You could use 10, 6 and 7.

Using ten would have them all equal 50, using 6 would have them all equal 30 and using 7 would have them all equal 35.

Hope this helps!

You can use 10, 5, or 20
If N=10 substitute n with 10, and it should look like this: 2(10)+3(10)= 5(10)
^ ^ ^
20+30 =50
Do that to the rest of the numbers in order to substitute N.

The relation t relates x to y. To determine if it is a function, see if one x value can give two different y values. Since each x value only has one y value, the relation is a function. To check if the inverse is a function, see if any one y value will give multiple x values. By inversing t, there are two values of x for the value of y = -4 (x = 4 and x = 6), so this is NOT a function.

Answer: Relation t is a function. The inverse of relation t is NOT a function.

Sandra is a real estate agent and rams 5000 commission on the selling of a 62,000 house. what is the percent of commission she r

sveta [45]

To find a percent, you use this simple formula:
5000/62000 = x/100

In this case, x is going to be your percent of commission.

So, to find this, you first divide 5000 by 62000, which is about equal to 0.08.

Now your equation looks like this:
0.08 = x/100

Next, you multiply both sides by 100 to reverse the operation. Now, your equation will look like this:

8 = x

So, the answer is 8%.

So the answer is 30 packages but I did 25 times 20 = 500 and then 25 times 10 = 250
So. 30 = 750

please help!! Drag each pair of equations to show whether the system has no solution, one solution, or infinitely many solutions

Vanyuwa [196]

For the given system of equations, considering different systems are split by ;, we have that:

No solutions: 3y = x + 2, 9y = 3x + 7; y = 2x + 3, y = 2x + 5

One solution: 2y = 3x, -5y = -10x,; x = 6, y = 9.

Infinitely many solutions: y = 5x + 2, 3y = 15x + 6.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

It's equations can be written in the format:

Ax = b

Using the above format, we have that:

If A is different from zero, the system has one solution.

If A is zero and B is different of zero, the system has no solutions.

If both are zero, the system has infinite solutions.

At the first system, multiplying the first equation by -3 and adding with the second, we end up with:

0y = 0x + 2

0 = -2

Which is a false statement, hence it has no solutions.

At the second system, the equations are multiples, hence it has infinite solutions.

At the third system, the coefficients are not zero and are not multiples, and it has one solution.

In the fourth system, the one solution is already given.

At the fifth system, we have that:

2x + 3 = 2x + 5

0x = 2

Hence no solutions.

Select the type of equations

olya-2409 [2.1K]

Two lines are "inconsistent" if they are parallel. They are "equivalent" if they are the same line. Otherwise, they are "consistent."

Your first 3 graphs show "consistent" equations.

The 4th graph shows "inconsistent" equations.

The solution shown on the 5th graph is where the lines intersect, near point
