Answer:b>-1 and 66/67
Step-by-step explanation:
First you add like terms. So 96+43. Your problem should now look like this -67+6=139. Now subtract 139 from 6 and you will be left with this -67b<133. Now divide 133 by -67 and you get -1.985074627. Or -1 66/67 as a fraction. You have to flip the sign because you divided by a negative number. You answer should look like this b>-1 and 66/67.

Mr. Hopkins has a 1-meter wire he is using to make clocks. Each fourth meter is marked off and
divided into 5 smaller equal lengths. If Mr. Hopkins bends the wire at - meter, what fraction of the
smaller marks is that?
Answer: fraction = 1/20 or 0.05
Step-by-step explanation:
Let's first convert metre to centimeter
1 metre = 100 centimeters
Given that Each fourth meter is marked off and divided into 5 smaller equal lengths. This means:
1/4 × 100 = 25
Then divide 25 into 5 places
25/5 = 5cm
If Mr. Hopkins bends the wire at - meter, what fraction of the smaller marks is that?
The fraction = 5/100 = 1/ 20 or 0.05

3. What is the area of the parallelogram below?
40.
Step-by-step explanation:
Base times height. This is a rhombus. 4 x 10 = 40. If you chop off the triangle to the right and place it on the left where 5 is, it'll be a rectangle. Formula for a rhombus is B x H, Base is 10, height is 4, and you get 40.
Using the Addition Method, solve for y in the following system of linear equations.
4x-2y=6
2x+y=7
Answer:
x = 3.33
y = 0.33
Step-by-step explanation:
to evaluate for y in this system of linear equation we would say that let
4x-2y=6 ........................................................... equation 1
2x+y=7 ..............................................................equation 2
from equation 2
2x+y=7 ..............................................................equation 2
y = 7 - 2x........................................... equation 3
substitute for y in equation 1
4x-2y=6 ........................................................... equation 1
4x -2( 7 - 2x) = 6
4x - 14 + 2x = 6
6x = 6 +14
6x = 20
divide both sides by 6
6x/6 = 20/6
x = 3.33
put x into equation 3
y = 7 - 2x........................................... equation 3
y = 7 -2( 3.33)
y = 7 -6.667
y = 0.33
Final answer:
To solve for y using the Addition Method, first manipulate the equations to have opposite coefficients for y, add them to find x, and then substitute x back into one of the original equations to solve for y. The solution is x = 2.5 and y = 2.
Explanation:
The student is asking how to solve for y in a system of linear equations using the Addition Method. The given system of equations is:
4x - 2y = 6
2x + y = 7
To use the Addition Method, we aim to eliminate one variable by adding the equations. First, we manipulate the equations to have opposite coefficients for the y variable. Multiply the second equation by 2:
(2x + y) × 2 → 4x + 2y = 14
Now we have:
4x - 2y = 6 (Equation A)
4x + 2y = 14 (Equation B)
Add Equation A and Equation B:
4x - 2y + 4x + 2y = 6 + 14
8x = 20
x = 20 / 8
x = 2.5
Substitute x back into the second original equation to solve for y:
2(2.5) + y = 7
5 + y = 7
y = 7 - 5
y = 2
Hence, the solution to the system of equations is x = 2.5 and y = 2.

Answer:
One of these numbers is a cube number which means that it could be 1,8, or 27 because those are the first three cube numbers.
If you go with one then you have to find two more numbers that add up to 35 and are a factor of 20, which is not possible.
Then you use 8, which means you have to find two numbers that add up to 26, and are factors of 20, which could be nothing, there aren't any.
Last you do 27 which means you need to find two numbers that add up to 9 and are factors of 27, which can be 4 and 5, because 4+5=9 and 4*5=20.

