Help me this is hard

Following PEMDAS is crucial to solving these. Please Excuse My Dear Aunt Sally

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

Multiplication/Division and Addition/Subtraction are interchangeable.

Now then, number 1 has the following:

$4-2*409-8*96$

There are no parenthesis or exponents, but there is multiplication, so we will start with multiplying. There are two multiplication expressions in the problem.

$-2 * 409 = -818$

$-8 * 96 = -768$

Since you did that, your answer has been simplified to:

$4-818-768$

Now, all you have to do is combine your like terms. Since every term is alike, you can combine the whole expression.

$4-818-768 = -1582$

So, your final answer would be:

$4-2*409-8*96 = -1582$

Hopefully with this information, you can solve the rest. If you have any questions, let me know.

Which set of values could be from a direct proportion

mr Goodwill [35]

Answer:

First table

Step-by-step explanation:

We have to find the set of value which could be from a direct proportion.

We know that

Direct proportion :

When x is directly proportional to y

$x\propto y$

$x=ky$

Where k=Proportionality constant

$k=\frac{x}{y}$

K remain constant when x and y are in direct proportion

From first table

$k=\frac{\frac{1}{2}}{6}=\frac{1}{12}$

$k=\frac{1}{12}$

$k=\frac{2}{24}=\frac{1}{12}$

$K=\frac{3}{36}=\frac{1}{12}$

When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.

From second table

$k=\frac{0}{0}=$ not ]define

$k=\frac{1}{1}=1$

It is not direct proportion because k does not remain constant.

From third table

$k=\frac{0}{2}=0$

$k=\frac{2}{4}=\frac{1}{2}$

It is not direct proportion because k does not remain constant.

Write 0.05 as a fraction. A) 1 12 B) 1 15 Eliminate C) 1 18 D) 1 9

zheka24 [161]

$x=0.0\overline{5}\\\\x=0.0555...\qquad\text{multiply both sides by 10}\\\\10x=0.555...\qquad\text{multiply both sides by 10}\\\\100x=5.555...\\\\\text{Make the difference:}\\\\100x-10x=5.555...-0.555...\\\\90x=5\qquad\text{divide both sides by 90}\\\\x=\dfrac{5}{90}\\\\x=\dfrac{5:5}{90:5}\\\\x=\dfrac{1}{18}\\\\Answer:\ \boxed{0.0\overline{5}=\dfrac{1}{18}}\to\boxed{C)}$
