Evaluate: -4(-1/8 + 0.3) a. - 1.7 b. - 0.7 c. 0.8 d. 2

Rewrite decimal to fraction:


Change the denominators to be the same:


Simplify each fraction:


Add the fraction in the bracket:


Multiply:

Hey there! :) 

-4(-1/8 + 0.3)

Simplify this by using the rainbow technique.

(-4 × -1/8) + (-4 × 0.3)

Simplify.

Remember that a negative times a negative is a positive while a positive times a negative is a negative.

(1/2) + (-1.2)

Get rid of parenthesis.

1/2 - 1.2

Change 1.2 into a fraction.

1/2 - 1 2/10

Multiple 1/2 by 5/5 so that both of our fractions have the same denominator.

1/2 · 5/5 = 5/10

So, our new question looks like this :

5/10 - 1 2/10

Change 1 2/10 into an improper fraction.

5/10 - 12/10

Simplify.

-7/10

Change it into a decimal.

-0.7 → b is our final answer :) 

~Hope I helped!~

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
