Step-by-step explanation:
I hope this helps!
Answer:
5/6
Step-by-step explanation:
so for the first equation I would keep 1/3 the same
flip the division sign to multiplication
and turn the second fraction 4/10 upside down so it becomes 10/4
[tex]\frac{1}{3} *\frac{10}{4} =10/12[/tex]
10/12 can be simplified by dividing 2 on the numerator and denominator
10/2=5
12/2=6
5/6
for the second equation I know that each number in the first equation should be present in the second(since they are all the same numbers). However, 5/6 is not present in the second equation so that is the missing number

The equation of the line in the slope-intercept form is y = [tex]\frac{4}{3}[/tex] x + 4 ⇒ A
Step-by-step explanation:
The slope-intercept form is y = m x + b, where
m is the slope of the lineb is the y-intercept (y at x = 0)The formula of the slope of a line which passes through points [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
∵ The line passes through points (-6 , -4) and (0 , 4)
∴ [tex]x_{1}[/tex] = -6 and [tex]x_{2}[/tex] = 0
∴ [tex]y_{1}[/tex] = -4 and [tex]y_{2}[/tex] = 4
- Substitute them in the formula of the slope
∴ [tex]m=\frac{4--4}{0--6}=\frac{8}{6}[/tex]
- Simplify it by divide up and down by 2
∴ [tex]m=\frac{4}{3}[/tex]
∵ The slope-intercept form is y = m x + b
- Substitute the value of m on it
∴ y = [tex]\frac{4}{3}[/tex] x + b
∵ b is value y at x= 0
∵ At x = 0 , y = 4 ⇒ given point
∴ b = 4
- Substitute the value of b in the equation
∴ y = [tex]\frac{4}{3}[/tex] x + 4
The equation of the line in the slope-intercept form is y = [tex]\frac{4}{3}[/tex] x + 4

1.4375
Step-by-step explanation:
Step 1:
Let the given equation be [tex]1+12(4X-6)=-2[/tex]
To find X simplification of terms using BODMAS ( Brackets Orders Division Multiplication Addition Subtraction) is done as follows.
Step 2:
Let us expand the equation as [tex]1+ (12*4X)-(12*6)=-2[/tex]
Step 3:
Let us expand it further as [tex]1+48X-72=-2[/tex]
Step 4:
To find X segregate X in one side and all other remaining terms in other side as follows
[tex]48X=-2+72-1[/tex]
After the simplification the numerical value is
[tex]48X=69[/tex]
Step 5:
Keep X along one side and bring 48 to the denominator of another side to find X as follows
[tex]X=69/48[/tex]
And the value of X is 1.4375
Answer:
x = 1 7/16
Step-by-step explanation:
1 + 1 2 ⋅ (4x − 6) = −2
Subtract 1 from each side
1-1 + 1 2 ⋅ (4x − 6) = −2-1
1 2 ⋅ (4x − 6) = −3
Distribute the 12
48x -72 = -3
Add 72 to each side
48x-72+72 = -3+72
48x =69
Divide by 48
48x/48 = 69/48
x =1 21/48
x = 1 7/16

The combined result of the area of a square with a side of four units and the arithmetic expression (11 minus 9) divided by 2 is 17.
Explanation:Calculating the Combined Area and Arithmetic Expression
To solve the given problem, we need to calculate the area of a square with a side of four units and add this to the arithmetic expression (11 minus 9) divided by 2. First, let's find the area of the square. The area of a square is found using the formula area = side × side. Therefore, the area of our square is 4 units × 4 units = 16 square units.
Next, we calculate the arithmetic expression. The difference of eleven and nine is 11 - 9 = 2, and dividing this by two gives us 2 / 2 = 1.
Finally, we add the area of the square to this result: 16 square units + 1 = 17. The final answer is 17.

