This is the answer
first you must eliminate the denominator and that you do with multiplication
then eliminate the number that is on the same side of the letter and that you do it by placing the same number but with a different sign and so you have the answer.

also there is the check.

Alecia walked 3/10 of a mile from school,stopped at the grocery store on the way, then walked another 4/10 of a mile home.Georgi

Nutka1998 [239]

Answer:

Alecia lives farther from school

Step-by-step explanation:

<em>Georgia</em>

we know that

The distance from the school to her home is 67/100 of a mile

$\frac{67}{100}=0.67\ miles$

<em>Alecia</em>

we know that

The distance from the school to her home is

3/10 of a mile plus 4/10 of a mile

$\frac{3}{10}+\frac{4}{10}=\frac{7}{10}=0.7\ miles$

Compare the distances

$0.7\ miles>0.67\ miles$

therefore

Alecia lives farther from school

Each bacterium in a petri dish splits into 2 bacteria after one day. The function b(d) = 600 • 24 models

TiliK225 [7]

Answer:

(a)Initial Number of Bacteria=600

(b) $\text{Number of bacteria after 5 days}=19200$

Step-by-step explanation:

Given an initial number $b_0$ of bacteria in a petri dish, and each bacteria splits into 2 bacteria after one day.

The function $b(d) = 600 \cdot 2^d$ models the number of bacteria, b after d days.

Given $b(d) = 600 \cdot 2^d$

When d=0,

The initial number of bacteria in the petri dish,

$b_0=b(0) = 600 \cdot 2^0=600$

After 5 days, when d=5

$b(5) = 600 \cdot 2^5=600 \cdot 32\\\text{Number of bacteria after 5 days}=19200$

7) Staples charges $28 for 8 boxes of pencils and $47 for 4 pencil sharpeners. Ms. Felix orders 70 boxes of pencils and 21 penci

barxatty [35]

Answer:

<u><em>Ms. Felix would spend $491.75 on her order.</em></u>

Step-by-step explanation:

First, let's identify the components of this word problem that we'll need to solve it. We know that Staples charges $28 for 8 boxes of pencils, and $47 for 4 pencil sharpeners. Before we do anything else, we'll find the unit price of the pencils and pencil sharpeners to make it easier for us. Let's begin with the boxes of pencils. 28 ÷ 8 = $3.50 per box of pencils. As for the pencil sharpeners, 47 ÷ 4 = $11.75 per sharpener. Now that we know the basic costs, let's use them to solve our problem at hand. We'll multiply the number of items ordered by the base cost of the item.

Boxes Of Pencils:

70 × $3.50= $245.00

Sharpeners:

21 × $11.75= $246.75

Now that we know the cost of the two seperate items Ms. Felix ordered, let's add them to get our final answer.

Our final answer would be $491.75.
