What is the solution of -17 = -2y + 13 – 8y?
Answer:
3
Step-by-step explanation:
-17 = -2y + 13 - 8y
-17 = -10y + 13
-30 = -10y
3 = y
y = 3
Answer:
y = 3
Step-by-step explanation:
- 17 = - 2y + 13 - 8y
- 10y + 13 = - 17
- 10y + 13 - 13 = - 17 - 13
- 10y = - 30
- 10y ÷ - 10 = - 30 ÷ - 10
y = 3

Alan has 3 quarters and 7 dimes in his pocket. If he takes out a coin, puts it back in his pocket, and then takes out a coin again, what is the probability that both coins are dimes?
Answer:
Probability of picking a dime both times = (7/10)^2 = 49/100, or 0.49
Step-by-step explanation:
Picking with replacement, twice from 3 quarters and 7 dimes.
Probability of picking a dime each time = 7/10.
Probability of picking a dime both times = (7/10)^2 = 49/100, or 0.49

Which best describes the domain and range of the function y = = 4x²?
Answer:
Domain: (-infinity, infinity)
Range: [0, infinity)
Step-by-step explanation:
y = 4x^2 is a quadratic function whose parabolic graph goes through (0, 0) and opens upward. (0, 0) is both the vertex and the minimum of this function and graph. Here x can take on any value, but y is limited to [0, infinity).

Which triangle’s unknown side length measures 7 units?
Answer:4
Step-by-step explanation:
The girls in Lana’s troop set a goal to sell 1,000 boxes of cookies this year. There are 13 girls in the troop. At least how many boxes of cookies should each girl sell to reach their goal?
Answer:
77 boxes
Step-by-step explanation:
Step 1:
Lana's troop must sell 1000 boxes of cookies, but there are 13 girls in total. Supposing that each girl will sell an equal amount of boxes, we can simply divide:
[tex]1000[/tex]÷[tex]13\approx76.92[/tex] boxes.
Step 2:
However, it would seem unlikely that the girls would decide to sell fractions of a box of cookies. We should round...up or down?
If we round down, each girl will sell 76 boxes of cookies. Hmm... then they would'nt be able to sell a total of 1000 boxes of cookies! We need to round up.
Therefore, each girl should sell at least [tex]\fbox{77}[/tex] boxes.

Find the value of x . Write your answer in simplest form.
Answer:
7√2
Step-by-step explanation:
From the diagram given;
Hypotenuse = x
Opposite = 7
Angle = 45 degrees
According to SOH CAH TOA identity
Sin theta = opposite/hypotenuse
Sin 45 = 7/x
x = 7/sin45
x = 7/1/√2
x = 7 * √2/1
x = 7√2
Hence the value of x is 7√2

Answer:
7x^2*(x-4)*(x+6)
Step-by-step explanation:
7x^4 + 14x^3 - 168x^2
common factor 7x^2
7x^2*( x^2+2x-24)
now we factor ( x^2+2x-24)
(x-4)*(x+6)
Solution
7x^2*(x-4(*(x+6)
The factorized form 7x²(x-4)(x+6) of the polynomial 7x⁴ + 14x³ - 168x².
What is polynomial ?
The polynomial is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
Given polynomial as:
7x⁴ + 14x³ - 168x²
There is a common factor 7x²
7x²( x² + 2x - 24)
To determine the factor of ( x² + 2x - 24)
⇒ 7x²( x² + 2x - 24)
⇒ 7x²( x² + 6x - 4x -24)
⇒ 7x²[x(x+6) - 4(x+6)]
⇒ 7x²(x-4)(x+6)
Hence, the factorized form 7x²(x-4)(x+6) of the polynomial 7x⁴ + 14x³ - 168x².

Jin sells concert tickets at the theater box office. The ratio of student tickets to adult tickets sold is 4 : 5. Each student ticket costs $5, and each adult ticket costs $7. Jin sells 189 tickets altogether. Part A: How many student tickets does Jin sell? How many adult tickets? Explain your reasoning. Part B: How much more money does Jin receive from selling adult tickets than from selling student tickets? Explain your reasoning
Answer:
Part A: 84, 105
Part B: $315
Step-by-step explanation:
Part A:
4 student tickets + 5 adult ticekts = 9 tickets
The ratio of student tickets to adult tickets to total tickets is
4 : 5 : 9
He sold x times more tickets than the numbers on the ratio.
He sold 9x tickets.
9x = 189
x = 21
Student tickets:
4x = 4(21) = 84
He sold 84 student tickets.
Adult tickets:
5x = 5(21) = 105
He sold 105 adult tickets.
Part B:
Student tickets:
He sold 84 student tickets at $5 each.
The amount of money from the sale of student tickets is:
84 * $5 = $420
Adult tickets:
He sold 105 adult tickets at $7 each.
The amount of money from the sale of adult tickets is:
105 * $7 = $735
Difference:
$735 - $420 = $315
84 student tickets, 105 adult tickets were sold by Jin and $315 more money does Jin receive from selling adult tickets than from selling student tickets
What is Equation?Two or more expressions with an Equal sign is called as Equation
The ratio of student tickets to adult tickets sold is 4 : 5
4 student tickets + 5 adult ticekts = 189
4x+5x=189
9x = 189
Divide both sides by 9
x = 21
The number of Student tickets:
4x = 4(21) = 84
Jin sold 84 student tickets.
Adult tickets:
5x = 5(21) = 105
Jin sold 105 adult tickets.
Part B:
He sold 84 student tickets at $5 each.
The amount of money from the sale of student tickets is:
84 * $5 = $420
Adult tickets:
He sold 105 adult tickets at $7 each.
The amount of money from the sale of adult tickets is:
105 * $7 = $735
Difference:
$735 - $420 = $315
Hence 84 student tickets, 105 adult tickets were sold by Jin and $315 more money does Jin receive from selling adult tickets than from selling student tickets

A circular flower bed is 19m in diameter and has a circular sidewalk around it that is 3m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi.
The area of the sidewalk ____ m².
Area of the circular sidewalk around flowerbed is 207.24 m² .
What is area?Area is the amount of space occupied by a two-dimensional shape. That is, it is a quantity that measures the number of unit squares that cover the surface of a closed figure. Standard area unit is square unit.
Given,
Diameter of flowerbed = 19m
radius = diameter/2 = 19/2 = 9.5 m
Area of flower bed A
= πr²
= 3.14(9.5)²
= 3.14(90.25)
= 283.385 m²
width of the sidewalk = 3m
radius of flower bed with sidewalk = 9.5 + 3 = 12.5m
Area of flower bed with sidewalk A'
= 3.14(12.5)²
= 3.14(156.25)
= 490.625 m²
Area of the sidewalk
= A' - A
= 490.625 - 283.385
= 207.24 m²
Hence, 207.24 m² is area of the circular sidewalk around flowerbed.
