What is a linear equation?An equation of the form ax+by+c=0 is called a linear equation where a, b and c are real numbers.
According to the question
3x+y=3.95.......(1)
2x+2y=3.10.......(2)
Multiply equation (1) by 2 on both sides
6x+2y=7.90.....(3)
Subtracting the equation (2) from equation(3)
4x=4.80
x=1.20
So, y = 0.35
So, the price for 1 scoop of ice cream =$1.20
The price for 1 topping = $0.35
Hence, the price for 1 scoop of ice cream and price for 1 topping is $1.20 and $0.35 respectively.

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 4 large boxes and 8 small boxes has a total weight of 169 kilograms. A delivery of 2 large boxes and 3 small boxes has a total weight of 71 kilograms. How much does each type of box weigh?
Answer:
weight of large box=15.250 kgm
wight of box=13.500 kgm.
Step-by-step explanation:
let weight of large box=x kgm
and weight of small box=y kgm.
4x+8y=169
2x+3y=71
multiply by 2
4x+6y=142
subtract from first
2y=27
y=27/2=13.500 kgm
4x+8(27/2)=169
4x+108=169
4x=169-108
4x=61
x=61/4=15.250 kgm

someone please help or i’ll be failing geometry this year
Step-by-step explanation:
I don't know what constructions you were taught.
a "similar" triangle is a triangle with exactly the same angles as the other triangle, but the lengths of all sides are stretched or shortened by the same scaling factor f.
by saying 1:2 she means the second triangle should have sides with twice the lengths of the first triangle (f=2).
and the extra challenge - same basic thing. she allows you to pick one of the two triangles as reference. and then you need to draw a third triangle (again with the same angles) with the side lengths extended by the scaling factor f of 4/3.
I would draw the triangles right on top of each other with the same starting corner (let's call it A) for all 3.
we would get the triangles ABC, AMN and AXY.
the points B and C would be then halfway on AM and AN.
and M and N would then a bit before X and Y on AX and AY.
the beauty is, you only need to construct 2 sides of every new triangle down to the new endpoints. the third side is automatically scaled correctly, and you only need to connect these new endpoints.
let's assume you draw a triangle (just very simple) ABC with all side lengths being 3. so, AB=3, AC=3, BC=3.
now you draw AMN by extending AB and AC to a side length of 6 (f=2) creating M and N, and you connect M and N.
and then you can create the third triangle AXY by extending AM and AN by a factor of 4/3 to side lengths of 8 (4/3 × 6 = 8) creating new end points X and Y. and you connect X and Y.
and that is it. all 3 triangles are similar (the same angles), and all sides of a triangle have the same length ratio to the sides of the other triangle(s).
An auto analyst is conducting a satisfaction survey, sampling from a list of 10,000 new car buyers. The list includes 2500 Ford buyers, 2500 GM buyers, 2500 Honda buyers, and 2500 Toyota buyers. The analyst selects a sample of 400 car buyers by randomly sampling 100 buyers of each brand. What sampling method is used?
Answer: Stratified random sampling.
Step-by-step explanation:
In a simple random sampling, every one has an equal chance of being chosen. This case is quite different.
In this case, since the analyst selects a sample of 400 car buyers by randomly sampling 100 buyers of each brand, this is a stratified random sampling since the outcome was already divided into 100 cars for each brand.

Answer:
3 ft , 4 ft and 5 ft is a triangle.
Step-by-step explanation:
The first is not a triangle as 4 + 4 = 8 so triangle cant be drawn with these lengths.
Also third: 3 + 3 < 7 and last one 4 + 5 < 10 so neither are triangles.
A triangle has one angle that measures 19 degrees, one angle that measures 118 degrees, and one angle that measures 43 degrees.
What kind of triangle is it?
A. right triangle
B. obtuse triangle
C. acute triangle
D. equilateral triangle
Answer:
B. obtuse triangle
Step-by-step explanation:
Obtuse triangles are triangles with one obtuse angle and two acute angles. Define obtuse angles as angles over 90 degrees and acute angles as angles less than 90 degrees.
In this triangle:
118 degrees - obtuse angle
19 degrees - acute angle
43 degrees - acute angle
Thus, this triangle is an obtuse triangle.

