Each of these options can be read as "8 to 15", except for 15:8. This is read as "fifteen to eight". Lets say in 8:15 you have 8 of a and 15 of b. In 15:8, however, you have 15 of a and 8 of b. These are not the same ratio.
Question 2:
The amount of people that can go down the slide in 1 minute is 6, because 18/3 = 6. So:

The Organic Produce Stand sells bundles of tomatoes ($8) and bunches of green beans ($5). If
yesterday's total sales were $464 and people bought 3 times as many tomato bundles as green bean
bunches, how many bundles of tomatoes were sold?
Answers
Therefore, number of bundles of tomatoes which was sold as selling price are: 225.5
What is selling price or sale?
In mathematics, the term selling price can be explained with the help of profit which states, as the amount which is on the commodity and in the form of standard price called selling price. For the profit, the amount of the commodity can be designed by the shopkeeper which is bigger amount as per the cost price.
According to the question, the organic producer sells bundle of tomatoes as the selling price of $8 and the bunches of green beans as $5.
Total sales amount is: $464
In this, people bought three times more tomatoes as green bean bunches.
Let us assume tomatoes be 'x' and green beans be 'y'
3x + y = $464
x + y = $13
⇒ 2x = 451
⇒ x = 225.5 dollars
Therefore, number of bundles of tomatoes which was sold as selling price are: 225.5 dollars

Define a variable, set up an inequality, and solve. Only algebraic solutions are accepted. “Mikayla has three savings accounts that she distributes her money into each paycheck. If she wishes to put at least $80 into each account this paycheck, how much money must she make?”
Answers
Solution:
Note that Mikayla has three savings accounts that she distributes her money into each paycheck. Now, let us denote by x the money in the accounts, thus if she wishes to put at least $80 into each account this paycheck, this means that the total amount of money must be greater than or equal to 3(80). This is equivalent to say:
[tex]3(80)\leq x[/tex]this is equivalent to:
[tex]240\leq x\text{ }[/tex]so that, we can conclude that the correct answer is:

Answers
Kali will have to work a minimum of 10 hours and a maximum of 22 hours to earn between 200 and 400. The inequality representing the solution will be 9 ≤ 15.75x ≤ 22.
In the question, it is stated that Kali earns $15.75 and a flat fee 0f 50. She wants to maintain her earnings between 200 and 400. Potential earning will be 'x'. The equation representing the earnings is 200 ≤ 15.75x + 50 ≤ 400. We will have to solve the inequality and find out the value for x.
=> 200 ≤ 15.75x + 50 ≤ 400
Subtracting 50 from the equation,
=> 150 ≤ 15.75x ≤ 350
Dividing the equation by 15.75
=> 9.52 ≤ x ≤ 22.22
So, here x lies between 9.52 and 22.22. After rounding off we get range 10 and 22.
Hence, the solution for the inequality is 9.52 ≤ x ≤ 22.22

Based on the triangle inequality theorem, the set of side measurements that could be used to form a triangle is: D. 5, 11, 8.
What is the Triangle Inequality Theorem?The triangle inequality theorem states that three set of side measurements, a, b, and c would form a triangle if a + b > c, that is, the sum of any of two sides should be greater than the third side.
The set of side of measurements 5, 11, 8 will form a triangle because:
5 + 11 > 8 ⇒ 16 > 8
5 + 8 > 11 ⇒ 13 > 11
8 + 11 > 5 ⇒ 19 > 8

What is polynomial ?Polynomials are algebraic expressions with variables and coefficients. Variables are also known as indeterminates. For polynomial expressions, we can perform arithmetic operations such as addition, subtraction, multiplication, and positive integer exponents, but not division by variable.The variables and exponents of polynomials do not change when they are subtracted. Only their coefficients are subject to change. This ensures that the difference has variables and exponents that are already classified as polynomials. As a result, the difference is always a polynomial.Consider two polynomials,

The difference of polynomials is,
(9x² + 8x) - (2x²+ 3x)

What is a linear inequality and how is it solved?
Expressions with linear inequalities compare any two values using inequality symbols like "<" and ">." The mathematical expression with unequal sides is known as an inequality in mathematics. Inequality is referred to in mathematics when a relationship results in a non-equal comparison between two expressions or two numbers. Polynomial inequality, rational inequality, and absolute value inequality are the several types of inequalities that exist in mathematics.
First, create an equation for the inequality. The given equation must be solved for one or more values. Represent all of the values that you found on the number line now. On the number line, use open circles to symbolize the excluded values. the interval, then. To determine whether the values satisfy the inequality equation, substitute any random value from the interval into the inequality equation. The solutions of the given inequality equation are intervals that fulfil the inequality equation.
Given, the linear inequalities are t + 1 < -5 and t + 1 > 5
Solving the first inequality, t + 1 < -5 ⇒ t < -5 -1 ⇒ t < -6
Again, solving second inequality, t + 1 > 5 ⇒ t > 5 - 1 ⇒ t > 4
Combining the solution of both the inequalities, we have;
the value of t can take any value in (-∞, -6) U (4, ∞).
Therefore, the required value of t is (-∞, -6) U (4, ∞).

passengers and driver
If there are a total of 30 students going on the field trip, which inequality represents the number of vans, V. that will be needed?
Answers
Answer: 3 Vans are needed.
Step-by-step explanation:
There are 30 students so already you need 3 vans, if you only have 2 vans, you will be leaving behind 10 students so regardless you need a 3rd van. with 3 vans you can hold 33 people. 30 students+ 3 drivers=33 people.
The inequality that represents the number of vans for the given case is V ≤ 30/11.
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
Suppose the number of vans be V.
The number of students for each van is 11.
And, the total number of students is 30.
Now, the inequality for the number of vans can be written as,
11V ≤ 30
⇒ V ≤ 30/11
Hence, the inequality for the number of vans is given as V ≤ 30/11.

How do I solve this, and how do I know if I need to add or subtract at the beginning
Answers
Let's solve the system of equations using elimination:
4x + 5y = 14
-4x -2y = -8
First, we need to get rid of one variable.
Sometimes we multiply them by some factors to have the same number on one variable, but in this case, we can subtract the x variable
4x +5y =14
-4x-2y = -8
----------------------
4x-4x =0, 5y -2y = 3y and 14-8=6
------------------------------
0+3y = 6
Solve the equation for y
Divide by 3 into both sides
3y/3 = 6/3
y = 2
Then, replace this variable on one equation, whichever you want:
4x + 5y = 14
4x +5(2) = 14
4x +10 = 14
and solve the equation for x
4x +10 = 14
Subtract 10 on both sides
4x +10-10 = 14-10
4x = 4
Divide by 4 into both sides
4x/4 = 4/4
x = 1
You can replace both variables to confirm the results:
4x +5y =14
4(1) +5(2) = 14
4 +10 = 14
14 = 14
---------------------------------
-4x -2y = -8
-4(1) -2(2) = -8
-4-4 = -8
-8 = -8
The result is correct, so my ordered pair is (x,y) = (1,2)
