Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-2(x - 4) = -16
Step 2: Solve for x
Distribute -2: -2x + 8 = -16Isolate x term: -2x = -24Isolate x: x = 12Step 3: Check
Plug in x to verify it's a solution.
Substitute: -2(12 - 4) = -16Subtract: -2(8) = -16Multiply: -16 = -16Here we see that -16 does indeed equal -16.
∴ x = 12 is a solution of the equation.

Last year, the seventh-grade enrollment at Main Middle School was 612 students. This year, the enrollment dropped to 489 students due to the opening of a new middle school. Which best reflects the percent change in enrollment at Main Middle School from last year to this year?
Answers
Answer:
The percent change in enrollment at Main Middle School was about 20%
Step-by-step explanation:
Percentages
There was a change of enrollments in the 7th grade at Main Middle School from 612 to 489 due to openings of a new school.
The change in the number of enrollments was 612 - 489 = 123.
To express it as a percentage, we divide by the original number and then multiply by 100:
[tex]\displaystyle \mathrm{Change} \% = \frac{123 }{ 612} * 100 \approx 0.2[/tex]
The percent change in enrollment at Main Middle School was about 20%

If a person was randomly selected, what is the probability that the person selected rock climbing given that the person is female?
Answers
Answer:80 % chance
Step-by-step explanation:
The required probability that the person selected rock climbing given that the person is female is 23%.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
As mentioned in the question,
Total person in the adventure sports = 100
female rock climbers = 23
The probability that the person selected rock climbing given that the person is female is given as,
= female rock climbers / Total person in the adventure sports
= 23/ 100
= 0.23
Thus, the probability that the person selected rock climbing given that the person is female is 23%.

Priva has so identical parcels
Each parcel has a mass of 17 kg correct to the nearest kilogram
Find the upper bound for the total mass of the 50 parcels
Answers
The upper bound is the smallest value that would round up to the next estimated value.
For example, a mass of 70kg, rounded to the nearest 10kg, has a lower bound of 65kg, because 65kg is the smallest mass that rounds up to 70kg. The upper bound is 75kg, because 75kg is the smallest mass that would round up to 80kg (the next increment)
Because each parcel has a mass of 17kg correct to the nearest kg, the degree of accuracy is to the nearest 1kg
1kg/2=0.5kg
Upper bound for each parcel is 17.5kg

Step-by-step explanation:
The distance between two points A(x₁,y₁) B(x₂,y₂) is given by the formula as follows :
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is used to find the distance between two points. It is an application of the Pythagorean theorem. Usually, the distance covered is equal to the product of speed and time. But when speed and time in not given but coordinates are given, then only we can use this formula.

An airplane descended 345 m in 10 seconds. What was the airplane’s rate of change in elevation? Show your work and don’t forget the unit!
Answers
Answer:
The airplane’s rate of change in elevation is 34.5 m/s.
Step-by-step explanation:
Given that,
An airplane descended 345 m in 10 seconds.
We need to find the airplane’s rate of change in elevation. Let the rate is R. Its rate is equal to the distance divided by time. So,
[tex]R=\text{velocity}=\dfrac{345\ m}{10\ s}\\\\=34.5\ m/s[/tex]
So, the airplane’s rate of change in elevation is 34.5 m/s.

Round your answer to the nearest tenth. Explain how you got to the answer.
Answers
Answer:
Mercury and helium
1034.8575
Step-by-step explanation:
Given that :
Melting point of substances :
Nickel: 2,651
Mercury: -37.89
Helium: -458
Copper: 1,984.32
Melting means change of solid to liquid
a) Which two elements have melting points that are closest in value?
The difference in Melting point between mercury and helium :
- 37.89 - (-458) = 420.11
Nickel and copper :
2651 - 1,984.32 = 666.68
Hence, element with melting point which are closest in value Are Mercury and helium
b) What is the average melting point of the substances?
Sum of the melting points / number of substances
(2,651 + (-37.89) + (-458) + 1,984.32) / 4
= 4139.43 / 4
= 1034.8575

F(x) = 4x - x to the second power
So you substitute x for the numbers under x.
The second answer under f(x) is wrong it’s suppose to be...
F(x) = 4(0) - 0 to the second power the answer is 0.
The third answer under f(x) is also wrong the answer is...
F(x) = 4(-1) - -1 to the second power the answer is -3.
Looking back I see that under x the number 2 in f(x) is wrong also.
The answer Is f(x) = 4(2) - 2 to the second power equals 4.

Juan wants to solve the equation below using the Distributive Property.4(6 – x) = 12What should Juan’s first step be?
A.Multiply 4 by x.
B.Subtract x from 6.
C.Distribute 4 to (6 – x).
D.Subtract 4 from both sides.
Answers
Answer:
C
Step-by-step explanation:
Juan's first step to solve the distributive property will be to distribute 4 to (6 – x). The correct option is C.
What is distributive property?This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.
Given that Juan wants to solve the equation below using the Distributive Property 4(6 – x) = 12.
The equation can be solved as:-
4(6 – x) = 12
24 - 4x = 12
4x = 36
x = 9
Hence, the value of x is 9 when the equation is solved by distribution.
