Solve for x. 3x−82=x−6

20 Points

Answers

3x-82 = x-6

subtract 1 x from each side

2x -82 = -6

add 82 to each side

2x = 76

divide both sides by 2

x = 76/2 =38

x = 38


Check:

3(38)-82 = 38-6

3*38 = 114, 114-82 =32 and 38-6 = 32 32 = 32 TRUE

Kevin is 14 inches taller than George. The difference between Kevin and Richard is two inches less than between Richard and George. Kevin at 6'6" is the tallest. How much tall are Richard and George?

Answers

 1 foot is 12 inches which makes 14 1.2

6.6-1.2= 5'4 george

richard is 6'0







Richard is 6'1" and George is 5'11" tall.

To calculate Richard and George's heights, we start with Kevin being 6'6" and 14 inches taller than George, meaning George is 5'4".

The difference between Kevin and Richard is 2 inches less than between Richard and George, making Richard 6'1" and George 5'11".

I'm learning about Equivalent systems of equations, please help!

Answers

OK to solve this, we have to solve each system presented through elimination or substitution and find which one is equivalent to that of the teacher's!

First let's solve for the teacher's:
-2x+5y=10
-3x+9y=6
Solve by substitution (I think elimination might be easier to do for this one, but I don't really remember 100% sorry!)
Isolate the x (or y) variable in the first equation
-2x+5y=10
-2x=10-5y
[tex]x= \frac{10-5y}{-2} [/tex]
Substitute x into the next equation and solve for y
-3(10-5y/2)+9y=6
3*10-5y/2+9y=6
(multiply both sides by 2)
3(10-5y)+18y=12
30-15y+18y=12
30+3y=12
3y=-18
y=-6

Substitute in x
x= -10-5(-6)/2
x=-20

SELINA'S ANSWER
(8,4)

So neither Goku or Selina got the same answer as the teacher
Here I go

The teacher's system is
-2x + 5y = 10
-3x + 9y = 6

To find the system that equals to the teachers solution, we must solve all three of them. (Yeah good luck)

Let's start solving the teacher's system

We need to solve -2x + 5y = 10 for x
-2x + 5y = 10
-2x = 10 - 5y
Divide both sides by -2
-2x/-2 = (10-5y)/-2
x = 5/2 y - 5
Now we need to substitute 5/2 y -5 for x in -3x +9y = 6
We gonna replace 5/2 y -5 by x
-3x + 9y = 6
-3(5/2 y - 5) + 9y = 6
Simplify both sides (I used a calculator)
3/2 y + 15 = 6
3/2 y = 6 - 15
3/2 y = -9
To find y, we need to divide both sides by 3/2
3/2 y/3/2 = -9/3/2  (I used a calculator)
y = -6
It easier to find x since we already find y
So, let's find x by substitute -6 for y in x=5/2 y - 5
What does that mean? We gonna replace the value of y which is -6 everywhere we find y (I hope it makes sense)
x = 5/2 y - 5
x = 5/2 (-6) - 5 (use a calculator)
x = -20

Therefor,
x = -20 and y = -6
This is the teacher's solution so we gonna solve the others and see what they have :)

----------------------------------------------
Selina's system

-5x + 14y = 16
-3x + 9y = 12

So, we need to solve -5x + 14y = 16 for x
-5x + 14y = 16
-5x = 16 - 14y
Divide both sides by -5
-5x/-5 = (16 - 14y)/-5
x = 14/5 y + -16/5     (It looks messy here)
To continue, we need to substitute 14/5 y + -16/5 for x in -3x + 9y = 12
-3x + 9y = 12
-3( 14/5 y + -16/5) + 9y = 12
Simplify both sides
3/5 y + 48/5 = 12
3/5  y = 12 - 48/5
3/5 y = 12/ 5
To find y, we just need to divide both sides by 3/5
3/5 y/3/5 = 12/5/3/5  (cancel 5, then divide 12 by 3 = 4)
y = 4
We gonna use the value of y to find x
We gonna do that by substitute 4 for y in x = 14/5 y + -16/5
x = 14/5 y + -16/5
We gonna replace y by 4
x = 14/5 (4) + -16/5 (used a calculator)
x = 8
Therefore,
x = 8 and y = 4
So, Selina system doesn't equal to the teacher's system.
-----------------------------------
Goku's system

again, I used the same steps to solve all of them.

x - 3y = -2
-2x + 5y = -7

We need to solve x - 3y = -2 for x
x - 3y = -2
x = -2 + 3y
I prefer to let the unknown value leads, so it will be
x = 3y - 2  (it still the same thing :) )
Substitute 3y - 2 for x in -2x + 5y = -7
-2x + 5y = -7
-2(3y - 2) + 5y = -7
-6y + 4 + 5y = -7
-y + 4 = -7
-y = -7 - 4
-y = -11
We cannot leave the y with a negative sign, so we must divide both sides by -1
-y/-1 = -11/-1
y = 11
To find x, we need to substitute 11 for y in x = 3y - 2
x = 3y - 2
x = (3)(11)-2
x = 33-2
x = 31
Therefore,
x = 31 and y = 11
Goku's answer doesn't equal to the teacher's answer.

