Aimee went to a stationary shop. She purchased 2 packs of red pens, 4 packs of black pens, and 3 packs of blue pens.
The cost of each pack of pens was $2.50. Which expression shows the total amount Aimee spent on the pens?
A ($2.50 x 2 x 4x3)
B $2.50 x (2+4+3)
C($2.50 x 2) + 3+4
D (52.50 +2 +4+3)
Answer:
A.
Step-by-step explanation:
The answer is B.
Each pack costs 2.50, so this means we can add all of our packs brought together, before multiplying. (2+4+3)=7. So our final equation should be 7 x 2.50 ,therefore B is our correct answer.

George practises his guitar for 1 1/5 hours per day on school days. On Saturday he increases to 2 1/2 times his normal time. How many hours does he practice on Saturdays.
Answer: 231/10
Step-by-step explanation: 11/5 x 21/2
= (11 x 21) = 231
= 231/5 x 2
= 231/10
Answer:
3 hours
Step-by-step explanation
It would be easier to convert your fractions into decimals.
1/5 is the same as 2/10. Since the denominator was multiplied by 2 then the numerator must be multiplied by 2 also.
2/10 in decimal form is 0.2
He would practice 1.2 hours per day on school days
On Saturday his practice is 2 1/2 times longer than 1.2 hours.
Convert 1/2 into decimal form. 1/2 is the same as 0.5.
So 2 1/2 is the same as 2.5
If you multiply the original time (1.2 hours) by 2.5, you'll know how long he practices on Saturday.
1.2 x 2.5 = 3 hours.
1.2
x 2.5

since you have 1 decimal place in the top number and 1 decimal in the bottom number, you must move your decimal 2 places to the left on your answer. Instead of 300, your answer becomes 3.00

What is the value of x in the equation 3x/4=24
Answer:
X= 32
Step-by-step explanation:
Answer:
X = 32
Step-by-step explanation:
If you do 24 x 4 you will get 96.
From there you have to divide 3 by 96, since 3 times x has to equal to 96. Since 24 x 4 is 96 and you need to divide 3x by 4.
After you do 96/3 you will get 32. Thus the answer being 32.

Answer:
[tex]x = 88[/tex]
Step-by-step explanation:
the degrees of a triangle = 180. write an equation adding the angle measures given
[tex]48 + x - 44 + x = 180[/tex]
collect like terms on the left

The area of a rectangle garden is 4158m^2. If the width of the garden is 54m, what is its length?
Answer:
Step-by-step explanation:314
Answer:
length-77m
Step-by-step explanation:
since we already know the area which is 4158m² and width which is 54m we will do the opposite of multiplication to find the length which is division you divide 4158 by 58 and we get 77m

Luisa is saving money to buy a new laptop computer that costs $460 . She started with $110 and every month she saves $25 . Her savings can be modeled by the function s (x) =25x+110
A : graph the equation below make sure you label each axis with the appropriate unit of measure
B. Write a statement using function notation that shows when Luisa will reach her goal
C: use words to describe the symbolic statement
Can you guys please help me I’ll mark you as a brainliest . Please help just this question please
Answer:
A: *Graph shown in image*
B: She will reach her goal when the x is 14 (14,460) with y being 460 (or the goal) giving you the equation [tex]y = \frac{50}{2} x + 110[/tex] going up 50 and going right 2 with x being 7 meaning you would have to go up 50 and right 2, seven times to reach 460.
Step-by-step explanation:
A: From your previous question you asked 14 hours ago with a screenshot, you did your graph wrong so for YOU make your graph look like the second image. (Plot the point 0,110 for the y intercept and plot -4.4,0 for the x line)
B: Lot's of explaining but you will get it once you add it to your own graph and go with the flow. Kind of like slope intercept form.
For C: you can answer in your own words since I gave you the priority answer(s)

Describe the decimal multiplication equation and product shown by the model. Include details of where each part of the equation is found on the model.
The question is an illustration of multiplication model.
The multiplication model is: [tex]\mathbf{0.90 \times 0.10 =0.09}[/tex]
From the figure, the shaded portions are:
[tex]\mathbf{Green = \frac{90}{100}}[/tex]
[tex]\mathbf{Orange = \frac{10}{100}}[/tex]
So, the multiplication model represents:
[tex]\mathbf{Model =Green \times Orange}[/tex]
This gives
[tex]\mathbf{Model =\frac{90}{100} \times \frac{10}{100}}[/tex]
Express as decimal
[tex]\mathbf{Model =0.90 \times 0.10}[/tex]
[tex]\mathbf{Model =0.09}[/tex]
Hence, the multiplication model is:
[tex]\mathbf{0.90 \times 0.10 =0.09}[/tex]

Cannot be determined
Answer:

Step-by-step explanation:
the A point is in line with 10 squared and its in line with the 17 squared
The measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.
What is a rotation transformation?A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.
For the given situation,
The graph shows the triangle CAT.
If a rotation takes triangle CAT to C'A'T',
then from the definition of rotation transformation the size and shape of the figure stays exactly the same.
Thus the measure of C'T' is same as CT.

The ratio of the number of apples to the number of oranges is 5:2 . There are 18 more apples than oranges. If 24 oranges are added, what will be the new ratios of apples to the numbers of orange?
Answer:
5 : 6
Step-by-step explanation:
The ratio of apples to oranges is 5 : 2 = 5x : 2x ( x is a multiplier )
There are 18 more apples than oranges , that is
5x = 2x + 18 ( subtract 2x from both sides )
3x = 18 ( divide both sides by 3 )
x = 6
There are 5 × 6 = 30 apples and 2 × 6 = 12 oranges
The number of oranges is increased by 24, to 12 + 24 = 36 , then
30 apples : 36 oranges ( divide both parts by 6 )
= 5 : 6

To solve this problem, we will need to use trigonometry.
Remember: SOH-CAH-TOA
Looking from the angle, we know the opposite side and want to find the adjacent side. Therefore, we should use the tangent function.
tan(15) = 5 / x
x * tan(15) = 5
x = 5 / tan(15)