Kay is drawing a triangle. Two of the sides have an equal length of 8 cm, and the angle between those sides measures 68°. Which could be the measure of each base angle?
The measure of each base angle is 56°.
Step-by-step explanation:
The isosceles triangle has two base angles that are congruent (same measure).Let the measure of each base angle is 'x'.The sum of angles in a triangle add to 180°.base angle + base angle + 68° = 180°
2x + 68° = 180°
2x = 112°
x = 112/2
x = 56°
Therefore, the measure of each base angle is 56°.
The required measure of each base angle is equal to 56°.
It involves understanding the properties of an isosceles triangle, which is the key to solving the problem. In an isosceles triangle, if two sides are equal, the angles opposite those sides are also equal.
Given that Kay is drawing a triangle with two equal sides of 8 cm and the angle between these sides measures 68°, the triangle is isosceles, and we know that the other two angles (the base angles) are equal due to this property.
The sum of all angles in any triangle equals 180°. Therefore, to find the measure of each base angle, we subtract the given angle from 180° and then divide by 2 (since the base angles are equal):
The sum of angles in a triangle = 180°.
The measure of the angle between the two sides = 68°.
The sum of the two base angles = 180° - 68° = 112°.
Measure of each base angle = 112° / 2 = 56°.
Therefore, the measure of each base angle in Kay's triangle is 56°.
Absolute value equation |x-3|=5
Answer:
x = - 2, x = 8
Step-by-step explanation:
The absolute value function always returns a positive value, but the expression inside can be positive or negative, thus
x - 3 = 5 OR - (x - 3) = 5
Solving both equations
x - 3 = 5 ( add 3 to both sides )
x = 8
OR
- x + 3 = 5 ( subtract 3 from both sides )
- x = 2 ( multiply both sides by - 1 )
x = - 2
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are solutions.
x = 8
| 8 - 3 | = | 5 | = 5 = right side
x = - 2
| - 2 - 3 | = | - 5 | = 5 = right side
Thus the solutions are x = - 2, x = 8
The equation given is the same as x - 3 = 5 or -(x - 3) = 5
Steps to solve:
x - 3 = 5
x - 3 + 3 = 5 + 3
x = 8
Steps to solve:
-(x - 3) = 5
-x + 3 = 5
-x + 3 - 3 = 5 - 3
-x = 2
-x/-1 = 2/-1
x = -2
Therefore, the solutions are x = 8 and x = -2

Find the area of the complex figure.

Answer:
1863 [tex]meters^{2}[/tex]
Step-by-step explanation:
( 23 x 12 ) x 2 = 552
69 x 19 = 1311
1311
+552
= 1863 [tex]meters^{2}[/tex]
The area of the complex figure is 1,863 square meters
To find the area of the complex figure, break it down into individual rectangles and then sum up their areas. The complex figure consists of two smaller rectangles and one larger rectangle.
For the first two rectangles:
- Length = 23 m
- Width = 12 m
The area of each of the first two rectangles is:
Area = Length × Width = 23 m × 12 m = 276 square meters
Now, for the larger rectangle:
- Length = 69 m
- Width = 19 m
The area of the larger rectangle is:
Area = Length × Width = 69 m × 19 m = 1,311 square meters
To find the total area of the complex figure, sum up the areas of the three rectangles:
Total Area = Area of the first two rectangles + Area of the larger rectangle
Total Area = (276 square meters + 276 square meters) + 1,311 square meters
Total Area = 552 square meters + 1,311 square meters
Total Area = 1,863 square meters
So, the area of the complex figure is 1,863 square meters. This approach demonstrates how to find the area by breaking down the complex figure into simpler shapes and summing their individual areas.

The length of a rectangular piece of sheet metal is 3 times it’s width. What is its length if it’s area is 192 square centimeters
To find the missing number, you will need to divide the numbers you already have.
192 divided by 3 = 64
Your answer/length will be 64.
Area = 192
Width = 3
Length = 64
64 x 3 = 192
Hope this helps :)
To determine the length of the rectangular piece of sheet metal with an area of 192 square centimeters and a given length-to-width ratio, solve for the width using the area formula, then use the ratio to find the length. The calculated length is 24 centimeters.
The problem involves finding the length of a rectangle given the area and the relationship between the length and width. Let's denote the width of the rectangle as w and the length as L. We are given that L = 3w and the area (A) of the rectangle is 192 square centimeters. The area of a rectangle is calculated by multiplying its length and width.
A = L x w
Substituting L from the given relationship into the area equation:
192 cm² = (3w) x w
Now we can solve for w:
192 cm² = 3w²
w² = 192 cm² / 3
w² = 64 cm²
w = 8 cm
Now, use the value of w to find L:
L = 3 x 8 cm
L = 24 cm
Therefore, the length of the rectangular piece of sheet metal is 24 centimeters.

The length of a rectangle is 3 centimeters less than twice the width. If the perimeter of the rectangle is 24 centimeters, find its dimensions.
Answer:
Width = 5 cm
Length = 7 cm
Step-by-step explanation:
Width = w
Length = 2w - 3
Perimeter = 24 cm
2* (length + width ) = 24
2*(2w-3 +w) = 24
2*(3w -3) = 24
3w - 3 = 24/2
3w - 3 = 12
3w = 12+ 3
3w = 15
w = 15/3
w = 5cm
Length = 2w - 3 = 2*5 - 3 = 10-3 = 7 cm
length = 7 cm
