Answer:
a. 12
b. it depends on the color of the marble.
Step-by-step explanation:
In this case the number of ways would be the number of events, in this case the events would be the total number of marbles since any of them can come out. so:
4 + 3 + 3 + 2 = 12
Therefore, the number of ways the event can occur is 12 ways.
Now, in the favorable outcomes of the event, it would come depending on what color the marble would be, whether it be red, blue, yellow or green.
In each color, the number of the favorable outcomes of the event would be the quantity of each marble, that is, 4 for red, 3 for blue, 3 for yellow and 2 for green.

2x+x+3=6x
What does x equal?
Answer: x=1
Step-by-step explanation:
Simplify 2x+x+3 to 3x+3
3x+3=6x
Subtract 3x from both sides.
3=6x-3x
Simplify 6x-3x to 3x
3=3x
Divide both sides by 3.
1=x
Switch both sides
x=1
Answer:
[tex]2 x + x + 3 = 6x : x = 1[/tex]
Step-by-step explanation:
[tex]2x + x + 3 = 6x[/tex]
Add similar elements: [tex]2x + x = 3x[/tex]
[tex]3x + 3 = 6x[/tex]
Subtract 3 from both sides:
[tex]3x + 3 - 3 = 6x - 3[/tex]
Simplify:
[tex]3x = 6x - 3[/tex]
Subtract 6x from both sides:
[tex]3x - 6x = 6x -3 - 6x[/tex]
Simplify:
[tex]-3x = - 3[/tex]
Divide both sides by -3:
[tex]\frac{-3x}{-3} = \frac{-3}{-3}[/tex]
Simplify:
[tex]x = 1[/tex]

Suppose you deposit $100 in Account A with a simple interest rate of 3.4%, and $300 in Account B with a simple interest rate of 1.8%. One year later, you get a bank statement, that shows the interest for Account A is $3.40 and the interest for Account B is $540.00. Which account is incorrect?
Answer:Statement for Account B is incorrect.
Step-by-step explanation:
Interest for Account B should be 300 x 1.8% = $5.40
The account B is incorrect. The interest of account B is $5.40.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The property used is the Associative Property of Addition, which allows us to regroup the terms without changing their order.
We grouped the terms (7n + 3n) and (15 - 8) together as (7 + 3)n and simplified them to get 10n + 7.
The property used is the Distributive Property of Multiplication over Addition, which allows us to distribute a factor to each term inside a parenthesis.
We distributed 2 to (4n + 2) to get 8n + 4, and then combined like terms to get,
12n + 8n + 4 = 20n + 4.
The property used is the Addition Property of Equality, which allows us to add the same quantity to both sides of an equation without changing its value.
We added 9 to both sides of the equation to get 15n + (17n + 9) + 9 = 15n + 17n + 18, which simplifies to 22n + 9.
The property used is the Associative Property of Addition, which allows us to regroup the terms without changing their order.
We grouped the terms (12n + 7n) and (6) together as (12 + 7)n and (6), and simplified to get 19n + 6.
Therefore,
15 + 7n - 8 + 3n = 7n + 3n + 15 - 8 = (7 + 3)n + 15 - 8 = 10 n + 7
Associative Property of Addition
12n + 2 (4 n + 2) = 12 n + 8 n + 4 = (12 + 8) n + 9 = 20 n + 9