6, 8, 11, 12, 2x – 8, 2x + 10, 35, 41, 42, 50
are in ascending order. If the median is 25,
find the value of x.
Ans: 12
Answer:
12
Step-by-step explanation:
(2x-8+2x+10)/2 = 25
(4x+2) = 2×25
4x+2 = 50
4x = 50-2
4x = 48
x = 48/4
x = 12
Answer:
x = 16.5 as the median in this term is 2x-8
and 2x-8 = 25
25+8=2x
33=2x
x=[tex]\frac{33}{2}[/tex]
= 16.5
Step-by-step explanation:
this answer says 12 which is false

If PR is 4, WQ is 8, and QR is 5, SP = ___ units
Answer:
From the attached graphic, we can see:
(SP + PR) * PR = (WQ + QR) * QR
SP * PR + PR^2 = WQ * QR + QR^2
4 SP + 4*4 = 8 * 5 + 25
4 SP + 16 = 65
4 SP = 49
SP = 49 / 4

4x + 5y = 34
solve for x and y
Help help
Answer: y=2 and x=6
Step-by-step explanation:
x=3y
4x+5y=34
From equation ( 1) x=3y thus substituting in eqn(2)
4(3y)+5y=34
12y+5y=34
17y=34
y=34÷17=2
Thus y=2
Putting y=2 in eqn(1)
x=3y
x=3(2)
x=6
The histogram shows the number of hours that students in a class slept last night. How many students slept at least 8 hours?
Answer:
10 students slept at least 8 hours
Step-by-step explanation:
The third group of numbers, 8-11 hours of sleep, begins in 8, making it the minumum number group that we can use. The second eligigble group is 12-15 hours because it garuntees at least 12 hours of sleep. When add the 8 students who sleep for 8-11 hours to the 2 students who sleep 12-15 hours, we get 10 students who sleep 8+ hours frequently.
The number of students who had at least 8 hours of sleep is 11 students.
What is a histogram?The graphic representation of data points arranged into user-specified ranges is called a histogram. The histogram, which resembles a bar graph in appearance, condenses a data series into an intuitive visual by collecting numerous data points and organizing them into logical ranges or bins.
From the given histogram the y-axis represents the frequency of students and the x-axis represents time in hours.
The statement of having at least 8 hours of sleep is having sleep for 8 or more hours.
Therefore, From the histogram, the number of people having at least 8 hours of sleep is 8 + 3 = 11.

Determine the volume of the space in the tank that still needs to be filled with water if the water is ⅓ ft. Deep
Answer:
11 1/9 ft^3
Step-by-step explanation:
find the complete question in the attached image
volume of the tank = length x width x height
2 x 5 x 1 2/3
2 x 5 x 5/3 = 50/3 = 16 2/3 ft^3
If the tank is 1/3 filled with water, the volume that needs to be filled with water is 1 - 1/3 = 2/3
volume that needs to be filled with water = 2/3 x volume of the tank
2/3 x 50/3 = 11 1/9 ft^3

The manager of a department store wants to know if any of the company's 281 employees would buy a reduced gym membership. The manager surveyed 70 randomly chosen employees, and 50 reported they would buy a reduced gym membership.
Answer: 201 employees
Step-by-step explanation:
Question wants to know the predicted number of employees from the total number that would buy a reduced gym membership.
Going by the number of employees from the sample of 70 that said they would prefer a reduced membership, one can estimate a predicted value for the number of employees from the total population of 281 that would want the same.
Find the percentage that would want a reduced membership from the sample:
= 50 / 70 * 100%
= 71.43%
Apply this to the total population:
= 71.43% * 281
= 200.7
= 201 employees
