Answer:
$8.75
Step-by-step explanation:
Lets put the number of dog bowls as "x" and the number of bones as "y" When we write the equation it comes out like this:
3x+4y=$11.50
2x+8y=$13
Make the "x" equal on both side so we find the lcm of 3 and 2 which 6 so we multiply 2 on the top and 3 on the bottom which changes the equation to
6x+8y=$23
6x+24y=$39 Then we subtract which equals
-16y=-$-13
y=13/16 or 0.8125 we put the "y" on the equation which makes
3x+3.25=11.50 To solve the question: 4(13/16) + 2(2.75)=$8.75 3x=8.25: x= 2.75
Final answer:
Andrew will pay $12 for 4 dog bowls and 2 bones, after calculating the individual prices of the items by setting up and solving a system of equations based on Rhonda's and Kelly's purchases.
Explanation:
To determine how much Andrew will pay for 4 dog bowls and 2 bones, we need to establish the price of a single dog bowl and a single bone. We can do this by setting up two equations based on the transactions made by Rhonda and Kelly.
Let B be the price of one dog bowl and O the price of one bone. Therefore, Rhonda's purchase gives us the equation 3B + 4O = $11.50. Kelly's purchase gives us the equation 2B + 8O = $13.
We can solve this system of equations either by substitution or by the elimination method. In this case, elimination may be more straightforward:
Multiply the first equation by 2, which gives us 6B + 8O = $23.We now subtract Kelly's equation from this, resulting in (6B + 8O) - (2B + 8O) = $23 - $13, simplifying to 4B = $10.Now we know that one dog bowl costs B = $2.50.To find the cost of one bone, we substitute B = $2.50 into either of the original equations. Using Rhonda's equation: 3($2.50) + 4O = $11.50, which simplifies to $7.50 + 4O = $11.50, and further to 4O = $4, meaning O = $1.00.With the prices determined, Andrew's total cost for 4 dog bowls and 2 bones will be 4B + 2O, which equates to 4($2.50) + 2($1.00).Calculating this gives us $10 + $2, which is a total of $12 that Andrew will pay.What integers are plotted on the number line below?
Hey there!
We can see on this number line that each tick mark represents one because every five marks, there is a difference of five.
Two marks to the left of 0 will be 0 minus 2, so -2.
Three marks to the left of -5 will be -5 minus 3, so -8.
Your answer is -8 and -2.
Hope this helps!
Final answer:
The integers that are being referred to are -8 and -2, which are negative whole numbers located on the left side of zero on a number line.
Explanation:
When plotted on the number line, integers represent whole numbers that can be positive, negative, or zero.
To identify the integers that are plotted, one would look for distinct marks or points on the number line that correspond to whole numbers.
Based on the data, we come to the conclusion that the numbers in question are -8 and -2.
The integers plotted on the number line are -8 and -2. The integer -8 is to the left of -2 on the number line.
These two numbers are examples of negative integers, which are located to the left of zero on a standard number line. The understanding of how to read a number line and identify the placement of integers is a key concept in mathematics, which allows for better comprehension of more complex mathematical ideas such as rational numbers, real numbers, and complex numbers.

y = 4x + 11
y = -2x - 1
Answer:
x = -2, y= 3
Step-by-step explanation:
y = 4x + 11
y = -2x - 1
Because both equations are equal to y, we can set them equal to each other
4x + 11 = -2x - 1
Add 2x to each side
4x+2x +11 = -2x+2x -1
6x +11 = -1
Subtract 11 from each side
6x+11-11=-1-11
6x = -12
Divide each side by 6
6x/6 = -12/6
x = -2
Now we need to find y
y = -2x-1
y = -2(-2)-1
=4-1

Answer:
x=-17 and x=-19
Step-by-step explanation:
-17+18=1
-19+18=-1
|-1| =1
Answer:
-17 and -19
Step-by-step explanation:
Absolute value equations have two problems and two solutions unless the original answer equals a negative-then it would be no solution.
x + 18 =1 subtract 18 from both sides to get x by itself
x = 1-18
x= -17
x +18 = -1 subtract 18 from both sides to get x by itself
x= -1 -18
x= -19

What is the distance between the points (4,-2) and (-1,10)?
A. 5 units
B. 6 units
C. 12 units
D. 13 units
Answer:
D. 13 units
Step-by-step explanation:
The distance between the points (4,-2) and (-1,10) is 13 units.
Explanation:To find the distance between two points, we can use the distance formula. The distance formula is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this case, the coordinates of the first point are (4, -2) and the coordinates of the second point are (-1, 10). Plugging these values into the distance formula, we get:
d = sqrt((-1 - 4)^2 + (10 - (-2))^2) = sqrt((-5)^2 + (12)^2) = sqrt(25 + 144) = sqrt(169) = 13 units
Therefore, the distance between the points (4, -2) and (-1, 10) is 13 units.

6/10 + 20/100 = 8/10
6/10 can be simplified but we don't need to worry about it right now. We only need to worry about simplifying 20/100:
20/100 → 10/50 → 5/25 → 1/5
Find common denominators
1/5 → 2/10
6/10
Now, add.
6/10 + 2/10 = 8/10
Therefore, the equation is true.

The sum of two numbers is 38. The smaller number is eight less than the larger number. What are the numbers?
Answer: 15 + 23 =38
So n + n + 8 = 38
which means n + n = 30
and since the n's are the same, you just cut the 30 in 2 equal pieces. 15 and 15.
So n = 15, n + 8 = 23
15 + 23 = 38 :)

A guitar shop is offering two deals on their guitars. Each guitar is $50 less than its initial sale price. In addition, customers receive a further discount of $3 off each $5 of the sale price. Write a function that represents the final price of a guitar f(x) with an initial price of x. If a guitars initial price was $200, what would it be with the discount?
Answer:
30 dollar discount
Step-by-step explanation:
Using the discount parameters given, the final sale price function of the guitar would be f(x) = x - 0.6x - 30 and the discount on initial price of $200 would be $90
Let initial price = x
First discount :
$50 off :
f(x) = x - 50Second discount :
$3 off each $5 of sale price
3/5 of sale price = 0.6 × (x - 50)Final discount :
0.6( x - 50) = 0.6x - 30The Final sale price :
f(x) = x - 0.6x - 30
Given an initial price, x = 200
Discount on price :
Final discount = 0.6x - 30
Discount on price of x = 200 :
0.6(200) - 30
120 - 30 = $90
Therefore, the discount on the price is $90

Given that the measure of ∠x is 120°, and the measure of ∠y is 60°, find the measure of ∠z.
Answer:
60 degrees
Step-by-step explanation:
angle y is vertically opposite to angle a, (we can call it.)
angle x is supplementary to the other angle inside the triangle, which we can call angle b.
so, angle a is 60 degrees, as vertically opposite angles are equal
angle b is 60 degrees as supplementary angles = 180
based of the sum of angles in a triangle is 180 theorem;
60+60+unknown= 180
so unknown is 60 degrees
Stephen got a new job through an employment agency. The job pays $41,236 per year. The agency fee is 15% of the first 5 weeks pay.
How much will Stephen pay to the agency?
Answer:
$594.75
Step-by-step explanation:
Given
yearly salary of Stephen= $41,236
No of weeks in a year = 52
Therefore, one week salary of Stephen = $41,236/52 = $793
to get one week salary divide total salary by number of weeks
5 weeks salary of Stephen = 5*793 = $ 3,965
agency fees = 15% of Stephen's 5 week salary
(15/100)*($ 3,965) = $594.75
Therefore, Stephen has to pay $594.75 to the agency.
