How can you tell if an equation has one solution, infinitely many solutions, or no solution?​

Answers

Answer 1
Answer:

Answer:

No Solutions

There is no possible value for x that could make this true. If you take a number and add 4 to it, it will never be the same as if you take the same number and add 3 to it. Such an equation is called a contradiction, because it cannot ever be true.

How do i simplify each fraction 5/10 4/12 3/9 how do i solve by
doing what steps

Answers

The simplification of given fractions 5/10, 4/12, 3/9  are 1/2, 1/3, 1/3.

What are fractions?

A fraction is a part of a whole. In arithmatic, the number is expressed as a quotient, in which the numerator is divided  by denominator.

Now the given fractions are,

5/10, 4/12, 3/9

Now to simplify each fraction we have,

5/10 = 5/(5x2)

or, 5/10 = (5/5)(1/2)

or, 5/10 = 1/2      

Similarly,

4/12 = 4/(4x3)

or,4/12 = (4/4)(1/3)

or, 4/12 = 1/3

Similarly,

3/9 = 3/(3x3)

or, 3/9 = (3/3)(1/3)

or, 3/9 = 1/3

Hence,The simplification of given fractions 5/10, 4/12, 3/9  are 1/2, 1/3, 1/3.

5/10 divide each number by 5, 5 divided by 5 is 1 and 10 divided by 5 is two so it would be 1/2

4/12 divide each number by 4, four divided by 4 is 1, and 12 divided by 4 is 3 so it would be 1/3

3/9 divide each number by 3, 3 divided by 3 is 1, and 9 divided by 3 is 3 or it would also be 1/3

An artificial lake is in the shape of a rectangle and has an area of 9/20 square mile. The width of the lake is 1/5 the length of the lake. What are the dimensions of the lake?

Answers


We know that the area of a rectangle can be written as: length x width

so:

l x (1/5) = 9/20

9/20 x 5/1 = 45/20, which can be reduced to 9/4

So the length is 9/4 miles

Create a list of 8 values with a mean of 26. Justify your response.

Answers

Essentially, if  want to list some values with a given mean, you can assume that they all have this value, so a correct answer will be:

26,26,26,26,26,26,26,26,

You can also vary the values, as long as their sum remains the same (the sum and the number of values decide the mean).

For example, you can add one and remove one:
27,25,26,26,26,26,26,26,
