4x+y=6
x-2y=6
Answers
x=2 and y=(-2)
hope it helps...
Answer:
y = ( -2 )
x = 2
Step-by-step explanation:
4x + y = 6 ⇒ ( 1 )
x - 2y = 6 ⇒ ( 2 )
x = 6 + 2y ⇒ ( 3 )
First, let us find the value of y.
For that, we can replace x with ( 6 + 2y ).
Let us use equation 1 for that.
4x + y = 6
4 ( 6 + 2y ) + y = 6
24 + 8y + y = 6
24 + 9y = 6
9y = 6 - 24
9y = -18
Divide both sides by 9.
y = -2
Now let us find the value of x by replacing y with -2.
For that let us take equation 3.
x = 6 + 2y
x = 6 + 2 × -2
x = 6 - 4
x = 2
i need help on this 6th grade math problem
Answers
Answer: x<17.5
Step-by-step explanation:
Subtract from both sides: x+2.5-2.5<20-2.5
Simplify the arithmetic: x<20-2.5
Simplify the arithmetic: x<17.5
Hope it helps!
Answer: B) 12.5
Step-by-step explanation:
Start by isolating x by subtracting 2.5 from both sides
[tex]x+2.5 < 20\\x+2.5-2.5 < 20-2.5\\x < 17.5[/tex]
This reads as "x is less than 17.5"
D can be eliminated because it is greater than 17.5
C can be eliminated because 17.5 can't be less than itself
So the answer must be B since it is less than 17.5 and greater than A

The production costs, C, in thousands of dollars, for an
energy drink company to manufacture cans of energy
drink is given by the model C(x) = 50 +3.8x -0.0038x^2,
where x is the number of cans of energy drinks produce
in one day, in thousands. The company wants to keep i
production cost at or below $781.12.
Given that x is an element of a subset of the integers,
which of the following constraints satisfy the domain of
C(x)?
The answer choices are in the picture.
Answers
If the company wants to keep its production costs under $781.12 a reasonable domain for the constraint x is -12.9892≤ x ≤ 1012.99.
What are constraints?A constraint is a condition of an optimization problem that should be satisfied the condition.
Let x is an element of a subset of the integers,
C(x) is the production cost, in thousands of dollars
[tex]C(x) = 50 +3.8x -0.0038x^2,[/tex]
This is a vertical parabola open downward (the leading coefficient is negative)
we know that
For the interval [-12.9892, 1012.99] = -12.9892≤ x ≤ 1012.99
The value of C(x) = C(x) < 781.12
That means the production cost is under $781.12
Remember that the variable x (number of tires) cannot be a negative number.
If the company wants to keep its production costs under $175,000 a reasonable domain for the constraint x is -12.9892≤ x ≤ 1012.99

Santos takes the train into the city five days a week for work. For one work week, he kept track of how many minutes long each train ride was: 48, 51, 48, 48, 50
Calculate the mean, median, range, and midrange of the train ride times for the week.
Answers
The mean, median and range of the given data are respectively; 49, 48 and 3.
How to calculate mean, median and range?Formula for mean is;
Mean = Total sum/sample size
Total sum = 48 + 51 + 48 + 48 + 50
Total sum = 245
Sample size = 5
Mean = 245/5
Mean = 49
To get the median, we arrange in ascending order and pick the mid term.
48, 48, 48, 50, 51
Median is mid term which is 48.
Range is difference between highest and lowest term.
Range = 51 - 48
Range = 3

I think it is usefulFor a craft project, you select the four packages of modeling clay and the set of tools shown at the right. If there is a 6% sales tax, what is the total cost?
Answers
Answer:
13.727
Step-by-step explanation:
Explanation
Given: You choose the four packages of modeling clay and the set of equipment indicated on the right for a creative project.
To find: the total cost if there is a 6% sales tax.
We will calculate the total cost of each item and then add.
Tip
The total cost formula is used to combine the variable and fixed costs of providing goods to determine a total.
The formula is: Total cost = (Average fixed cost x average variable cost) x Number of units produced.
Step 1
The cost of 4 packets of clay is given by:
4 x $2.79
Step 2
We will calculate the product:
4 x 2.79 = 11.16
Step 3
We will add the cost of 4 packets of clay and a pack of tools to get the total cost without tax:
$(11.16 + 1.79)
Step 4
We will add the numbers:
11.16 + 1.79 = 12.95
Step 5
The 6% tax on the total price is given by:
6% x $12.95
Step 6
We will calculate the sales tax:
6/100 x 12.95 = 0.777
Step 7
We will add the total cost without tax and tax amount to get the total amount paid:
$(12.95 + 0.777)
Step 8
We will add the amounts:
12.95 + 0.777 = 13.727
Step 9

