I NEED HELP!!!!! ASAP!!!!!
Answer: 127 11/12
Step-by-step explanation:
1. 1/2 + 3/4 = 2/3
Change 1/2 by by multiplying by 2 to get a common denominator of fourths.
2/4 + 3/4 = 2/3?
5/4 = 2/3?
no
2. 5/8 - 1/4
Change 1/4 by by multiplying by 2 to get a common denominator of eighths.
5/8 - 2/8 = 3/8?
3/8 = 3/8 ?
yes
3/8 x 10 = 30/8
3. 4/5 +7/10 = 1 1/2
Change 4/5 by multiplying by 2 to get a common denominator tenths.
8/10 + 7/10 = 1 1/2?
15 /10 = 1 1/2?
yes
1 1/2 x 10 = 25
4. 2 1/3 - 1 5/6 = 1/6
Change 1/3 by multiplying by 2 to get a common denominator sixths.

Matthew is going to shop rite with $15.He brought a package of croissants for $1.99.The cost of a box of Digiorno pizza is $4.00. What is the maximum number of digiorno pizzas can he buy?
Answer:
he would only be able to buy 2 boxes of pizza
Step-by-step explanation:
Subtract $1.99 from the $15 he has.
$15 - $1.99 = $13.01
Divide $13.01 by $4.00
$13.01/$4.00 = 3.25
There is a decimal in the final answer which means its not a whole pizza. So, the max he would be able to buy is 2 bokes of pizza

[5 2 1]
Answer:
Step-by-step explanation:
For the multiplication of two matrices, number of columns in 1st matrix should be equal to the number of rows of the 2nd matrix.
In the given question,
1st matrix → [tex]\begin{bmatrix}2 & 8 & 1\\ 0 & 5 & -2\end{bmatrix}[/tex]
Number of columns in this matrix = 3
2nd matrix → [5 2 1]
Number of rows in this matrix = 1
Therefore, number of columns in 1st matrix are not equal to the number of rows in the 2nd matrix.
Therefore, multiplication of matrices given in the picture is "Impossible".

Answer:
1,3,4, and 7 will all have 42 degrees and 2,5,6 will have angles of 138 degrees
Step-by-step explanation:
since one side of a circle is always 180 degrees, you would need to subtract 180 from 138, which would give you 42 degrees, and because every angle corolates with another angle in this situation it would mean any that are in the same place either in the first or second set of angles would be the same as the other.
What is |-26|?
(a) -26,
(b) 26,
(c) 0,
(d) 1
Answer:
(b)26
Step-by-step explanation:
Step 1: Isolate the absolute value expression.
Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.
Step 3: Solve for the unknown in both equations.
Step 4: Check your answer analytically or graphically.
how do i solve this??
You are given either the x value or the y value.
Replace the x or y in the equation and solve for the missing values.
-4x + 5y = 3
First you are given x = 0:
So you have -4(0) + 5y = 3
Simplify:
0 + 5y = 3
Divide both sides by 5:
y = 3/5
Next you have x = 1:
-4(1) + 5y = 3
Simplify:
-4 + 5y = 3
Add 4 to both sides:
5y = 7
Divide both sides by 5:
y = 7/5
Third you are given y = 3
-4x + 5(3) = 3
Simplify:
-4x +15 = 3
Subtract 15 from both sides:
-4x = -12
Divide both sides by -4:
x = 3

The measures of the exterior angles of an octagon are x°, 2x°, 4xº, 5x°, 6x°, 8xº,
9x", and 10x°. Find the measure of the smallest exterior angle.
Answer:
8°
Step-by-step explanation:
The sum of the measures of the exterior angles of a any polygon = 360.
So, x + 2x + 4x + 5x + 6x + 8x + 9x + 10x = 360
45x = 360
x = 8°
The measure of the smallest exterior angle would be equal to 8°
What is Octagon ?In geometry, a Octagon is a eight - sided polygon. For a [n] sided polygon -
Sum of interior angles = (n - 2) × 180°Each interior angle of a regular polygon = [(n − 2) × 180°/n]Sum of exterior angles = 360°According to the question, we have - A Octagon and the measures of the exterior angles of an octagon are x°, 2x°, 4x°, 5x°, 6x°, 8x°, 9x° and 10x°.
The sum of the exterior angles of the octagon will be 360°.
Therefore, we can write -
x + 2x + 4x + 5x + 6x + 8x + 9x + 10x = 360°
45x = 360°
x = 360/45
x = 8
The smallest exterior angle would be equal to [x]° = 8°
Therefore, the measure of the smallest exterior angle would be equal to 8°

