4 over 10
2 over 8
3 over 5
4 over 12
6 over 10
3 over 6
Answer: 4/10 = 2/5
2/8 = 1/4
3/5 = 3/5
4/12 = 1/3
6/10 = 3/5
3/6 = 1/2
Step-by-step explanation:
4/10 = 2/5
4/10 is not in its simplest form.
Both 4 and 10 can be divided by 2.
Therefore, 4/10 = 2/5
2/8 = 1/4
2/8 is not in its simplest form
2 / 2 = 1
8 / 2 = 4
Both 2 and 8 can be divided by 2, therefore, 2/8 = 1/4
3/5 = 3/5
3/5 is in its simplest form
3 and 5 are prime, so they don’t have any factors other than 1 and itself so they wouldn’t be able to be simplified.
4/12 = 1/3
4/12 is not in its simplest form
4 / 4 = 1
12 / 4 = 3
4 and 12 can be divided by 4, resulting in 1 and 3. Therefore, 4/12 = 1/3.
6/10 = 3/5
6/10 is not in its simplest form
6 / 2 = 3
10 / 2 = 5
6 and 10 can both be divided by 2, resulting in 3/5. Therefore, 6/10 = 3/5
3/6 = 1/2
3/6 is not in its simplest form
3 / 3 = 1
6 / 3 = 2
Both 3 and 6 can be divided by 3, resulting in 1/2
Therefore, 3/6 = 1/2
Short Answers:
4/10 = 2/5
2/8 = 1/4
3/5 = 3/5
4/12 = 1/3
6/10 = 3/5
3/6 = 1/2

Answer:
42.5 square units
Step-by-step explanation:
To solve, we can split this shape up into 4 known shapes:
2 unit by 2 unit triangle
2 unit by 2 unit square
2 unit by 5 unit triangle
3.5 unit by 9.0 unit rectangle
Now let's solve these areas:
2 x 2 = 4 / 2 = 2
2 x 2 = 4
2 x 5 = 10 / 2 = 5
3.5 x 9.0 = 31.5
Then add all these values together:
2 + 4 + 5 + 31.5 = 42.5

Write an equation in slope intercept form for the line perpendicular to y = 2x - 3 that passes through the point (-3, -3)
Answer:
y=-1/2x-9/2
Step-by-step explanation:
check picture
The equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.
To find the equation of a line perpendicular to y = 2x - 3, we need to determine the slope of the original line and then find the negative reciprocal of that slope.
The original line has a slope of 2. The negative reciprocal of 2 is -1/2.
Now, we have the slope (-1/2) and the point (-3, -3) that the perpendicular line passes through.
We can use the point-slope form of a linear equation to write the equation of the line:
y - y1 = m(x - x1)
Substituting the values:
y - (-3) = (-1/2)(x - (-3))
y + 3 = (-1/2)(x + 3)
Expanding and simplifying:
y + 3 = (-1/2)x - 3/2
y = (-1/2)x - 3/2 - 3
y = (-1/2)x - 3/2 - 6/2
y = (-1/2)x - 9/2
Therefore, the equation of the line perpendicular to y = 2x - 3 that passes through the point (-3, -3) is y = (-1/2)x - 9/2 in slope-intercept form.

The length of a square table is 1.25m. An ant walks around the edge of the table.How far does the ant walk?
Answer:
5m
Step-by-step explanation:
1.25m multiply by 4 sides equals 5m
The length of which ant walk will be the same as the perimeter of the square thus it will be 5 meters.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
Perimeter of square = side + side + side + side
Given a table in form of a square,
Side of square = 1.25 m
The external measure of side = length of ant walk
1.25 + 1.25 + 1.25 +1.25 = Length of ant walkt
Length of ant walk = 5 meters.
Hence "The length of which ant walk will be the same as the perimeter of the square thus it will be 5 meters".

Light bulbs cost £3.40 each.
Yasmin buys as many as she can with £30.
How much change should she get?
Give your answer in pounds, £.
======================================================
Work Shown:
x = number of light bulbs
3.40x = total cost to buy x light bulbs, cost is in pounds
3.40x = 30
x = 30/(3.40)
x = 8.823529 approximately
Rounding down, we get 8
Note that,
3.40*8 = 27.20 pounds which is under budget3.40*9 = 30.60 pounds which is over budgetTherefore, the highest number of bulbs that can be bought is 8.
The change given will be 30-27.20 = 2.80 pounds

with (x₁, y₁ ) = (- 3, 4 ) and (x₂, y₂ ) = (2, - 1 )
m = [tex]\frac{-1-4}{2-(-3)}[/tex] = [tex]\frac{-5}{2+3}[/tex] = [tex]\frac{-5}{5}[/tex] = - 1 → A
Someone please answer this?
Answer:
y = 2x + 5
Step-by-step explanation:
First, you must choose two ordered pairs from the table to solve for the slope (m):
Let (x1, y1) = (0, 5)
(x2, y2) = (1, 7)
Substitute the given values into the following slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{7 - 5}{1 - 0} = \frac{2}{1} = 2[/tex]
Therefore, the slope (m) = 2.
The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b ). It is also the value of y when x = 0. Looking at the given table, (0, 5) reflects the description of the y-intercept. The y-intercept (b) is the y-coordinate of (0, 5).
Given the slope (m) = 2, and y-intercept (b) = 5, the linear equation is:
y = 2x + 5

the midpoint is ____
Answer:
( - 6, 1.5 )
Step-by-step explanation:
( x1, y1 ) = ( - 2, - 1 )
Here,
x1 = - 2
y1 = - 1
( x2, y2 ) = ( - 10, 4 )
Here,
x2 = - 10
y2 = 4
Formula : -
Mid - point = ( x1 + x2 ) / 2, ( y1 + y2 ) / 2
Mid - point = ( - 2 - 10 ) / 2, ( - 1 + 4 ) / 2
= - 12 / 2, 3 / 2
Mid - point = ( - 6, 1.5 )

Joseph owes his mother $12.25. He borrows $6.50 more from his mother. Which of the following best represents Joseph's debt to his mother?
Answer:
18.75.
Step-by-step explanation:
If he already owes his mother 12.25 and borrows 6.50, we can add those numbers up to get the total amount of how much he owes his mother.
12.25 + 6.50 = 18.75
Therefore, Joseph's debt to his mother can be represented using the equation above.
