Step-by-step explanation:
Solve 2 x (4 x 3) = 24
Solve the other values to find one equivalent.
A. 2 + (4 + 3) = 9
B. 2 x (6 x 4) = 48
C. (2 x 4) x 3 = 24
D. 8 = 8

A store marks up a laptop 150% from its original price of $299. There is a sale for 25% off all items in the store. What is the sale price for the computer?
Answers
Answer:
B. 336. 38
Step-by-step explanation:
So, what you want to do is multiply the original price ($299) by the first markup percentage (150%)
299*1.50= $448.50
that is your markup price!
then you have to do the sale % (25%)
so you'll multiply your (25%) by your new price ($448.50)
448.50*.25= $112. 125
THIS IS NOT YOUR ANSWER!
don't forget that!
you will then subtract the sale price ($112.125) by the upcharged price ($448.50)
448.50-112.125= 336. 375
Round up then there is your answer!
= $336. 38
hope this helps!!

3/4 (12x+8)=-13- (2x+3)
Answers
Answer: = − 2
Step-by-step explanation:
3/4 (12x+8)=−13−2x−3
Simplify 3/4(12x+8) to 3(12x+8)/4.
3(12x+8)/4=-13-2x-3
Factor out the common term 4.
3x4(3x+2)/4=-13-2x-3
Simplify 3×4(3x+2) to 12(3x+2).
12(3x+2)/4=-13-2x-3
Simplify 12(3x+2)/4 to 3(3x+2)
3(3x+2)=−13−2x−3
Simplify −13−2x−3 to −2x−16
3(3x+2)=−2x−16
Expand
9x+6=−2x−16
Add 2x to both sides.
9x+6+2x=−16
Simplify 9x+6+2x to 11x+6.
11x+6=−16
Subtract 6 from both sides.
11x=−16−6
Simplify −16−6 to −22
11x=−22
Divide both sides by 11.
x=− 22/11
Simplify 22/11 to 2.
x=−2

The equation C(l) = l3 – l2 + l + 2.5 models the cost to mail a package as a function of its length. To the nearest quarter inch, approximately what is the length of a package that costs $11.00 to mail? Enter your answer as a decimal.
Answers
Answer:
2.25
Step-by-step explanation:
Given the cost model:
C(l) = l3 – l2 + l + 2.5
l = Length fo package
The length of a package that cost $11.00
11 = l³ - l² + l + 2.5
From the table given :
Length of mail which cost $11 will just be slightly greater Than 2 as the cost of 2 length mail cost 8.50
Taking l as 2.20
2.2^3 - 2.2^2 + 2.2 + 2.50 = 10.508
Taking a slightly higher value :
Put l = 2.25
2.25^3 - 2.25^2 + 2.25 + 2.50 = 11.078
Ww can conclude that the length of mail would be 2.25

Answer: 8.856cm
Step-by-step explanation:
To solve the question, we will use the formula:
Sin 41° = opposite / hypothenuse

0.656 = AB / 13.5
Cross. Multiply
AB = 13.5 × 0.656

Which graph represents the function f(x) = 4x
Answers
Answer:
[tex]\boxed{\textsf{ The required graph of y = 4x will be a straight line passing through the origin . }}[/tex]
Step-by-step explanation:
Here we need to plot the graph for the function given to us . The function is ,
[tex]\sf \implies f(x)= 4x [/tex]
In order to plot a graph let us assume that ,
[tex]\sf\implies y = f(x) [/tex]
Hence we now get , that ,
[tex]\sf\implies y = 4x [/tex]
Now let's find out some values of x and y taking which we will plot the graph .
• So , firstly let , x = 0 then y will be equal to 4*0 = 0 . Hence we got one coordinates as (0,0) .
• Secondly let x = 1 , then y will be equal to 4*1 = 4 . Hence we get the third coordinate as (4,0) .
• Thirdly let us take that x = 0.5 then y will be equal to 4*0.5 = 2 . Hence we got the third coordinate as ( 0.5 , 2 )
• Fourthly let x = -0.5 then y will be equal to 4*-0.5 = -2 . Hence the fourth coordinate will be (-0.5 , -2)
Now when we plot it's graph taking suitable scale then it will look something like that as shown in attachment .
For the graph of y = 4x kindly refer to the attachment :) .

10. Write an expression in simplified form to
represent the area of the trapezoid.
Answers
Answer:
48[tex]x^{7}[/tex]y
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases , then
A = [tex]\frac{1}{2}[/tex] × 4[tex]x^{5}[/tex] × (9x²y + 15x²y )
= 2[tex]x^{5}[/tex] × 24x²y
= 48[tex]x^{7}[/tex]y
The simplified expression for the area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].
What is trapezium?A trapezium is a quadrilateral with four sides where two sides are parallel to each other.
We have,
Trapezium.
Height = 4[tex]x^5[/tex]
Parallel sides are 15x²y and 9x²y.
The area of the trapezium.
= 1/2 x h x ( sum of the parallel sides )
Now,
Area of the trapezium.
= 1/2 x 4[tex]x^5[/tex] x (15x²y + 9x²y)
= 2[tex]x^5[/tex] x (15x²y + 9x²y)
= 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex]
Thus,
The area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].

Two groups are hiking at about the same speed . Mario’s group hikes for 2.5 hours Seemas group hikes for 4.7 hours and covers 8.8 more miles . How fast are the kickers going ? Solve the equation below to find out . 4.7x=2.5x+8.8
Answers
Answer: 18.8 miles
Step-by-step explanation:
Ww are given the equation 4.7x=2.5x+8.8 to solve the question. This will be:
4.7x = 2.5x + 8.8
