
Your answer is: (-1/2, 3/2)
Step-by-step explanation:
y = x + 2
y = -3x
Use substitution by plugging the second equation into the first.
-3x = x +2
Subtract x from both sides to combine the variables.
-4x = 2
Divide both sides by -4 to isolate the variable x.
x = 2/-4
Simplify.
x = -1/2
Plug x into one of the equations to find y.
y = (-1/2) + 2
y = 3/2
Plug x into the other equation to confirm your answer.
y = -3(-1/2)
y = 3/2
Your answer is: (-1/2, 3/2)

Step-by-step explanation:
Answer:
The answer is D. $4,900
Step-by-step explanation:

s = a / 0.04 = 196 / 0.04 = $4900 = Ann's sales
so the answer for Ann's sales is $4,900
What is this number in standard form?
(5×1,000)+(7×10)+(8×1)+(4×110)+(1×11,000)
Standard form of given expanded form of a number is 16518.
What is meant by expanded form?The expanded form of the number is the splitting of numbers based on the place value, such as ones, tens, hundreds, thousands, ten thousand, and so on. The number that is represented by the sum of each digit multiplied by its place value is called the expanded form of the number.
Given
Expanded form = (5×1,000)+(7×10)+(8×1)+(4×110)+(1×11,000)
We have to convert the expanded form into standard form
= 5000 + 70 + 8 + 440 + 11000
= 16518
Thus, standard form of given number is 16518.

Answer:
16,518
(or 1.6518 x 10⁴)
Step-by-step explanation:
Expanded form: The digits of a number are split into individual digits based on their place value. Each digit of a number can be written in multiple of 1, 10, 100, 1000, etc.
Standard form: The combination of digits written together as a single number.
The given number is not quite, but almost, written in expanded form:
(5 × 1,000) + (7 × 10) + (8 × 1) + (4 × 110) + (1 × 11,000)
For it to truly be written in expanded form, the (4 × 110) would be written as (4 × 10) + (4 × 100) and the (1 × 11,000) would be written as either (11 × 1,000) or (1 × 10,000) + (1 × 1,000).
If the number should be written in standard form as defined above, carry out the operations in the parentheses, then add them together:
[tex]\large\begin{array}{l c r}8 \times 1 & = & 8\\7 \times 10 & = & 70\\4 \times 110 & = & 440\\5 \times 1000 & = & 5000\\1 \times 11000 & = & 11000\\\cline{3-3}& & 16518\end{array}[/tex]
-----------------------------------------------------------------------------------------------------
However, in math there is another type of Standard Form (also called "Scientific notation") that is written in the form of [tex]a \times 10^n[/tex], where [tex]1\leq a < 10[/tex] and [tex]n[/tex] is any positive or negative whole number.
To convert a number into standard form, move the decimal point to the left or right until there is one digit to the left of the decimal point.
The number of times you have moved the decimal point is the power of 10 ([tex]n[/tex]).
If the decimal point has moved to the left, the power is positive.
If the decimal point has moved to the right, the power is negative.
To convert 16518 into standard form:
Move the decimal point 4 places to the left and multiply by 10 to the power of the number of places the decimal was moved (4):
⇒ 1.6518 x 10⁴

At the mall in Miami, Roberto found a jacket he liked. The normal price was $120, but the jacket was on sale for 40% off. If Roberto has $50 to spend, does he have enough to buy the jacket? If not, how much more money does he need?
Answer: No, He will need $22 to add to his money to buy jacket.
Step-by-step explanation:
Normal price of jacket =$120,
New price = 40% off which means 40% Less than the Normal price
= 40/ 100 x 120
=0.4 x 120 = 48; 120 -48= $72
New Price = $72
Therefore Roberto with $50 to spend does not have enough to buy the jacket
He will need $72- $50 =$22 to add to his money to buy jacket.

1. Write an equation showing the relationship between 3 and y.
Type the equation in the box below.
I
Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30
Answer: 3x + 2y = 30
Step-by-step explanation:
A = L x W
The sum of the rectangle is 30.
One angle is 3 and x, the other one is 2 and y.
Multiply 3 with x = 3x.
Multiply 2 with y = 2y
Then create your equation plugging in 30 as the answer to 3x + 2y
