The ratio of the coefficient is the same so it will be the infinite solution of a given system of the equation so option (C) will be correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
A linear equation could contain more than one variable. When the maximum power of the variable is constantly uni, an equation is said to be linear.
Given the set of equation
4x - 2y = 12
20x - 10y = 160
The ratio of x coefficient = 4/20 = 1/5
The ratio of y coefficient = -2/-10 = 1/5
The ratio of the constant term = 12/160 = 1/5
Since all ratios are the same so there will be an infinite number of solutions.
The question was incomplete, but the complete question is given below.
How many solutions does this system have?
4x – 2y = 12
20x - 10y = 60
A. None
B. One
C. Infinite

Answer:
5,5,10, and 60
Step-by-step explanation:
Find the remaining numbers
80-60= 20
10 + 10 = 20
Break it up to get 4 numbers total
5 + 5 + 10 = 20
20 + 60 = 80

z+w−3=k
6z−10w=8
Answer:
if your looking for z it is 5/8k+2.375
Step-by-step explanation:
Answer:
Step-by-step explanation:
Please, include the instructions.
I'm assuming you want to solve this system of linear equations for z and w, assuming that k is an unknown constant.
Use the method of elimination by addition and subtraction. To eiiminate w, multiply all four terms of the first equation by 10, obtaining:
10 z + 10w - 30 = 10k
6z - 10 w = 80
Then 16z - 30 - 80 = 10k, or
16z -110 = 10k, Simplifying this, we get:
10(k + 11)
z = ---------------
16
Substituting this expression for z into the first equation, we get:
(10/16)(k + 11) + w - 3 = k. We must solve this for w:
-(10/16)(k + 11) + w - 3 = k), or
-(10/16)(k + 11) - w + 3 = -k
Then -(10/16)(k + 11) + 3 + k = w
and so the solution, in terms of the unknown constant k, is
10(k + 11)
( --------------, -(10/16)(k + 11) + 3 + k )

Answer: Yes. It is inversely proportional.
Step-by-step explanation:
In your question, the constant of proportionality already jump out at us which is to get y, we have to multiply x by 7. Therefore the constant of proportionality is y=7x.

Answer: QPR=31
Step-by-step explanation: first you would combine 3x and 7x which equals 10x. Then you combine -95 and -38 which equals -133. then you set up an equation like 10x - 133 = 47. Add 133 to both sides. 10x = 180. Divide both sides by 10. X= 18. 18 times 7 equals 126. 126 - 95 equals 31

−5x + (−2) = −2x + 4
Answer:
x = -2
Step-by-step explanation:
Remove brackets
-5x - 2 = -2x + 4
Rearrange by collecting the like terms and putting them on either side
-5x + 2x = 4 + 2
Simplify
-3x = 6
Divide both sides by -3 to make x on its own
-3/-3x = 6/-3
x = -2
Sally built a rectangular prism using cubic units. What is the volume of the rectangular prism Sally built?
Answer:
64
Step-by-step explanation:
The volume of rectangular prisms is measured by l*w*h
And by counting the units of the length, width, and height are all 4 units long.
So take the numbers and plot them into the formula
4*4*4 = V
16 * 4 = V
64 = V
The prism is 64 cubic units.
Jed is baking shortbread for a bake sale. The recipe calls for 1 1 4cups of flour and 1 2stick of butter. How many cups of flour will Jed need if he uses 3 sticks of butter?
Answer: [tex]7\dfrac12[/tex] cups of flour is required for 3 sticks of butter.
Step-by-step explanation:
We assume that quantity of flour is proportional to butter.
Given : The recipe calls of [tex]1\dfrac14[/tex] cups of flour and [tex]\dfrac12[/tex] stick of butter.
Let [tex]x_1=1\dfrac14=\dfrac{5}{4}[/tex] [tex]y_1=\dfrac{1}{2}[/tex]
For [tex]y_2=3[/tex] , we will find [tex]x_2[/tex] by using formula of direct proportion: [tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]
[tex]\dfrac{\dfrac{5}{4}}{\dfrac12}=\dfrac{x_3}{3}\\\\\Rightarrow\ \dfrac{5}{2}=\dfrac{x_3}{3}\\\\\Rightarrow\ x_3=\dfrac{5}{2}\times3= \dfrac{15}2=7\dfrac12[/tex]
Hence, [tex]7\dfrac12[/tex] cups of flour is required for 3 sticks of butter.
15/2 cups of flour!

What is the answer for t?
4(t + 3) = 24
Answer:
3
Step-by-step explanation:
4(t +3)=24
4t +12 =24
4t =24 - 12
4t =12
t =12 :4
t =3
Answer:
t = 3
Step-by-step explanation:
Original Equation:
4(t + 3) = 24
Use distributive property
4 x t = 4t
4 x 3 = 12
Your equation:
4t + 12 = 24
Subtract 12 from both sides
4t = 12
Divide both sides by 4
t = 3

Find the slope of the line that passes through the points (2, 4) and (6, 12)
Answer:
Slope = 2
Step-by-step explanation:
To find slope, you use the formula [tex]\frac{y1-y2}{x1-x2}[/tex]
[tex]\frac{4-12}{2-6} = \frac{-8}{-4} = 2[/tex]
So the slope = 2

If x= 2 what does y equal
Answer:6
Step-by-step explanation:
4.8(x)+1.2(y)=2.4
y would equal -6.
4.8(2)+1.2(y)=2.4
9.6 + 1.2y = 2.4 subtract 9.6 from both sides
1.2y = - 7.2 divide by 1.2 on both sides
y = -6

9. Peyton is collecting data on the lunch habits of students at Hyattsville Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Hyattsville Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch?*
Answer: Around 1000 students would buy a schoo lunch.
Step-by-step explanation:
We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.
In total we have 20 + 14 = 34 students, this will be our 100%.
The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.
p1 = (14/34)*100% = 41.18%
And the percentage of students that buy lunch at school can be computed in the same way:
p2= (20/34)*100% = 58.82%
Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.
Then the exact number will be:
N = (58.82%/100%)*1700 = 1000
Around 1000 students would buy a schoo lunch.

PLS HELP FIND ANGLE MEASUREMENTS
Answer:
From my observations, AOB looks like an isosceles triangle, so A=18 and B=18. Since a triangle must add up to 180. We do 180-18-18=144. O= 144. Then, triangle BOC looks like an isosceles triangle as well. So, we do 180-144= 36 so O = 36 and then we 180-36=144/2 because two sides have the same angles giving us 72 degrees for angles B and C = 72 and for O= 36
So,
x = 72
y = 36