The function g(x) = –3x2 – 36x – 60 written in vertex form is g(x) = –3(x + 6)2 + 48. Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = –3x2 – 36x – 60? The graph of f(x) = x2 is made narrower. The graph of f(x) = x2 is shifted right 6 units. The graph of f(x) = x2 is shifted down 48 units. The graph of f(x) = x2 is reflected over the y-axis.

Answers

the vertex form of the function gives the vertex as (-6,48). The vertex of f(x)=x^2 is (0,0) so from this information, the vertex is moved LEFT 6 and UP 48. This cancels out two options. The coefficient -3 tells us that the graph is flipped or reflected over the x-axis (negative sign flips graph) and that all y-values will be 3 times as large. Larger y-values for the same x inputs makes the graph narrower.

Chloe wants to cut a 37 in. piece of ribbon into three pieces. The second piece is to be 2 in. longer than the first, and the third piece is to be 3 in. longer than the second. How long will each of the pieces be?

Answers

1st piece = x

2nd piece = x+2

3rd piece = x+2+3 = x+5

37 = x +x+2 + x+5 =

37 = 3x+7

30=3x

x = 30/3 = 10

 1st piece = 10 inches

 2nd piece = 10+2 = 12 inches

 3rd piece = 10+5 = 15 inches

Students use a balance to determine the mass of a marble in 7.5 G of graduated bottle contains 10 milliliters of water when the marble is carefully lowered into the granulated bottle and is completely covered with water the volume of the water containing the marble has increased to 12.5 ml what is the density of the marble

Answers

The volume of the marble = increase in volume of the water = 12.5 - 10 = 2.5 grans.

Denisty of the marble  = mass / volume = 7.5 / 2.5  =  3 grams/millimeter.

Answer:

3 g/ml

Step-by-step explanation:

After the marble was introduced into the graduated bottle, the volume change from 10 ml to 12.5 ml, this means that 12.5 - 10 = 2.5 ml is the volume occupied by the marble.

The mass of a marble is 7.5 g.

Density is defined as follows:

density  = mass / volume =

Replacing with the measures:

density = 7.5/2.5  =  3 g/ml

a male lion needs as much as 15 pounds of food each day or 105 pounds of food each week.how much does a lion need in one year.
I'm just checking i have the answer i just want to check thx

Answers

Final answer:

If a male lion eats 15 pounds of food each day or 105 pounds each week, it would need about 5460 pounds of food in a year. We arrive at this by multiplying the weekly amount (105 pounds) by the number of weeks in a year (52 weeks).

Explanation:

The question is asking how much food a male lion needs in a year if it eats 15 pounds of food each day, or 105 pounds per week. If we want to know how many pounds of food a lion needs for an entire year, we would need to multiply that weekly amount by the number of weeks in a year. There are 52 weeks in a year. So, we take 105 pounds of food per week and multiply it by 52.

Calculation: 105 × 52 = 5460

So, a male lion needs about 5460 pounds of food in a year.

Angie is wrapping a present for her best friend. The box is 16 inches long, 12 inches wide, and 3 inches high. How many square inches of wrapping paper does Angie need for her present

Answers

Alright, you will need to find the areas of 3 of the sides(i.e. Top/Bottom, Left/Right, Front/Back), to do so let's go through multiplying these:

Since we're not looking for the Volume, we'd just multiply one variable by another, for instance:

Bottom = Length * Width
x = 16 * 12 | 16 * 12 = 192

Left = Length * Height
x = 16 * 3 | 16 * 3 = 48

Front = Width * Height
x = 12 * 3 | 12 * 3 = 36

Now that we know 3 of the sides, we then multiply each by 2 since there's another side to this box(in other words, we'd be adding both sides together, multiplying it by 2 still gives you the same answer though).

Bottom + Top, or Bottom * 2
192 + 192 = 384 | or | 192 * 2 = 384

Left + Right, or Left * 2
48 + 48 = 96 | or | 48 * 2 = 96

Front + Back, or Front * 2
36 + 36 = 72 | or | 36 * 2 = 72

Adding these together gives you the answer you're looking for. ^ ^
384 + 96 + 72 = 552

So, the answer should be that Angie needs 552 square inches of wrapping paper for her present. I hope that helped, have a great rest of your day!

Answer:

Yes the budget is reasonable.

A bus service drives passengers between Milwaukee and Chicago every day for eight times each day.

The distance between the two cities is 89 miles.

So, total distance covered per day = [tex]89\times8=712[/tex] miles.

Total distance covered in 28 days = [tex]28\times712=19936[/tex] miles.

As give, The company's budget allows for 28,000 total miles for February.
