Answer:
Identify the variable as the number of runs. Identify the inequality symbol needed as greater than. Identify the constant as 5 runs. Write the inequality as r > 5.
Step-by-step explanation:
The inequality that represents the situation "The winning baseball team scored more than 5 runs" is (r > 5) where r represents the total runs scored by the team and this can be determined by using the given data.
Given :
The winning baseball team scored more than 5 runs.
The following steps can be used to determine the inequality that represents the given situation:
Step 1 - Let the total runs scored by the baseball team be 'r'.
Step 2 - Now, it is given that the winning baseball team scored more than 5 runs, the inequality that represents this situation is:

Robbie, Jennie, Willie, and Kylie played a numbers game. Jennie picked a number but did not tell her friends. Robbie and Willie both picked a number as well, and Jennie described their numbers like this to Kylie.
Robbie picked a number that is nine more than four times Jennie's number.
Willie picked a number that is two less than three times Robbie's number.
Deciding to call her number, n, Jennie asked Kylie to write an expression that describes Willie's number.
Kylie came up with two expressions that equal Willie's number.
What are the equations?
Answer:
1. 3(4n+9)-2
2. 3*13n-2
Step-by-step explanation:(*)This symbol that looks like a little star means multiplication.
The two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34
What is Expression?An expression is combination of variables, numbers and operators.
Robbie's number = 4J + 9, where J is Jennie's number.
Now we can use this expression to find Willie's number:
Willie's number = 3(4J + 9) - 2 = 12J + 25
So one equation that describes Willie's number is:
W = 12J + 25
Kylie found another expression that equals Willie's number, so we can find it by solving for J in Robbie's expression and substituting it into Willie's expression:
Robbie's number = 4J + 9
4J = Robbie's number - 9
J = (Robbie's number - 9)/4
Substitute this expression for J into Willie's expression:
W = 12J + 25
W = 12[(Robbie's number - 9)/4] + 25
W = 3(Robbie's number - 9) + 25
W = 3(4J + 9 - 9) + 25 (substituting 4J + 9 for Robbie's number)
W = 12J + 34
So another equation that describes Willie's number is:
W = 12J + 34
Therefore, the two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34

A pitcher needs more than one pitch to be effective. Dizzy uses his changeup only half as much as his fastball, and to save his arm, he throws a slider a third as much as his fastball. In a 110-pitch game, how many sliders would he throw?
In Dizzy's 110-pitch game, he threw 20 sliders. The answer was found by setting up and solving algebraic equations based on the information given in the question.
Explanation:This question is about using algebra to solve word problems. Let's denote the number of fastballs Dizzy throws as F, the number of changeups as C, and the number of sliders as S.
According to the question, Dizzy throws his changeup half as much as his fastball (C = 0.5F) and his slider a third as much as his fastball (S = F/3). We also know the total number of pitches (110) is the sum of F, C, and S pitches (110 = F + C + S).
We then substitute the expressions for C and S from our first two equations into our third equation to get: 110 = F + 0.5F + F/3. Solving this equation gives us F = 60. We substitute F = 60 into S = F/3 to find that Dizzy threw 20 sliders in the game.

Step-by-step explanation:
A cleaning company charges x dollars per hour to clean floors and y dollars per hour to clean the rest of a house.
-When the company spends 2 hours to clean floors and 3 hours to clean the rest of a house, the total charge is $84.
-When the company spends 1 hour to clean floors and 4 hours to clean the rest of a house, the total charge is $87.
Which ordered pair represents the hourly charges to clean floors and to clean the rest of the house?
A. (12, 20)
B. (15, 18)
C. (18, 15)
D. (20, 12)
Note: Please show work. My teacher checks it.
The hourly charges to clean floors and to clean the rest of the house are $15 and $18, respectively. We determine this by setting up a system of equations from the provided scenarios and solving for x and y.
To solve for the hourly charges to clean floors (x) and to clean the rest of the house (y), we need to set up two equations based on the information provided:
2x + 3y = 84 (from the first scenario)1x + 4y = 87 (from the second scenario)Let's solve this system of equations step by step.
Step 1: From the second equation, we can express x in terms of y:
x = 87 - 4y
Step 2: Substitute this expression for x in the first equation:
2(87 - 4y) + 3y = 84
Which simplifies to:
174 - 8y + 3y = 84
Combining like terms gives us:
-5y = -90
Step 3: Solve for y:
y = 18
Step 4: Now, plug the value of y back into the expression for x:
x = 87 - 4(18)
x = 15
Therefore, the hourly charges to clean floors and to clean the rest of the house are $15 and $18 respectively, which corresponds to option B. (15, 18).

Quadrilateral KLMN is a rectangle. The coordinates of L are L(1,-4), and the coordinates of Mare M(3,-2). Find the slopes of sides KL, LM, MN, and NK.
Answer: its A
Step-by-step explanation:
Side AB is parallel to side DC so the alternate interior angles, angle ABD and angle BDC, are congruent. Side AB is equal to side DC and DB is the side common to triangles ABD and BCD. Therefore, the triangles ABD and CDB are congruent by _______________. By CPCTC, angles DBC and ADB are congruent and sides AD and BC are congruent. Angle DBC and angle ADB form a pair of alternate interior angles. Therefore, AD is congruent and parallel to BC. Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel. Which phrase best completes the student's proof?
Final answer:
The triangles ABD and CDB are congruent by the Side-Angle-Side (SAS) postulate, leading to the conclusion that quadrilateral ABCD is a parallelogram.
Explanation:
The triangles ABD and CDB can be proved congruent by the Side-Angle-Side (SAS) postulate. Since side AB is parallel to side DC, the alternate interior angles angle ABD and angle BDC are congruent. With both triangles sharing side DB and having equal sides AB and DC, the two triangles satisfy the conditions of the SAS postulate.
By the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) principle, angles DBC and ADB are congruent as well as sides AD and BC. Since angle DBC and angle ADB form a pair of alternate interior angles, this implies that AD is congruent and parallel to BC. This leads to the conclusion that quadrilateral ABCD is a parallelogram, characterized by its opposite sides being equal and parallel.
