## What is number of solutions?

Like systems of equations, system of inequalities can have zero, one, or infinite solutions. If the set of solutions includes any shaded area, then there are indeed an infinite number of solutions.

## Where should a line be drawn to make this equation correct 5 5 5 555?

Strike a line on the first “+” and make it “4”. this would make it 545+5+5=555!!

**What is times as many?**

When you multiply, you are often making a comparison between two numbers. In the equation 7 x 5 = 35, the answer 35 is 5 times as many as 7. It is also 7 times as many as 5.

### What are solutions in math?

A solution to an equation is a number that can be plugged in for the variable to make a true number statement.

### How do you find three solutions of an equation?

To find three solutions to this equation, substitute three different numbers and calculate the result for y :

- Set x=0. y=9x−4 becomes: y=(9⋅0)−4. y=9−4. y=5. The first solution is: (0,5)
- Set x=10. y=9x−4 becomes: y=(9⋅10)−4. y=90−4. y=86. The second solution is: (10,86)
- Set x=−10.

**Can Google solve math problems?**

Google Lens It can recognize anything you take pictures of, including math problems. Open the Google App on your phone and tap the camera icon in the search bar. Next, select Homework at the bottom of the screen. Then, just snap a picture of a math problem for an instant answer.

## How do you find no solution?

To find the missing number, compare both sides of the equation. If the variable terms are the same and the constant terms are different, then the equation has no solutions. So, the constant terms are different. This means the equation has no solutions if the variable terms are the same.

## What is the answer to 5+5+5=550?

The equation 5+5+5=550 is a riddle where the directions are to make the equation true by adding only one single line. The answer is to change the equation from 5+5+5=550 to 545+5=550 or 5+545=550. This is a very simple riddle because the plus sign just has to be reworked into a 4 to make the solution work.

**What should be added to a 5% acid solution to obtain 95L?**

Pure acid is to be added to a 5% acid solution to obtain 95 L of 58% solution. What amounts of each should be used? What type of molecules can dissolve in polar liquids?

### What is the volume of a 500 mL solution?

A 0.5 M solution, with a volume of 500 mL, is diluted to a volume of 1 liter. Calculate the number of moles of solute. How do you calculate percent weight per volume (w/v%)?

### How many liters of Ca(NO3)2 are required to prepare the described solution?

A student is instructed to make 0.250 liters of a 0.200 M aqueous solution of Ca (NO3)2. In order to prepare the described solution in the laboratory, two quantities must be measured accurately.