b) (2 * 3 ) * (1/2)^3 = .75
c) ( 8 * 4 * 11) * (1/8)^3 = .6875
The representation of the volume of the prism in greatest to least volume is third > first > second.
What is volume?Volume is the scalar quantity of any object that specified occupied space in 3D.
For example, the space in our room is referred to as volume.
As per the given cuboid prism.
The volume of the cuboid = length × height × width.
First cube = 1/4 x 3 x 6 x 2 = 9 units³
Second cube = 1/2 x 2 x 3 x 1 = 3 units³
Third cube = 1/8 x 8 x 11 x 4 = 44 units³
So, 44 > 9 > 3.
Hence "The representation of the volume of the prism in greatest to least volume is third > first > second".

What is the area of triangle BCD to the nearest tenth of a square centimeter? Use special right triangles to help find the height. ( Show your work). Will Only Mark Brainliest if answered correctly and No resharing another students answer from brainly or any other websites or you'll be reported.
Answers
Answer:
Area = 21.7 cm² (nearest tenth)
Step-by-step explanation:
A 30-60-90 triangle is a special right triangle. The measures of its sides have a special relationship in that they are in proportion:
shortest leg : longest leg : hypotenuse = 1 : √3 : 2
The side opposite 30° is the shortest legThe side opposite 60° is the longest leg and is √3 times the length of the shorter leg. The side opposite 90° is the hypotenuse and is twice the length of the shorter leg.So we can also write the ratio as [tex]x : x\sqrt{3} : 2x[/tex] where [tex]x[/tex] is the shortest side.
From inspection of the diagram, the shortest side is 5 cm
⇒ BC (height) = 5 × √3 = 5√3 cm
Now we have the height, we can calculate the area.
Area of a triangle = 1/2 x base x height
= 1/2 x 5 x 5√3
= 21.7 cm² (nearest tenth)

C. 3
D. 4
E. 5
Answers
If we substitute 3 into the x values in each equation we can see that the top and bottom is the same value and both sides are also the same value, meaning that it is a parallelogram;
Top and bottom of parallelogram:
2x + 3
2 (3) + 3
= 6 + 3
= 9
And
x + 6
(3) + 6
= 9
And then the two sides;
6x - 5
6 (3) - 5
= 18 - 5
= 13
And
4x + 1
4 (3) + 1
= 12 + 1
= 13
There are two pairs of equal sides which shows that this is a parallelogram.

An alloy weighing 30 lbs is 119 tin The alloy was made by mixing a 15% tin alloy and a 9% tin allov. How many pounds of each alloy were used to make the 11% alloy?
Answers
We let x = pounds of alloy that is 15% tin
The problem is modeled by the equation:
0.11(30) = 0.15x + 0.09(30-x)
The equation means that the amount of tin does not change. Also, the amount of alloy (total weight - weight of 15% alloy) is (30-x).
Solving for x:
3.3 = 0.15x +2.7 - 0.09x
.06x = 0.6
x = 10 lbs
30-10 = 20 lbs
10 lbs. of the 15% alloy and 20 lbs. of the 9% alloy

divide Rs 120 between two students so that one gets 4 times as much as the other
Answers
Answer:
One gets Rs 24 and the other Rs 96.
Step-by-step explanation:
Number of parts = 1 + 4 = 5
So one student gets 1/5 of 120 and the other gets 4/5 of 120
120 * 1/5 = 24
120 *4/5 = 4*24 = 96.
Answer:
One would get 96 and another would get 24
Step-by-step explanation:
So first lets create an equation from the words where 4x is what one students has and x is what another has :
120 = 4x + x
Lets solve this now!
120 = 5x (divide by 5 on both sides)
24 = x (1st Student)
(Multiply by 4 on both side to get the second student)
96 =4x (2nd Student)

What is the value of x in the equation 4 (2x + 14) = 0?
9, 7, -7, -9.
Answers
Answer:
x = -7
Step-by-step explanation:
First step is to expand the left side of the equation. To do this, multiple 4 by each term on the inside of the paratheses.
4 * 2x = 8x
4 * 14 = 56
This gives you the equation:
8x + 56 = 0
Now, get the x term on one side by itself by subtracting 56 on both sides:
8x = -56
And solve for x by dividing both sides by 8:
x = -7
