if 4(x-1)=8(x-2),then x=​

Answers

Answer 1

4(x-1)=8(x-2)

multiply the first bracket by 4

(4)(x)=4

(4)(-1)=-4

multiply the second bracket by 8

(8)(x)=8x

(8)(-2)=-16

4x-4=8x-16

move 8x to the other side ( in other words combine like terms)

sign changes from +8x to -8x

4x-8x-4=8x-8x-16

-4x-4=-16

move -4 to the other side

-4x-4+4=-16+4

-4x=-12

divide both sides by -4 to get x by itself

-4x/-4=-12/-4

x=3

answer:

x=3

Answer 2

Answer:

x = 3

Step-by-step explanation:

4( x - 1) =8

4x - 4 = 8

   + 4  + 4

4x = 12

x = 3

8 ( x - 2 )

8 ( 3 - 2 )

24 - 16

= 8

Well, we know for the first polygon that the short side of the rectangle is 3 and for the second polygon the short side is 6, this means that for the second polygon, all sides will be double of the other side. 2 times the long side of the first rectangle is 18, this is why x = 18.

James and Eric each mix 6 pitchers of lemonade. James makes 26 fluid Ounces of lemonade per pitcher, and Eric makes 32 fluid Ounces of lemonade per pitcher. They combine their lemonade and pour all of it into glasses. They fill as many glasses as possible with 8 fluid Ounces each. They pour the remaining lemonade into the last glass.​

Answers

The number of fluid ounces of lemonade made by James and Eric is a

multiple of the number pitchers mixed.

Possible responses are as follows;The number of glasses filled = 43 glassesThe volume of lemonade in the last glass = 8 fluid ounces

Reasons for arriving at the above responses:Given and derived parameters;

The number of pitchers James and Eric mix = 6 pitchers each

Number of fluid ounces of lemonade James makes per pitcher = 26 fluid Ounces

Volume of lemonade Eric makes per pitcher = 32 fluid ounces

Solution:

Volume of lemonade James makes = 26 fluid Ounce × 6 = 156 fluid Ounces

Volume of lemonade Eric makes = 32 fluid ounces × 6 = 192 fluid Ounces

Total volume of lemonade made by James and Eric = (156 + 192) fluid Ounces = 344 fluid ounces

Volume of lemonade per glass = 8 Ounces

Number of glasses filled = 344 fluid Ounces ÷ 8 Ounces/glass = 43 glasses

Therefore, given that the number of glasses of 8 ounces of lemonade that can be filled using the 344 fluid ounces is exactly 43 glasses, we have;

The last glass is the 43rd glassVolume of lemonade in the last glass is 8 fluid ounces

Find the slope, if it exists, of the line containing the pair of points.
(8,-6) and (3,9)

Answers

Answer:

The slope is -3

Step-by-step explanation:

the equation for finding the slope between two different points is:

M= (y2-y1)/(x2-x1)

Or in other words the change in y over the change in x.

M= (9+6)/(3-8) = 15/-5 = -3.

(sidenote: I added 9 and 6 for the change in y because you cannot subtract a negative number. Instead you have to add it.)

D. x = 3

Step-by-step explanation:

We would like to find out for what value of x does f(x) = g(x). This is essentially the same as asking us to find the x-value for which f(x) = k, where k is some number, and g(x) = k, as well.

Looking at the two tables provided, we notice that when x = 3, both f(x) and g(x) equal -2. So, the answer is D.

The difference between two whole numbers is 9. Twice the smaller number is 6 more than the larger. What is the smaller number?

Answers

Answer = 3
Explanation:
27/3= 9
3x2= 6

The smaller number is 15

let

the larger number = x

the smaller number = y

Therefore,

The difference between the two whole numbers is 9 can be express as follows:

x - y = 9

Twice the smaller number is 6 more than the larger. Therefore,

2y = x + 6

Combine the equation.

x - y = 9

-x + 2y = 6

y = 15

x - 15 = 9

x = 9 + 15

x = 24

Therefore,

The larger number = 24

The smaller number = 15
