-3(5)^2-(-2)(-8) simplify

Mathematics
1 answer:
avanturin [10]4 years ago
3 0

To do this, we're going to use the order of operations (PEMDAS):

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

First let's do parentheses, there isn't anythig in parentheses we need to simplify, so we can skip this step.

Next let's look for exponents. I see we have a 5^2 so let's replace that with 5^2=25:

-3(25)-(-2)(-8)

Now let's look for multiplcation. We know that things that are right next to eachother in parentheses represent multiplcation, so let's simply this more:

-3(25)=-75

(-2)(-8)=16

-75-16

And now we're left with a simple problem we know how to solve.

Answer: -91

Hope this helps!

y  - 9 =  \frac{1}{5} (x - 2) \\

y - 9 =  \frac{1}{5} x -  \frac{2}{5}  \\

Add sides 9

y -9 + 9 =  \frac{1}{5} x - 0.4 + 9 \\

y =  \frac{1}{5} x + 8.6 \\

y =  \frac{1}{5} x +  \frac{43}{5}  \\

This is the slope-intercept form.

<h2><u>Remember from now on</u> ,</h2>

The coefficient of x is the slope of the line in slope-intercept form of the linear functions.

Thus ,

Slope = 1 / 5

And the correct answer is (( D )) .

Simplify 12cm to 2.5mm
julia-pushkina [17]

Given:

12cm to 2.5mm

To find:

The simplified for of given statement.

Solution:

We know that,

1 cm = 10 mm

12 cm =120mm

We have,

12cm to 2.5mm

It can be written as

\dfrac{12\ cm}{2.5\ mm}=\dfrac{120\ mm}{2.5 mm}

\dfrac{12\ cm}{2.5\ mm}=\dfrac{120}{2.5}

\dfrac{12\ cm}{2.5\ mm}=48

Therefore, the value of 12 cm to 2.5 mm is 48 or 48:1.
