A teacher writes four numbers on the board as shown blow

She asked the students to form 4-digit number, and subtract from 4310.
Write two possible solutions
Answer:
909 and 3267
Step-by-step explanation:
There are a total of 24 possible combinations using these 4 digits. This means that any one of these combinations subtracted from 4310 would be a possible solution. Therefore, we can create the following 2 combinations (below in bold) and subtract them from 4310 to get two possible solutions...
4310 - 3401 = 909
4310 - 1043 = 3267
Finally, we have two possible solutions which would be 909 and 3267
2 + (-25) =?
NO LINKS OR I WILL REPORT!! 10 POINTS PLEASE ANSWER!
Answer:
-23
Step-by-step explanation:
Answer:
-23
Step-by-step explanation:
When you do positive-negative you subtract the 2 numbers then take the sign of the number that had the highest absolute value.
25-2=23
The absolute value of -25 is 25
(|-25| = 25)
And the absolute value of 2 is 2
(|2| = 2)
25 > 2
So it would be -23

Answer:
The sequence would be arithmetic. This is because an arithmetic sequence has a common number multiplying, adding, subtracting etc. The common rule for this set of numbers was x5. 9x5=45, 45x5=225 etc. We simply used this method with negative numbers, but the rule was still multiplying.

What is the image point of (4, -6) after a translation right 5 units and
up 4 units?
Answer:
Coordinate point of the image is (9, -2)
Step-by-step explanation:
In the coordinate point (4, -6);
=> x-value = 4
=> y-value = -6
We know that the translation of;
=> 5 units right would add 5 to the x-value
(x) + 5 = (4) + 59 <= This is the x-value of the image being created by the translation.=> 4 units up would add 4 to the y-value
(y) + 4 = (-6) + 4-2 <= This is the y-value of the image being created by the translation.Therefore the answer; (x, y) => (9, -2)

A cube is intersected by a plane from the top edge of one face to the bottom edge of the opposite face as shown.
What is the shape of the cross-section?
square
rectangle that is not a square
triangle
parallelogram that is not a rectangle
Answer:
B
Step-by-step explanation:
a rectangle that is not a square
The plane will be rectangular which is not a square. Then the correct option is B.
What is a rectangle?It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
A cube is intersected by a plane from the top edge of one face to the bottom edge of the opposite face as shown.
Let a be the side length of the cube.
The length of the rectangular plane will be
L² = a² + a²
L = a√2
Then the dimension of the plane is 'a' and 'a√2' units.
The plane will be rectangular which is not a square. Then the correct option is B.

A right rectangular prism has a height of 15 meters, a length of 4 meters, and a width of 3 meters. Which expressions
show how to calculate the volume? Check all that apply.
Answer:
180m^3
Step-by-step explanation:
Given data
Height = 15m
Lenght= 4m
Width=3m
We know that the volume of a rectangular prism is expressed as
Volume= L*W*H
Substitute
Volume= 4*3*15
Volume= 180m^3

Step-by-step explanation:
Given
See attachment for floor space
Required
Find x
The floor can be partitioned into three space.
The dimension and the area of each space is:
Dimension: 10 by 10
[tex]A_1 = 10* 10 = 100[/tex]
Dimension: 10 by x
[tex]A_2 = 10* x = 10x[/tex]
Dimension: x by x
[tex]A_3 = x* x=x^2[/tex]
So, the total area is:
[tex]Area =100 +10x + x^2[/tex]
Given that:
[tex]Area = 475[/tex]
So, we have:
[tex]100+10x+x^2 =475[/tex]
Rewrite as:
[tex]x^2 +10x+100-475=0[/tex]
[tex]x^2 +10x-375=0[/tex]
Expand
[tex]x^2 + 25x -15x -375 = 0[/tex]
Factorize
[tex]x(x + 25) -15(x +25) = 0[/tex]
Factor out x + 25
[tex](x+25)(x-15)=0[/tex]
Solve:
[tex]x = -25\ or\ x = 15[/tex]
x cannot be negative; So:

