An angle measures 46° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
67 degree
113 degree
Step-by-step explanation:
Supplementary angles are angles that measure up to 180 degrees. For example, if one angle measures 60 degree, the other angle would measure (180 - 60) 120 degrees
Let x represent the smaller angle
The bigger angle = x + 46
We know that both the smaller and the bigger angle would add up to 180, thus this equation can be written :
x + 46 + x = 180
2x + 46 = 180
Collect like terms
2x = 180 - 46
2x = 134
Divide both sides by 2
x = 67 degrees
the bigger angle = 67 + 46 = 113 degree

4 1/2, square root of 24, 5, 5.1
Answer:
answer is option d. 4 1/2, sq24, 5, 5.1
Step-by-step explanation:
Simplify the expressions that are needed to be simplified in order to list them from least to greatest.
[tex]\sqrt{24}[/tex] = 4.898....
[tex]4\frac{1}{2}[/tex] = 4.5
5.1
5
Now that we have all of our measurments, we can order them from least to greatest.
[tex]4 \frac{1}{2}[/tex], [tex]\sqrt{24}[/tex], 5, 5.1

Solve for x:
x/7 - 6 = 3
A. 27
B. -63
C. -27
D. 63
Answer:
D. 63
Step-by-step explanation:
First, add 6 to both sides:
[tex]\frac{x}{7}[/tex] - 6 = 3
[tex]\frac{x}{7}[/tex] = 9
Multiply each side by 7
x = 63
So, the correct answer is D. 63
Simplify 6⋅ (x+3)
Apply the distributive property.
6x+6⋅3=x⋅76x+6⋅3=x⋅7
Multiply 66 by 33.
6x+18=x⋅76x+18=x⋅7
Move 77 to the left of xx.
6x+18=7x
Move all terms containing x to the left side of the equation.
subtract 7x7x from both sides of the equation.
6x+18−7x=06x+18-7x=0
Subtract 7x7x from 6x6x.
−x+18=0-x+18=0
Subtract 1818 from both sides of the equation.
−x=−18-x=-18
Multiply each term in −x=−18-x=-18 by −1
Multiply −1-1 by −1-1.
1x=(−18)⋅−11x=(-18)⋅-1
Multiply xx by 11.
x=(−18)⋅−1x=(-18)⋅-1
Multiply−18-18 by −1-1.
x=18

Choose the list that contains all of the possible rational solutions of
x4 – x3 – 3x2 – 8x + 20 = 0.
A. 1, 2, 4, –1, –2, –4
B. 1, 2, 3, 4, –1, –2, –3, –4
C. 1, 2, 4, 5, 20, –1, –2, –4, –5, –20
D. 1, 2, 4, 5, 10, 20, –1, –2, –4, –5, –10, –20
We want to choose the list that contains all the solutions of the given equation, by graphing it, we will see that the correct option is the first one, A.
So our equation is:
x^4 - x^3 - 3x^2 - 8x + 20 = 0.
The solutions of that equation are all the values of x such that the equation:
y = x^4 - x^3 - 3x^2 - 8x + 20
Intercepts the x-axis.
Then we can use a graphing tool to graph the polynomial and we will get the graph you can see below:
There we can see that there is only one solution, which is x = 2.
Then the correct option will be A, which is the smallest set that contains the solution (notice that all the sets contain it, so we choose the smaller one).

work out the median of 1/3, 2/5, 1/4, 3/10, 3,20
Answer:
1/3 and 2
OR
3/10
(read sbs explanation)
Step-by-step explanation:
Order the numbers in order from least to greatest:
1/4, 3/10, 1/3, 2/5, 3, 20
Take the middle one, so the answer is 1/3, 2/5 as they are the two middle numbers. If you messed up your typing and the last numbers are supposed to be 3/20 not 3 and 20, your answer would be 3/10.

What is the maximum and minimum whole number side length for triangle XYZ with giving side lengths of 3cm and 5cm Please explain why
Answer:
maximum length is 7 cm.
minimum length is 3 cm.
Step-by-step explanation:
In a triangle, the sum of the lengths of two sides is larger than the value of the other side.(Here, the last side would be the longest side)
3+5=8 so the biggest whole number less than 8 is 7.
So, the maximum whole number side length is 7 cm.
Also, the difference between the lengths of two sides is less than the length of the other side.
5-3=2 so the smallest whole number greater than 2 is 3.
So, the minimum whole number side length is 3 cm.

Step-by-step explanation:
When solving multiple choice problems, a reasonable strategy is to look for ways to identify one answer as good, or other answers as bad.
Here, all of the constant vectors in the equations are different, so we can decide the answer based on that.
The only equation with the correct constant vector is choice B.

At the same rate of speed, how far could she ride in 8 hours?
Answer:
28
Step-by-step explanation:

She rode 7 miles in 2 hours, so because she is going at the same speed you times/multiply 7 x 4 in order to determine the miles. I timed it by 4 because 2 hours times 4 = 8 hours.
