Answer:

No solution

Infinitely many solutions

One solution

Step-by-step explanation:

The first expression:

           -2(3x  - 1) = -6x -1

  Expand the parentheses;

           -6x + 2  = -6x -1

             -6x + (-6x) = -1 -2

                 0 = -3

This problem has no solutions

Second expression:

          2(3x-1) = 6x -2

  Expand the parentheses;

          6x - 2  = 6x -2

           6x -6x = -2 + 2

             0 = 0

This problem has infinitely many solutions

Third expression:

2(3x - 1) = -6x -2

    Expand the parentheses;

       6x -2 = -6x - 2

        6x + 6x = -2 + 2

           12x = 0

               x  = 0

This equation has only one solution

Answer:

∠m=124°

Explanation:

There are a few different ways that you could go about this but the simplest way is to first notice that Angle n is congruent to the angle above it. That tells us that n = 56 degrees. Because angle m and n are supplementary angles their sum needs to add up to 180. So if we subtract 56 from 180 we get 124 degrees, and there is your answer.

Answer:

No

Step-by-step explanation:

Because in the number 15.8, it is equal to 15.80. 80 is more than 17.

15.17 is not greater than 15.8. Meredith statement is wrong.

A number system is defined as the representation of numbers by using digits or other symbols in a consistent manner.

We need to compare both the numbers 15.17 and 15.80.

For comparing two number we need to check the integer part and decimal part.

The integer part  is same for both the numbers. so let us move towards decimal part. in tenth place 15.17 has 1 and for 15.80 it has 8.

We know that 8 is greater than 1.

Hence 15.8 is greater than 15.17. Merediths answer is wrong.

Answer: The surface area of the planter will be 120.5 square feet.

Step-by-step explanation:  in our shape, we will have 5 sides. The base and the four sides going up from each edge of the base.

The base will be 7 x 5 = 35 square feet.

The front and back side will each be 7 x 0.75 = 5.25 square feet.

The left and right side will each be 5 x 0.75 = 3.75 square feet.

If we add up the 5 faces we get:

35 + 5.25 + 5.25 + 3.75 + 3.75 = 120.5 square feet

Answer:

Your Answer Would be the 3rd Option.

Step-by-step explanation:

The Initial Value is : 4. All you have to do is look for when the x = 0

ROC: 1/2. Minutes =x, Inches= Y. To find ROC, take

Y2 - Y1

----------

X2 - Y1

Replacing those with numbers:

5 - 4

-------

2 - 0

Your ROC is 1/2 .

Equation:

y= 1/2x + 4

Know that The 4 is the initial value, so it's always in that spot. Your ROC is always Next to the x, which also means it's the slope.

Step-by-step explanation:

when the number is between those boxes whether it's negative or positive, it's automatically a positive.

The line that has a constant of proportionality of 5 between y and x is: line A.

The constant of proportionality of a proportional relationship is found using the formula:

Constant of proportionality, k = y/x, where (x, y) is any point on the proportional graph.

Find the constant of proportionality for line A using a point, (1, 5):

Constant of proportionality, k = y/x = 5/1 = 5

Find the constant of proportionality for line B using a point, (3, 5):

Constant of proportionality, k = y/x = 5/3

Find the constant of proportionality for line C using a point, (3, 2):

Constant of proportionality, k = y/x = 2/3

Therefore, the line that has a constant of proportionality of 5 between y and x is: line A.

T, S, U

Step-by-step explanation:

Answer:

U S T

Step-by-step explanation:

The largest angle is going to be opposite the longest side. It stands to reason that the two arms that define the enclosed angle (t) have to have their arms stretched further away from each other in order to accommodate T. So T is the largest angle.

By a similar line of reasoning, the second largest angle is opposite the second largest side. S is the second largest angle.

The smallest angle is opposite the smallest side.
