Lillian and Isabella went shopping for school supplies. Lillian found her favorite notebook on sale so she bought three of the exact same notebook. Isabella also wanted a notebook. She bought one of the same notebooks that Lillian bought. Both girls started shopping with the same amount of money. If Lillian spent all of her money and Isabella had $5 left, how much money did each girl have when she arrived at the store? please show your work/steps
Answer:
Each girl had $7.50 when they arrived.
Step-by-step explanation:
We have to figure out what c (cost of each notebook) is first before we find out how much money each girl had. We also know they have the same money, so both sides are connected. The equation should be: 3x = x + 5.
3x = x + 5
First, subtract x from both sides. This cancels out the addition by x.
3x - x = 5
Now, subtract x from 3x. This equals 2x.
2x = 5
To cancel out the multiplication by 2, divide both sides by 2.
x = 5/2
Lastly, divide 5 by 2 to get 2.5.
x = 2.5
Substitute x for 2.5 in the earlier equation (3x = x + 5)
3(2.5) = 2.5 + 5
First, multiply 3 by 2.5 to get 7.5.
7.5 = 2.5 + 5
Add 2.5 to 5 to get 7.5.
7.5 = 7.5
Both sides are equal so we have our answer. So, both girls had $7.50 when they arrived at the store.

A 13.5 m fire truck ladder is leaning against a wall.
Find the distance the ladder goes up the wall if it
makes an angle of 43.8° with the ground.
To solve this problem you must apply the proccedure shown below:
1. You have the the 13.5-m fire truck ladder is leaning against a wall and the ladder makes an angle of 39 degrees 45 ' with the horizontal.
2. Then you have:
39 degrees 45'=39.75°
Sin(39.75°)=d/13.5
d=13.5xSin(39.75°)
d=8.63

Draw a model that shows 3 items being divided equally for 4 people. How much will each person have?
Answer:
Each person will get 3 pieces
Step-by-step explanation:
First you separate each item in 4 pieces. Then you get 12 pieces. Since 12 divided with 4 is 3, the answer is 3.
We want to draw a model that shows 3 items being divided equally for 4 people, we will see that each person receives 0.75 of an item.
Drawing the model.Here you just need to create an area that represents 3 elements, then replicate that area but this time with 4 sections, so we can see how much each of the 4 sections takes from the 3 elements.
The model can be seen below. (this is just an example, you should do it with a ruler to have a proper model).
Now to see how much each person haves we just take the quotient:
3/4 = 0.75
Each person receives 0.75 of an item.

A radioactive substance decays at a rate of 3.4% per day. If it starts at 200 grams, how
many days will it take for the substance to decay to less than 150 grams?
Answer: 9
Step-by-step explanation:
Since the percent is decaying, you subtract 3.4 from 100, which gets you 96.6
200(0.966)^9 gets you 146.5 which is less than 150
5. Which equation will solve the following word problem? The professor has 390 books that he wants to display in his office. Each shelf can hold 65 books. How many shelves will he need?
A)390s = 65
b)390(65) = s
c)s/390 = 65
d)390 = 65s
Answer:
[tex]65s = 390[/tex]
Step-by-step explanation:
Given
[tex]Books = 390[/tex]
[tex]Shelf = 65[/tex]
Required
Write an expression for the scenario
1 shelf can hold 65 books.
s shelves can hold 65s books.
So:

Zoey's dog has a water bowl with a diameter of 6 inches. Sam's
dog has a water bowl with a diameter of 10 inches. What is the
approximate difference in the circumference (distance around)
ut of the two water bowls?
Answer:
12.56 inches
Step-by-step explanation:
Circumference: C = 2*pi*r
I will be using 3.14 in place of pi
Divide the diameters by 2, so 3 for Zoey and 5 for Sam
Multiply (2*3.14*3) and (2*3.14*5)
For Zoey you get 18.84 and for Sam you get 31.4
31.4-18.84= 12.56 in difference

i hope this one helps !!
Answer:
20,020 in. on the plans
Step-by-step explanation:
To get from 11 in. to 88 in. (from plans to real life), you multiply by 8.
Therefore, to get from 160,160 to ?? (from real-life to plans), you would divide by 8.
160,160 / 8 = 20,020
To check, you can multiply 20,020 by 8 to go from plans to real-life measurements; 20,020 • 8 = 160,160)

slope of -2 and
crosses the y-axis at 5
in slope-intercept form
Answer:
y = -2x + 5
Step-by-step explanation:
Recall that slope-intercept form is y = mx + b where m is the slope and b is the y intercept
In this case our slope is m = -2
and, line crosses y-axis at 5 which is b = 5
thus, y = -2x + 5

Kate had $140. She spent
2/5 of it. What amount did she spend?
The amount Kate spent $ 56 of the $ 140 she had.
To find out how much Kate spent, we need to calculate 2 / 5 of the total amount she had, which was $ 140.By multiplying fractions we mean the product of a fraction with another number or a fraction. The product of such multiplication could be a fraction or a whole.
To do this, we can multiply $ 140 by the fraction 2 / 5:
= $ 140 * 2 / 5
= $280 / 5
= $ 56
Therefore, Kate spent $ 56 of the $ 140 she had.
