Yes you did, you count up all the decimal spaces in all (which is 4 in this case) and put that amount of decimal spaces in the product.

Yes you did, because you have to move the decimal the number of places added together (How many decimal places?) 0.14 and 0.77 is 4 decimal places, so you move it 4 times to the right at the final product. Hope I helped!

What is the result of adding these two equations? \begin{aligned} 2x+3y &amp;= -5 \\\\ 5x-y &amp;= -12 \end{aligned} 2x+3y 5x−y
EleoNora [17]

Answer:

7x+2y = -17

Step-by-step explanation:

We have the following equations:

2x+3y = -5

5x-y = -12

If we want to add these equations, we just need to add x-terms, y-terms and independent terms.

(2x+5x)+(3y-y) = -5-12

7x+2y = -17

I hope it helps you!

It is 4:12 p.m. Emma's mom will be home from work in 70 minutes, and Emma has gymnastics lessons at 6:00 p.m. How much time will
Mademuasel [1]
We know that her mom will be home in 70 minutes and if its 4:12 then that means that her mom will be home at 5:22 because 70 minutes is 10 minutes more than an hour. If her gymnastics lessons are at 6:00 then she has 38 minutes in-between the time her mom gets home and her gymnastics lesson.

Hope this helped!