Marco needs to climb up to the roof of his house. He placed his ladder so that the bottom of
the ladder was 4 feet away from the wall. If his ladder was 13 feet long, how high up was the
top of the ladder against the wall of the house? Round your answer to the nearest tenth.
Answer:
12.4 feet
Step-by-step explanation:
A ladder placed against the wall forms a right angle triangle
Hypotenuse ² = opposite ² + adjacent ²
Hypotenuse = 13 feet
Opposite = 4 feet
Adjacent = x
Hypotenuse ² = opposite ² + adjacent ²
13² = 4² + x²
169 = 16 + x²
169 - 16 = x²
153 = x²
Find the square root of both sides
√153 = √x²
12.369316876852 = x
x = 12.4 feet
Adjacent = x = 12.4 feet

Answer:
D. Multiply the second equation by 3. The solution is x = 12, y = 10
Step-by-step explanation:
Given:
x + 3y = 42 (first equation)
2x - y = 14 (second equation)
To solve by elimination, starting with elimination of the y-variable, multiply the second equation by 3 to get a third equation.
2x - y = 14 (2nd eqn.) × 3
6x - 3y = 42 (3rd equation)
Add the 3rd equation and the 1st equation together.
x + 3y = 42 (first equation)
6x - 3y = 42 (3rd equation)
7x = 84
7x/7 = 84/7
x = 12
To find y, substitute x = 12 in the first equation
x + 3y = 42 (first equation)
12 + 3y = 42
12 + 3y - 12 = 42 - 12
3y = 30
3y/3 = 30/3
y = 10
Solution is x = 12, y = 10

Enter the number that belongs in the green box.
Enter
Answer:
7 boys
Step-by-step explanation:
We must find the median of the data given. A median is the "middle number" of a set of numbers ordered in increasing value.
Step 1, ordering the numbers:
We will start by ordering the numbers from smallest to largest. We have:
2, 2, 6, 8, 9, 12
Step 2, finding the "middle number":
Well...notice how there is an even amount of numbers in the data set. We can't exactly find one "middle number". We can however, narrow the list down to two "middle numbers."
We have 6 and 8.
Step 3, taking the average:
To find the median, we will take the average of the two "middle numbers."

The median is 7 boys.

At the market you can buy 5 bags of apples for $23.60. At the farm you can buy 7 apples for $32.76. Which is the better deal
Answer:
Market
Step-by-step explanation:
Market : 5 bags = $23.60
Farm : 7 apples = $32.76
Market = $23.60 ÷ 5
= $4.72 each BAG
Farm = $32.76 ÷ 7
= $4.68 each APPLE
Thus, market is the better deal because you will get 5 bags of apple for $4.72 for each bag.

Write the sentence as an equation use x to represent a number
“Six times the difference of 11 and a number is -72”
Answer:
6 × (11 - x) = -72 => x = 23
or
6 × (x - 11) = -72 => x = -1
Step-by-step explanation:
there are at least two possibilities, as the "difference between two numbers a and b can be excised as either a-b or b-a.
in any case, just following the sentence
Six times = 6 ×
difference of 11 and a number = 11 - x
is -72 = -72
so,
6 × (11 - x) = -72
and that is true for x = 23
but
the other direction is possible too
6 × (x - 11) = -72
and that is true for x = -1

(5x-3)=(3x+27) I dont understand
Answer:
x = 15
Step-by-step explanation:
(5x-3)=(3x+27)
Subtract 3x from each side
(5x-3x-3)=(3x-3x+27)
2x-3 = 27
Add 3 to each side
2x-3+3 = 27+3
2x= 30
Divide by 2
2x/2 = 30/2
x = 15

Dana enters a race where she has to cycle and run. She cycles a distance of 25km and then runs for 20km. Her average running speed is half of her average cycling speed. If dana completes the race in 5 hours, what is her average cycling speed !
Step-by-step explanation:
Let running speed = x.
So, cycling speed = 2x.
Total distance traveled = 20 + 25 = 45km
Time taken running = 20/x
Time taken cycling = 25/2c
Total time taken = 5 hours
So, 5 = 20/x + 25/2x
Solving this equation for x gives:
10x = 65. Thus x = 6.5
Since cycling speed = 2x, cycling speed = (6.5)(2)
So cycling speed is 13 km/h.
Hope it helps.
