Estimate 843/84 by first rounding each number so that it has only 1 nonzero digit
mezya [45]

Answer:

10 is your answer.

Step-by-step explanation:

Both 843 and 84 will be turned to 800/80 because 4 is below 5 so it will be turned into a zero and the 8 left an 8.

800/80=10 is your answer.

Solve using substitution for x and y 5x+y=16 <br> y=2-3x
valentina_108 [34]

Answer:

X = 7   Y = -19

Step-by-step explanation:

If you want to solve this equation by substitution then you have to put the second equation in, so it will look something like this

5x + 1(2-3x)=16

Apply distributive property to solve.

Once you find x, plug it in to find y

To double check your work, you can plug the coordinated values back in

-19 = 2 - 3(7)

-19 = 2-21

This is true, so our solution is correct.

Hope this helps :)
