Use the drop-down menus to complete each equation so the statement about its solution is true.

babymother [125]

Answer:

7x+1
6x+1
7x+5

Step-by-step explanation:

No Solutions

There will be no solutions when the left side is inconsistent with the right side:

2x +5 +2x +3x = 7x +1

7x +5 = 7x +1 . . . . . . no value of x will make this true

One Solution

There will be one solution when the left side and right side are not inconsistent and not the same.

2x +5 +2x +3x = 6x +1

7x +5 = 6x +1

x = -4 . . . . . . . . add -6x-5 to both sides

Infinitely Many Solutions

There will be an infinite number of solutions when the equation is true for any value of x. This will be the case when the left side and right side are identical.

2x +5 +2x +3x = 7x +5

7x +5 = 7x +5 . . . . . true for all values of x

Comment on these solutions

You have not provided the contents of any of the drop-down menus, so we cannot say for certain what the answers should be--except in the case of "infinitely many solutions." For "no solutions", the coefficient of x must be 7 and the constant must not be 5. For "one solution" the coefficient of x cannot be 7, and the constant can be anything.

What is the perimeter of the figure?

aleksley [76]

Answer:

B. 21.1 yd

Step-by-step explanation:

The perimeter of the figure is the sum of all its three sides.

Take note that the dotted line is not a side length of the figure.

The side lengths are 9 yd, 5 yd, and 7.1 yd.

Therefore, the perimeter of the figure = 9 + 5 + 7.1

Perimeter = 21.1 yd.

Also, take note of the unit of the perimeter. Unit of the perimeter would not be squared. Only area has a unit that is squarred.
