Select all of the expressions that are equivalent to 8/5.
A. 5 x 1/8
B. 8 x 1/5
C. 2 x 4/5
D. 4 x 2/5
C. 2 x 6/5
Answer:
B, C, and D
Step-by-step explanation:
A) 5 x 1/8 is 5/1 times 1/8 which is 5/8 (Incorrect)
B) 8 x 1/5 is 8/1 times 1/5 (multiply straight across and you get 8/5 (Correct)
C) 2 x 4/5 (again, it's 2/1 just multiply straight across and you are basically only multiplying the two numerators each time. Because 1 times 5 will always be 5) (Correct)
D) Correct because 4 times 2 is 8 which is over 5, hence, 8/5 (Correct)
E) 2 times 6 is 12 over 5 which is 12/5, not 8/5. (Incorrect)

How is an inequality different from an equation? Give a real-world scenario in which you would write an inequality rather than an equation.
HELPPPPPPPPPPPPPPPP PLEASEEEEEEEEE
Answer: An equation is a mathematical statement that shows the equal value of two expressions while an inequality is a mathematical statement that shows that an expression is lesser than or more than the other. An equation shows the equality of two variables while an inequality shows the inequality of two variables.
Step-by-step explanation: Hope this helps! :D
one scenario can be that if you have less than or equal amount of money only then you can buy a certain thing......e.g : if price of a game is 40....then i should have money equal to or more than fourty to buy the game......
money>=40

Find the slope of the line that passes through (4,2) and (9,1)?
Answer: m= -1/5
Step-by-step explanation:
Find the Slope (4, 2) and (9, 1)
Slope is equal to the change in y over the change in x, or rise over run.
change in y
m = _________
change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise). y₂ − y₁
m = _____
x₂ − x₁
Substitute in the values of x and y into the equation to find the slope.
1 − (2)
m = _____
9 − (4)
Simplify the numerator.
−1
m = _____
9 − (4)
Simplify the denominator.
−1
m = _____
5
Move the negative in front of the fraction.
−1
m = _____
− 5
Answer:
The slope of the line is [tex]\displaystyle -\frac{1}{5}[/tex].
Step-by-step explanation:
We are given two coordinate points:
[tex](4, 2)[/tex][tex](9, 1)[/tex]We are asked to find the slope of the line.
We can use the rise-over-run formula to solve for the slope of the line.
[tex]\displaystyle \text{slope} = \frac{\text{rise}}{\text{run}}\\\\\text{slope} = \frac{y_2-y_1}{x_2-x_1}[/tex]
However, we firstly need to name our coordinate points.
In math, we can label our coordinates using the following label system:
[tex](x_1, y_1), (x_2, y_2)[/tex]
Therefore, we can also label our coordinates as such:
[tex]x_1 = 4[/tex][tex]y_1 = 2[/tex][tex]x_2 = 9[/tex][tex]y_2 = 1[/tex]Now, we can supply these values into the formula and solve for our slope, or a better known variable, m.
[tex]\displaystyle m = \frac{1 - 2}{9 - 4}\\\\m = \frac{-1}{5}\\\\m = -\frac{1}{5}[/tex]
Therefore, our slope is [tex]\displaystyle -\frac{1}{5}[/tex].

Upgrade to Premium
Step-by-step explanation:
Fractions consisting of integers are only undefined if the denominator is zero. All other combinations will give you a rational number.
42 / (-7)
We can multiply both halves of the fraction by -1 to move the negative sign into the numerator:
-42 / 7
Then divide 42 by 7 to get:

A company has recently been hiring new employees. Today the company has 33% more employees than it did a year ago. If there are currently
53,200 employees, how many employees did the company have a year ago?
Answer:
Sorry , I might be wrong : 35664
Step-by-step explanation:
So, first, we can find 33% of 53,200
That is 17,556
Then, we can subtract 17556 from 53,200
We get 35664

What additional piece of information would prove DABD ≅ DCBD?
Answer:
∠BAD ≅ ∠BCD
Step-by-step explanation:
The complete equation is attached.
Two triangles are congruent to each other if all their three sides are equal to each other and all their three angles are equal to each other.
The angle side angle (ASA) congruence theorem states that two triangles are congruent if two angles of one triangle is equal to two angles of the other triangle and also if their included side are equal.
Since AB = BC, ∠ABD = ∠CBD. For ∠ABD ≅ ∠CBD based on ASA then ∠BAD ≅ ∠BCD

What is the solution for the equation 4x – 10 = 2x?
Answer:
5x
Step-by-step explanation:
subtract 4x fromboth sides
4x-10=2x
-4x -4x
divide both sides by -2
-10=-2x
-10/-2=-2x/-2

A cyclist estimates that he will bike 80 miles this week. He actually bikes 75.5 miles. What is the percent error of the cyclist's estimate? Round the percent to the nearest hundredth if necessary.
Answer:
6%
Step-by-step explanation:
Estimated distance = 80 miles
Actual distance covered = 75.5 miles
We need to find the percent error of the cyclist's estimate. Its formula is given by :
[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]
Put all the values,
[tex]\%=\dfrac{80-75.5}{75.5}\times 100\\\\=5.96\%[/tex]
or
= 6%
So, the percentage error is 6%.
Answer:
5.96

Question 1 (5 points)
(02.01 LC)
Line segment AB has a length of 5 units. It is translated 3 units to the right on a coordinate plane to obtain line segment A prime B prime. What is the length of A prime B prime? (5 points)
a. 2 units
b. 3 units
c. 4 units
d. 5 units
Answer:
The answer to this question is b. 3 units
Answer:
D. 5 Units
Step-by-step explanation:
A translation is a different way of saying that the shape was moved. So since this is a movement nothing changed about the length of the line segment, meaning the line segment stayed 5 units.
-8 (c - 10) = - (c-3)
1 Remove parentheses.
-8(c-10)=−c+3
2 Regroup terms.
-8(c-10)=3−c
3 Expand.
-8c+80=3−c
4 Add 8c8c to both sides.
80=3−c+8c
5 Simplify 3-c+8c to 3+7c
80=33+7c
6 Subtract 33 from both sides.
80-3=7c
7 Simplify 80-3 to 77.
77=7c
8 Divide both sides by 7.
77/7 = c
9 Simplify 77/7 to 11.
11=c
10 Switch sides.
c=11

Answer: Choice C
x+y = 28
3x+4y = 100
===================================================
Explanation:
x and y are placeholders for nonnegative whole numbers.
Specifically,
x = number of three point questions
y = number of four point questions
Since we have 28 questions total, this must mean x+y = 28. That forms the first equation in our system of equations.
------------
Now let's form the second equation:
x = number of three point questions
3x = points we get from all the three point questions
y = number of four point questions
4y = points we get from all the four point questions
3x+4y = all points possible
3x+4y = 100 is the second equation
------------
So we have this system
[tex]\begin{cases}x+y = 28\\3x+4y = 100\end{cases}[/tex]
which fits the conditions in the instructions.
