Question

70+15=85 125+85=210 Write into an equation.​

Answer 1

Brother asked a very good question.

We can write the given arithmetic expressions into equations as follows:

70 + 15 = 85

This can be written as an equation: x + 15 = 85, where x is the unknown value that needs to be determined.

125 + 85 = 210

This can be written as an equation: y + 85 = 210, where y is the unknown value that needs to be determined.

These equations can be used to solve for the unknown values x and y by performing inverse operations (such as subtraction or division) to isolate the unknown variable on one side of the equation.

Answer 2

The equations are simple addition problems: 70 + 15 = 85 and 125 + 85 = 210. For time addition, you add the minutes or seconds together and convert them if they exceed a standard unit threshold.

Step-by-step explanation:

The equations derived from the given math problems are straightforward addition problems. Here's how you can write them into equations:

• 70 + 15 = 85
• 125 + 85 = 210

When adding units of time, the process is similar:

1. 15 minutes + 60 minutes = 75 minutes
2. 10 minutes + 20 minutes = 30 minutes
3. 15 seconds + 45 seconds = 60 seconds

In each case, you are simply adding the numbers together. Conversion may be necessary when the sum crosses a standard unit threshold, such as 60 seconds equaling 1 minute, or 60 minutes equaling 1 hour.

Example of time conversion:

1 hour 25 minutes + 20 minutes + 15 minutes = 1 hour 60 minutes = 2 hours

This is because 60 minutes is equivalent to 1 hour, so you add that to the original hour to get a total of 2 hours.