What is the radius of the circle without the equation to solve it?
Answer:
radious 7
diameter 14
Step-by-step explanation:
Final answer:
The radius of a circle can be found using the formula r = C/(2π), where r is the radius and C is the circumference of the circle.
Explanation:
The radius of a circle can be found using the formula r = C/(2π), where r is the radius and C is the circumference of the circle. Since the value of π is approximately 3.14159, you can divide the circumference of the circle by 2π to find the radius.
For example, if the circumference of the circle is 10 units, the radius would be 10/(2π) units.
Remember to use the appropriate units for both the circumference and the radius.

juan needs to measure 6 cups of flour for a recipe.he only has a 1/4 cup measuring cup.how many times must he fill the measuring cup to get 6 cups of flour
Answer:
Juan would need to fill up the 1/4 measuring cup 24 times.
Step-by-step explanation:
So to measure one cup of flour with a 1/4 measuring cup, you would need to fill up the 1/4 measuring cup 4 times. Since we want 6 cups, you would need to fill up the 1/4 measuring cup 24 times. 6 times 4 = 24. Hope this helps!
Juan would need to use his 1/4 cup measuring cup 24 times to get a total of 6 cups of flour. This is solved by multiplying the number of quarters (4) in a cup with the total cups Juan needs (6).
Explanation:In order to understand the problem, we need to consider that each cup contains 4 quarters. So, if 1 cup equals 4 quarters, then 6 cups, the amount Juan needs for his recipe, would be 6 multiplied by 4, which is 24. Therefore, Juan would need to fill his 1/4 cup measuring cup 24 times to get a total of 6 cups of flour.

In this picture b, d, and f are midpoints. Ac=50 ce=60 and bd=35. What is bf
Answer:
BF = 30
Step-by-step explanation:
Since B and F are midpoints of AC and AE then BF is a midsegment and is one half the measure of the third side CE, thus
BF = 0.5 × 60 = 30
The value of BF will be, 30 units.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In this picture;
B, D, and F are midpoints.
And, AC = 50, CE = 60 and BD = 35.
Here, C is midpoint of CE.
Hence, We get;

Use the definition of continuity and the properties of limits to show that the function f(x) = x^2 + 5(x - 2)^7 is continuous at x = 3
Answer:
See below.
Step-by-step explanation:
First check that f(x) has a real value at x = 3:
f(3) = 3^2 + 5(3 - 2)^7
= 9 + 5 * 1^7
= 14,
So the first condition is met.
Now we check if limit as x approaches 3 exists.
As x approaches 3 from below f(x) approaches 14 and at x = 3 = 14.
As x approaches 3 from above f(x) approaches 14 and at x = 3 = 14.
These 3 conditions shows that f(x) is continuous at x = 3.
The function f(x) = x^2 + 5(x - 2)^7 is continuous at x = 3 because it meets all the conditions of continuity: it is defined at x = 3, the limit of the function as x approaches 3 exists, and the limit equals the function's value at x = 3.
Explanation:The function f(x) = x^2 + 5(x - 2)^7 is continuous at x = 3 if it satisfies the following three properties: the function is defined at x = 3, the limit of the function as x approaches 3 exists, and the function value at x = 3 is equal to the limit as x approaches 3.
Step 1
The function is defined at x = 3. When we substitute x = 3, we get f(x) = 3^2 + 5(3 - 2)^7= 9 + 5*1^7 = 14.
Step 2
The limit of the function as x approaches 3 exists. As x approaches 3 from both the left and right sides, the function takes the value 14.
Step 3
Finally, the limit as x approaches 3 is equal to the function's value at x = 3. In other words, the limit is 14, which is equal to the function's value when x = 3 (which is also 14).
Since the function satisfies all these conditions, we can say that the function f(x) = x^2 + 5(x - 2)^7 is continuous at x = 3.

Answer:

Solve for x to the nearest degree (34.3 = 34)
Answer:
48°
Step-by-step explanation:
We can solve this using our knowledge on tangents of an angle. Remember, tangents are the opposite leg divided by the leg adjacent to that angle.
This means the tangent of x° = [tex]\frac{10}{9}[/tex]. Now that we know the tangent ratio, we can find the angle with inverse trigonometric ratios. These kinds of ratios give us the opposite of the tangent - which would lead to the angle measure we're looking for. The equation would look like this:
[tex]x = arctan (\frac{10}{9})[/tex]
Using a calculator, the answer would be:
[tex]x = 48.0128[/tex]
Rounding this to the nearest degree would give us 48° as our answer! I hope this was clear enough.
