3 ( g + 5 ) − 3 ( g + 6 ) =

3g + 15 - 3g - 18

The numbers before the parentheses are multiplied by numbers Inside parentheses

And :

3g - 3g -18 + 15= - 3

3g - 3g are symmetrical and destroy each other

- 3

distribute each bracket, multiplying the terms in the bracket by the value outside the bracket.

= 3g + 15 - 3g - 18 → ( collect like terms)

=(3g - 3g) + (15 - 18) = 0 + ( - 3) = - 3

Joanna joins a CD club. She pays $7 per month plus $10 for each CD that she orders. Write an inequality to find how many CDs she

Effectus [21]

Lets use x as the number of CD's that she will buy in a month. So knowing that, our inequality can look like this. 7 + 10x < or = 100. Why? because we will have to multiply 10 with the number of CDs she will purchase in a month to get the total she spends. Hence 10 times x. She also has to add a 7 membership fee per month to this. Also, she has to remember that what she paid has to be less or equal to 100 because the problem states that she spends no more than 100 a month.

Each page of a top-secret report on aliens requires 2 \text{ KB}2 KB2, start text, space, K, B, end text of space in digital for

fredd [130]

The maximum number of pages the report can have, using scientific notation, is of:

2 x 10^6.

<h3>What is scientific notation?</h3>

A number in scientific notation is written as follows:

$a \times 10^b$

With the base symbolized $a \in [1, 10)$ , meaning that it can assume values from 1 to 10, with an open interval at 10 meaning that for 10 the number is written as 10 = 1 x 10¹, meaning that the base is 1.

For this problem, the maximum number of pages that the report can have is given by the following division:

Maximum number of pages = Total capacity/Size of page.

These variables, from the text, are given as follows:

Total capacity: 4 x 10^6 KB.

Size of a page: 2 KB / page.

Hence the number of pages is obtained as follows:

Maximum number of pages = 4 x 10^6 KB / (2 KB/ page) = 2 x 10^6 pages.

When two numbers are divided in scientific notation, the bases are divided(4/2 = 2), while the exponents are subtracted (6 - 0 = 6).

Alex determines that there are 5 chocolate candies per cubic inch. If there are 150 chocolate candies in a jar, what is the volu

AlekseyPX

The answer is 30 cubic inches.

If <span>5 chocolate candies are in 1 cubic inch, 150 </span><span>chocolate candies will be in x cubic inches:
</span>5 chocolate candies : 1 cubic inch = 150 chocolate candies : x<span> cubic inches
</span>5 : 1 = 150 : x
5 = 150 : x
x = 150 : 5
x = 30

So, if <span>150 chocolate candies are in a jar, the volume of the jar is 30 cubic inches.</span>
