One month lashonda rented 7 movies and 9 video games for a total of $73 the next month she rented 5 movies and 3 video games for a total of $29 find the rental cost for each movie and each video game
Answer:
Solve a system of equations with two unknowns x and y
where x is the rental price for the movie and y is the rent for video games
7x + 9y = 73
5x + 3y = 29
Solving the result: x = $ 1.75, y = $ 6.75
Step-by-step explanation:
A number,y,is 2 more than 3 times another number,x, the sum of the 2 numbers is 26. What are the two numbers?
-2x + 3 – 5x – 4 = -3x – 8 + 10x
what is x
Answer:
x= 1/2
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+3−5x−4=−3x−8+10x
Step 1: Simplify both sides of the equation.
−2x+3−5x−4=−3x−8+10x
−2x+3+−5x+−4=−3x+−8+10x
(−2x+−5x)+(3+−4)=(−3x+10x)+(−8)(Combine Like Terms)
−7x+−1=7x+−8
−7x−1=7x−8
Step 2: Subtract 7x from both sides.
−7x−1−7x=7x−8−7x
−14x−1=−8
Step 3: Add 1 to both sides.
−14x−1+1=−8+1
−14x=−7
Step 4: Divide both sides by -14.

O Right 3 Up 4
Left 3. Up 4
Down 3. Right 4
O Up 3 Right 4
Answer:
3 down, 4 up
Step-by-step explanation:
-3 is the X line, which starts on 0, if you subtract 3, or add -3, you would have to go down, 3 down. 4 is on the Y line, so you add, go left to add on the Y line, 4 up.
Always start with you X coordinate. Here is a tip to help you (X, Y)
I NEED HELP! how do i find the initial value?!
Answer:
i think it is 2, please forgive me if im wrong
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
you need to find a pattern to write an equation first and the constant term ( aka as y-intercept , where the graph touches the y-axis) is the initial value
we se that each y= x+5 ( 7=2+5, 9=4+5, ...) so the initial value was 5
if x wold be 1 then y is 5

The difference of 8 and six times a number is a minimum of sixty-eight
Answer:
Let's represent the unknown number with the variable, x.
The word "difference" indicates subtraction and "times" indicates multiplication.
The "difference of 8 and six times a number" would be represented as: 8 - 6x
NOTE: The order of the terms is important (8- 6x is not the same as 6x - 8).
This expression 8 - 6x must be at least 68 to meet the requirement of being at least a "minimum".
The final inequality will be: 8 - 6x ≥ 68
Step-by-step explanation:
hope this helps :)
Answer:
6x-8>=68

18 increased by twice a number
Answer:
18+2x
Step-by-step explanation:
Let the number be x.
Translate: 2x + 18 = x - 4.
Subtract x from each side: x + 18 = -4.
Subtract 18: x = -22.
Check: 2(-22) + 18 = -44 + 18 = -26; -22 - 4 = -26.
8 increased by twice a number = 18+2x
What is a linear equation?A linear equation has one or two variables.
No variable in a linear equation is raised to a power greater than 1.No variable is used as the denominator of a fraction. A linear equation is defined as an equation that is written in the form of ax+by=c. When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.solving this we will get the valve of Y if x is given.

Mark said he can decompose five six into three fractions with three different numerators and the same denominator is this possible explain
Answer:
1/6 ; 2/6 ; 2/6
Step-by-step explanation:
To split 5/6 into. 3 different fractions with the same denominator and different numerator values;
The integer value of the numerator 5 can be divided into 3 different whole Number values ;
It could be :
5 = 3 + 1 + 1
5 = 2 + 2 + 1
Hence, we could have ;
3/6 +. 1/6 + 1/6
Or
2/6 + 2/6 + 1/3

change 4x - 5y = 10 into slope intercept form and graph
Answer:
Slope intercept form: y = 4/5x - 2
Step-by-step explanation:
(subtract 4x from both sides) -5y = -4x + 10
(divide everything by -5) y = 4/5x - 2
To graph, place a point at (0,-2), and then travel up 4 and over right 5 (or down 4 and to the left 5) to place the next point, then draw a line through the points
The social studies teacher wants to know whether the students in the entire school prefer a model United Nations activity or a student government activity. The teacher draws a random sample from the following groups: All teachers in the school All boys in each grade All students in each grade All students in the social studies club Which group best represents the population he should take a random sample from to get the best results for his survey?
All teachers in the school
All boys in each grade
All students in each grade
All students in the social studies club
Answer:
all students each grade, its a better representation of the wants of the whole group being affected
Step-by-step explanation:
Answer:
C: All students in each grade
Step-by-step explanation:
It cant be all teachers in the school since at the beginning of the question it says "whether the students" not whether the teachers plus it is not a mxed variety, so this question was sort of trying to catch you off guard
The reason why is if you pick all the boys in each grade then it wouldnt really be random since your picking the gender you want to answer it has to be a mixed variety all ages all genders and so on
Yes! All students in each grade would be a mixed variety since its all ages, all genders, and all grades this answer was a little obvious since they sort of gave you the answer saying "The social studies teacher wants to know whether the students in the entire school"
All students in the social studies club wouldnt be a good answer either since (as i said before) it has to be random and your picking who you want to answer plus since there in the club with the social studie steacher they are more likely to pick what she wants to pick
So the answer would be C: All students in each grade

Lauren says that -3.5 is greater than -3 1/3. Do you agree? Explain.
Answer:
[tex]-3\frac{1}{2}<-3\frac{1}{3}[/tex]
Step-by-step explanation:
-3.5 means -(3 + [tex]\frac{1}{2}[/tex])
In other words, -3.5 = [tex]-3\frac{1}{2}[/tex]
When we draw two numbers [tex]-3\frac{1}{3}[/tex] and [tex]-3\frac{1}{2}[/tex] on a number line, [tex]-3\frac{1}{2}[/tex] comes first from left to right.
We know that all the numbers on a number line from left to right are in increasing order.
Therefore, [tex]-3\frac{1}{2}[/tex] is smaller than [tex]-3\frac{1}{3}[/tex].
[tex]-3\frac{1}{2}<-3\frac{1}{3}[/tex]
Lauren is not correct.
The mean weight of a group of dogs in a dog show is 38 pounds. If a certain dog in the show
has a z-score of 0, how much does it weigh?
Answer:
The weight of dogs x = 38pounds
Step-by-step explanation:
Step(i):-
Given that the mean weight of a group of dogs
μ = 38 pounds
Let 'x' be the weight of dogs
Let 'x' be the random variable in normal distribution
Given that z-score is zero
Step(ii):-
we know that the z-score
[tex]Z = \frac{x-mean}{S.D}[/tex]
⇒ [tex]0 = \frac{x-38}{S.D}[/tex]
⇒ 0 = x-38
⇒ x-38 = 0
⇒ x =38
Final answer:-
The weight of dogs x = 38pounds