Answer: 5(h + w)
Step-by-step explanation:
Number of visitors = 5
Each of the five visitors purchased:
One hamburger (h) + one bottle water (w)
Expression for the amount of harmburger and bottle water purchased is thus ;
Number of visitors × (number of harmburger per person + Number of bottle water per person)
5 ( 1h + 1w)
5h + 5w = 5(h + w)
Question 1
A landscape architect is designing a pool that has this top view:
a. How much water will be needed to fill this pool 4 feet deep?
b. Before filling up the pool, it gets lined with a plastic liner. How much liner is needed for this pool?
Answer:
Water needed for pool = 486 cubic feet
Plastic liner required for the pool = 298.3 feet
Step-by-step explanation:
Top view of the pool is a composite figure, having one rectangle and a trapezoid.
1). Water needed for the pool = volume of the pool
Volume of the pool = Area of the base × Depth
= (Area of the rectangle + Area of the trapezoid)× depth
Area of the trapezoid = [tex]\frac{1}{2}(b_{1}+b_{2})\times h[/tex]
= [tex]\frac{1}{2}(11+9)\times (12-1.5)[/tex]
= 105 ft²
Area of the rectangle = Length × width
= 11 × 1.5
= 16.5 ft²
Now, volume of the pool = (105 + 16.5) × 4
= 121.5 × 4
= 486 cubic feet
b). Liner required = surface area of the pool excluding top
= Surface area of the walls + Area of the pool base
= (Perimeter of the pool) × depth + area of the base
= (12 + 11 + 1.5 + 10.7 + 9)×4 + 121.5
= 176.8 + 121.5
= 298.3 square feet
Therefore, amount of water required = 486 cubic feet
liner needed = 298.3 square feet
a. Water needed for pool = 486 cubic feet.
b. Plastic liner required for the pool = 298.3 feet.
Calculation of water needed and plastic liner required:a.
Water needed for the pool = volume of the pool
Here
Volume of the pool = Area of the base × Depth
= (Area of the rectangle + Area of the trapezoid)× depth
So,
Area of the trapezoid = 0.5 × (b1 + b2) × h
= 0.5 × (11 + 9 )(12 -1.5)
= 105 ft²
Now the area of the rectangle
= Length × width
= 11 × 1.5
= 16.5 ft²
Now, volume of the pool = (105 + 16.5) × 4
= 121.5 × 4
= 486 cubic feet
b). Liner required = surface area of the pool excluding top
= Surface area of the walls + Area of the pool base
= (Perimeter of the pool) × depth + area of the base
= (12 + 11 + 1.5 + 10.7 + 9)×4 + 121.5
= 176.8 + 121.5
= 298.3 square feet

(a) what is the gcf of each term of the expression? (b) write the factored form of the expression for the height of the rocket after T seconds. (c) well the height of the rocket be greater after four seconds or after six seconds?
Answer:
Step-by-step explanation:
Given
Height of the rocket is given by
[tex]h=128t-16t^2[/tex]
[tex]h=8\times 16t-16t\times t[/tex]
(a)Greatest common factor in each term is [tex]16t[/tex]
(b)
[tex]h=8\times 16t-16t\times t[/tex]
[tex]h=16t(8-t)[/tex]
(c)
After [tex]t=4\ s[/tex]
[tex]h=16\times 4(8-4)[/tex]
[tex]h=256\ m[/tex]

-8x -3(2x+1)=67 Find the value of X
Answer:
x=-5
Step-by-step explanation:
-8x-6x-3=67
-14x=70
x=-5
Answer:
x = -5
Step-by-step explanation:
Solve for x:
-8 x - 3 (2 x + 1) = 67
-3 (2 x + 1) = -6 x - 3:
-6 x - 3 - 8 x = 67
Grouping like terms, -6 x - 8 x - 3 = (-8 x - 6 x) - 3:
(-8 x - 6 x) - 3 = 67
-8 x - 6 x = -14 x:
-14 x - 3 = 67
Add 3 to both sides:
(3 - 3) - 14 x = 3 + 67
3 - 3 = 0:
-14 x = 67 + 3
67 + 3 = 70:
-14 x = 70
Divide both sides of -14 x = 70 by -14:
(-14 x)/(-14) = 70/(-14)
(-14)/(-14) = 1:
x = 70/(-14)
The gcd of 70 and -14 is 14, so 70/(-14) = (14×5)/(14 (-1)) = 14/14×5/(-1) = 5/(-1):
x = 5/(-1)
Multiply numerator and denominator of 5/(-1) by -1:
Answer: x = -5