The price per night for a hotel room is different at three different hotels. Hotel Nights Price (in dollars) A AA 3 33 192 192192 B BB 5 55 300 300300 C CC 7 77 455 455455
Answer:
Hotel B is the least expensive
Step-by-step explanation:
Given
See attachment for clear details
Required
The least expensive
To do this, we simply divide the total cost by the number of nights to get the unit price
i.e.
[tex]Unit = \frac{Price}{Nights}[/tex]
Hotel A
[tex]Nights = 3\\Price= 192[/tex]
[tex]Unit = \frac{192}{3}[/tex]
[tex]Unit = \$64[/tex] per night
Hotel B
[tex]Nights = 5\\Price= 300[/tex]
[tex]Unit = \frac{300}{5}[/tex]
[tex]Unit = \$60[/tex] per night
Hotel C
[tex]Nights = 7\\Price= 455[/tex]
[tex]Unit = \frac{455}{7}[/tex]
[tex]Unit = \$65[/tex] per night
From the calculations above;
Hotel B is the least expensive because 60 is less than 64 and 65
A motorist drives 146km at a certain speed. She then increase this speed of by 19km/hr and take the same time to travel the next 16km. Find her speed for both part of the journey. Pleaseeeeeeeeeeee helpppppppppppp
Step-by-step explanation:
A motorist drives 146km at a certain average speed she then increases the speed by 9km/h and takes the same time to travel the next 164km.
find her speeds for both parts of the journey.
:
let s = his original speed
then
(s+9) = the increased speed
:
Write a time equation; time = dist/speed
146%2Fs = 164%2F%28%28s%2B9%29%29
cross multiply
164s = 146(s+9)
164s = 146s + 1314
164s - 146s = 1314
18s = 1314
s = 1314/18
s = 73 km/h is his original speed

What is the value of x?
Answer:
The value of x=27
Step-by-step explanation:
A certain psychological test measures empathy and emotional intelligence. The score, S, of a randomly selected senior student at a large university has a mean of 123 and a standard deviation of 29. The score, F, of a randomly selected first-year student at a large university has a mean of 104 and a standard deviation of 34.
Suppose we randomly select one senior student and one first-year student.
Calculate the mean of the difference D = S – F.
μD = 17.7482
μD = 19
μD = 44.6878
μD = 227
Answer: The answer is 19
Step-by-step explanation: EDGE2020
The mean of the difference D = S - F is 19, which is the correct option (B).
What is the standard deviation?A standard deviation (σ) is a measure of the distribution of the data in reference to the mean.
To calculate the mean of the difference D = S - F, we need to find the expected value of the difference between two random variables, one representing the scores of senior students and the other representing the scores of first-year students.
Here,
μS = 123
μF = 104
The mean of the difference is the difference of the means, so we have:
μD = μS - μF
μD = 123 - 104
μD = 19
Therefore, the mean of the difference D = S - F is 19.

Answer:
-2x > 30x < -15Step-by-step explanation:
A product is formed by multiplying the factors. Here, you want the product of -2 and x, so that is indicated as ...
-2x
You want that product greater than 30. The symbol for "greater than" is >, so you have ...
-2x > 30 . . . . the desired inequality
__
The most straightforward way to solve this is to divide by the coefficient of x. Because that is negative, you must reverse the inequality symbol from "greater than" to "less than."
x < 30/(-2)
x < -15 . . . . . . the desired solution
_____
Additional comment
It may not be clear why multiplying or dividing an inequality causes the symbol to be reversed. You can think of it as reflecting the inequality over the point x=0 on the number line. Where larger numbers were on the right, they get reflected to points farther left, so as negative numbers, they are smaller numbers.

Raul is cutting boards for a project. He has a board that measures 8 feet and is cutting it into 3/4 foot pieces. How many whole pieces of 3/4 foot will he be able to cut?
Answer:
10
Step-by-step explanation:
1 board = 3/4 foot = 0.75 of a foot
x boards = 8 feet
1/x = 0.75 / 8 feet Cross multiply
0.75 x = 8 Divide both sides by 0.75
x = 8/0.75
x = 10 2/3 boards.
We are told to throw the fractional board away so Raul will get 10 pieces from an 8 foot piece of lumber.
