Which expressionis equal to (-7x+5.1y)-(-9x+5.3y)
Furkat [3]

Answer:

The simplified expression for the given expression will be:

c. 2x-0.2y

Step-by-step explanation:

Given expression:

(-7x+5.1y)-(-9x+5.3y)

To simplify the expression.

Solution:

In order to simplify the expression, we will first remove the parenthesis by reversing the signs of the terms inside the parenthesis which lies after a negative sign out side the parenthesis.

<em>This is because negative multiplies to a negative to give a positive and negative multiplies to a positive to give a negative.</em>

So, we have:

⇒ -7x+5.1y+9x-5.3y

Combining like terms

⇒ -7x+9x+5.1y-5.3y

<em>The like terms can be evaluated as</em>

-7x+9x=2x

5.1y-5.3y=-0.2y

Thus, the simplified expression will be:

⇒  2x-0.2y

Given a bag of 5 blue, 3 green, and 8 red marbles.. What is the probability of picking a blue
Anvisha [2.4K]

b = 5, \: g = 3, \: r = 8

total = 5 + 3 + 8 = 16

p(b) =  \frac{5}{16}

p(g |without \: replacement|) =  \frac{3}{16 - 1}  =  \frac{3}{15}  =  \frac{1}{5}  \\

p(b \: and \: g) =  \frac{5}{16}  \times  \frac{1}{5}  =  \frac{1}{16}
