How many solutions does an equation have when you isolate the variable and it equals a constant?
OLEGan [10]

1 solution is available when variable equals a constant.

Answer: Option B.

<u>Explanation:</u>

You will be able to determine if an equation has one solution (which is when one variable equals one number), or if it has no solution (the two sides of the equation are not equal to each other) or infinite solutions (the two sides of the equation are identical).

The ordered pair that is the solution of both equations is the solution of the system. A system of two linear equations can have one solution, an infinite number of solutions, or no solution. If a consistent system has exactly one solution, it is independent.

What is the average of 7.75, 7.25, 7.33, 7.6
tatuchka [14]
Average is just the total divided by the number of things you added up.

You've been given 4 numbers.

So just add 7.75+7.25+7.33+7.6 and then divide that by 4.

the answer is therefore 29.93/4

=7.4285

You can check if that seems right by just looking at the numbers, the average will be inbetween the smallest and largest numbers, so it matches up.

qwelly [4]
Setup Average Equation:
_____________________
Average=Sum of our 4 numbers + unknown number of x
                ____________________________________
                                          Total Numbers
15 = 3 + 19 + 8 + 32 + x
       ______________
                      5
Cross Multiply
___________
3 + 19 + 8 + 32 +  = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:
___________________________________________
x + 62 - 62 = 75 - 62
x = 13
