Answer:
Jeremy is correct
Step-by-step explanation:
Marcus and Jeremy both evaluated the expression −5^2 + 3. Marcus said the answer was −22. Jeremy said the answer was 28. Who is correct? Explain the error in the other student's work.
Marcus is wrong
This is because, Marcus calculated:
-5^2 + 3
= -25 + 3
= -22
This is wrong because it did not follow the rules which states that:
- × - = +
Jeremy calculation is shown below:
-5^2 + 3
-5 × -5 + 3
= 25 + 3
= 28
Jeremy is correct
The Comfy blanket is regularly priced at $39.99 online on amazon. The website is offering a 10% discount as part of their holiday sales. There is a 6% tax as well. Find the find the final cost.
Answer:
$38.4Step-by-step explanation:
Step one:
we are told that the price online is $39.99
and that the discount is 10%
and also tax is 6%
Step two:
discount
let us solve for the deduction first
=10/100*39.99
=$3.99
Tax
=6/100*39.99
=$2.4
The final cost= cost online-10% discount+6% tax
Final cost= 39.99-3.99+2.4
Final cost = $38.4

For which equation is a = 4 not the solution?
9 a = 36
5 a = 54
8 a = 32
6 a = 24
9x4=36 X
8x4=32 X
6x4=24 X
5x4=20, not 54.
So 5xA=54 is the correct answer

Zack wants to purchase vinyl to go on his bathroom floor. The vinyl is sold by the foot in length. If the area of his bathroom is 100 square feet, what will one side of the square bathroom measure?
Answer:
x = 10 feet
Step-by-step explanation:
Given that,
The area of his bathroom is 100 square feet.
We need to find the one side of the square bathroom.
Let the side be x. The area of a square is given by :
[tex]A=x^2\\\\100=x^2\\\\x=10\ \text{feet}[/tex]
So, the side of the square bathroom is 10 feet.
is 12x+6y=18 parallel or perpendicular to 9x-3y=4
Answer:

What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
here, we have,
from the diagram, we get,
m∠TUX = 122°
∴m∠VUS = 122°
(vertically opposite angles are equal)
Hence, The solution is, m∠VUS = 122.

James runs 8 laps in 14 minutes. How many laps can he run in one hour and ten minutes?
Answer: Don't come at me if I'm wrong, but I believe it's 40 laps.
Step-by-step explanation:
First, you need to figure out how many laps James runs in 1 minute and you can do this by dividing the number of laps and minutes (8 laps/14 minutes). This should give you 4/7 laps/minute.
Next, you figure out how many minutes 1 hour and 10 minutes is (just to make things easier) 1 hour and 10 minutes = 70 minutes
Then, you multiple 4/7 and 70 and you get 40 laps.
Answer:
40 laps
Step-by-step explanation:
I just put this into a proportion
so basically i just did 8/14 = ?/70
Then i just worked it like any other problem
8 x 70 then divide 14 and i got 40.
so James ran 40 laps in one hour and tens minutes
NOTE that i turned one hour and ten minutes into minutes

However, the recipe she has only makes a dozen cookies. If the original recipe calls for 1 1/4 cups of sugar, how many cups of sugar does she need to make the cookies for her party? Express your answer as a mixed number.
Given :
Sugar required for 2 1/2 = 5/2 dozen of cookies is 1 1/4 = 5/4 cups.
To Find :
How many cups of sugar does she need to make the cookies for her party.
Solution :
Let, cups of sugar required to make cookies for her party is x.
So,
[tex]x = \dfrac{\dfrac{5}{4}}{\dfrac{5}{2}}\\\\\\x = \dfrac{1}{2}[/tex]
Therefore, 1/2 cup of cookies is required to make 1 dozen cookies.
Hence, this is the required solution.
Answer: 25/8
Step-by-step explanation:
We would first turn 2 1/2 and 1 1/4 into an improper fraction.
That leaves us with 5/2 and 5/4.
Then, because she needs to make 5/2 dozen cookies and needs 5/4 cups of sugar for every batch, we would multiply 5/2 and 5/4 together.
Therefore x, or the amount of sugar she needs, is 25/8
3x + 7 <= 8x - 3

the diagram shows triangle ABD and triangle BCD ABC is a straight line BCD is a quadrilateral triangle angles DAB=25 degrees work out the size of the triangle marked x give a reason for ur answer
Answer:
25
Step-by-step explanation:
First step is to imagine a line that comes straight down from angle b.
This forms a 90 angle AND perfectly bisects angle b.
A triangle has 180 degrees and the angles we currently know are 25 and 90. add those two together and you get 115.
Subtract that from 180 and you get 65 for one part of angle b.
Since the line perfectly bisects angle b, the other side is also 65.
Now, we have the entire triangle DAB.
Angle B is 65x2=130
Angle A is 25
180 degrees in a triangle
130+25=155 degree that we know.
180-155=25 degrees
Which option correctly shows how this formula can be rearranged to isolate x^2?
Options in picture.
Answer:
A
Step-by-step explanation:
We have:
[tex]\displaystyle m=\frac{x_1-x_2}{y_1-y_2}[/tex]
And we want to isolate x₂.
So, let’s first remove the denominator by multiplying both sides by it:
[tex]\displaystyle m(y_1-y_2)=\frac{x_1-x_2}{y_1-y_2}(y_1-y_2)[/tex]
The right side will cancel. This will leave:
[tex]\displaystyle m(y_1-y_2)=x_1-x_2[/tex]
Now, we can subtract x₁ from both sides. So:
[tex]\displaystyle m(y_1-y_2)-x_1=-x_2[/tex]
Finally, we will multiply both sides by -1. So:
[tex]\displaystyle x_2=-m(y_1-y_2)+x_1[/tex]
Hence, our answer is A.
