Which facts could be applied to simplify this expression? Check all that apply. (-5x-3y)-(-x-3z).
Mademuasel [1]

Answer:

The correct options are 1, 2, 4 and 6.

Step-by-step explanation:

The given expression is

(-5x-3y)-(-x-3z)

To subtract like term subtract like terms, subtract the coefficients, not the variables.

Therefore option 1 is correct.

Like terms are terms that contain the same variable, raised to the same power. For example: 3xy and 5xy, 4x² and 3x².

Therefore, option 2 is correct.

Using distributive property we get

-5x-3y-(-x)-(-3z)

-5x-3y+x+3z

Only combine terms which contain the same variable.

Therefore option 4 is correct.

(-5x+x)-3y+3z

-4x-3y+3z

The simplified expression is -4x-3y+3z. Therefore option 6 is correct.

Paladinen [302]

Answer:

Hi there!

Your answer is:

Small number = 20

Larger number = 77

Step-by-step explanation:

larger= 4s-3

smaller = s

s+ 4s-3 = 97

5s-3 = 97

+3

5s = 100

/5

s= 20

large number = 4(20)-3

80-3

larger = 77

Double check work!

20+77= 97✓

Hope this helps!
