Priya is simplifying the expression $$ Her work is shown to the left. Priya's work is incorrect. Explain the error she made
Answers
Step-by-step explanation:
P.S - The exact question is -
Given - Priya is simplifying the expression -2(4 - 2x) - 3 - 2x Her work is shown to the left.
To find - Priya's work is incorrect. Explain the error she made.
Proof -
Priya simplified the problem as follows :
-2( 4 - 2x ) - 3 - 2x
-8 - 2x - 3 - 2x
-11 - 4x
But the simplification has to be like
-2( 4 - 2x ) - 3 - 2x
⇒-2(4) - 2(-2x) - 3 - 2x
⇒-8 + 4x - 3 - 2x
⇒-8 - 3 + 4x - 2x
⇒-11 + 2x
So, Priya made an error in the second line.
In the second line it has to be -8 + 4x - 3 - 2x but Priya has written -8 - 2x - 3 - 2x.

Answer:
filled in dot on -2 and shade the rest to the right (see below)
Step-by-step explanation:
This can also be read as "x is equal to or greater than -2." The "alligator" mouth, aka the inequality sign, is "eating" the x, meaning it's greater than the -2.
First graph the -2. Because it's also equal to, the dot on the -2 is filled in.
The inequality also acts as an arrow. It's pointing to the right, so the rest of the number line to the right is shaded.
This arrow method works only when the variable is on the left side so that is read "x is greater/less than a number."
Can y’all put this from greatest to least?

ū= (5,8)
Find the direction angle of ū.
Enter your answer as an angle in degrees between 0 and 360° rounded to the nearest hundredth.
Answers
Assuming the angle made by a vector refers to the angle it makes with the positive horizontal axis, take the dot product of u with the vector (1, 0), and recall that
a • b = ||a|| ||b|| cos(θ)
where θ is the angle made by the vectors a and b. Then
u • (1, 0) = ||u|| ||(1, 0)|| cos(θ)
We have
u • (1, 0) = 5×1 + 8×0 = 5
||u|| = √(5² + 8²) = √89
||(1, 0)|| = √(1² + 0²) = √1 = 1
so that
5 = √89 cos(θ)
cos(θ) = 5 / √89
θ = arccos(5 / √89) ≈ 57.99°

336 cm^2
Step-by-step explanation:
Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.
The next one the 6X13 one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.
Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get

Molly's family traveled 5/8 of the distance to her uncle's house on Saturday. They traveled 1/3 of the remaining distance on Sunday. What fraction of the total distance to her uncle's house was traveled on Sunday?
Answers
Answer: [tex]\dfrac{1}{8}[/tex]
Step-by-step explanation:
Given
On Saturday, Molly's family traveled [tex]\frac{5}{8}[/tex] of the total distance
On Sunday, they traveled one-third of the remaining distance.
Suppose the total distance is x
Distance traveled on Saturday is [tex]\dfrac{5x}{8}[/tex]
Remaining distance is
[tex]x-\dfrac{5x}{8}=\dfrac{3x}{8}[/tex]
On Sunday, they travel
[tex]\dfrac{1}{3}\times \dfrac{3x}{8}=\dfrac{x}{8}[/tex]
fraction of total distance traveled on Sunday is [tex]\dfrac{1}{8}[/tex]

A ball inside of a cube has a volume of 524 cubic inches. If each side of the cube measures 12.75 inches. what is the volume of air inside the cube? (Round to the nearest tenth.)
1) 1548.7 cubic inches
2) 2072.7 cubic inches
3) 2596.7 cubic inches
4) 1048.0 cubic inches
Answers
Answer:
1548.7 in³
Step-by-step explanation:
Given that :
Volume of ball = 524 in³
Volume of a cube = s³
Where, s = 12.75 inches
Volume of cube = 12.75 * 12.75 * 12.75 = 2072.671875 in³
The volume of air inside the cube :
(volume of cube - volume of ball)
(2072.671875 - 524) in³
= 1548.671875 in³
= 1548.7 in³ (nearest tenth)

to give them the same denominator,
multiply 3 by (x+2) and 1 by (5x)
3(x+2) = 3x+2 and 1(5x)= 5x
now we have
3x+6/(5x)(x+2) and 5x/(5x)(x+2)
adding the numerators gives us
8x+6/(5x)(x+2)
therefore a=8 and b=6
The value of a and b are a=8 and b=6 respectively.
What is factorization?factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.
We are given the expression as
3/(5x) + 1/(x+2)
We have to multiply 3 by (x+2) and 1 by (5x)
3(x+2) = 3x+2 and 1(5x)= 5x
Now we have
3x+6/(5x)(x+2)
5x/(5x)(x+2)
Now adding the numerators gives us
8x+6/(5x)(x+2)
Therefore a=8 and b=6
