Consider this expression: 3(3n + 6z)
Enter an expression that shows the sum of exactly two terms that is equivalent to 2(3n+ 6z).
The sum of the expression 70a and 21b is equivalent to 7(10a + 3b).
Step-by-step explanation:
EquationAn equation is an expression that is used to show the relationship between two or more variables and numbers.Given the expression:7(10a + 3b)Opening the bracket:= 70a + 21bThe sum of the expression 70a and 21b is equivalent to 7(10a + 3b).
If h(x) = x" for some positive constant a, and
h(27x) = 3h(x) for all positive values of x, what is
the value of a ?
By using the natural logarithm, we will see that the value of a is 0.33
How to get the value of a?
We know that:
h(x) = x^a
And we know that:
h(27x) = 3h(x).
We can rewrite this as:
(27x)^a = 3*(x)^a
And remember that we can distribute exponents, so the left side can be rewritten as:
(27*x)^a = (27^a)*(x^a)
Then we have:
(27^a)*(x^a) = 3*(x)^a
This means that:
27^a = 3
Now remember the rule:
ln(x^n) = n*ln(x)
If we apply the natural logarithm to both sides, we get:
ln(27^a) = ln(3)
a*ln(27) = ln(3)
a = ln(3)/ln(27) = 0.33

A stock rises in value from $20 to $40. Then it decreases in value from $40 to $20. Is the percentage increase from $20 to $40 the same as the percentage decrease from $40 to $20? Explain.
Answer:
No
Step-by-step explanation:
To find how much something is a percent of another number, divide it by said other number
20/40 = 0.5
0.5 × 100 = 50%
The first one is a 50% increase
Then, 40/20 = 2
2 × 100 = 200%
It is a 200% decrease
So no, because 50% doesn't equal 200%

After a successful Friday night at the local BDubs, 92% of the daily allocated wings were sold to restaurant-goers. The kitchen staff was a bit upset because that meant there were only 96 wings left between them to take home at the end of night. How many wings did BDubs start off with that night?
Answer:
88
Step-by-step explanation:
92% = 0.92
0.92(96) = 88.32
88 is rounded to the nearest wing

Answer:
Some equations are easy to solve in your head. If the numbers are easy to work with, you just have to figure out what question you need to answer. For example, to solve x + 8 = 12, you have to determine what number can be added to 8 in order to have a sum of 12. In this case, x must be equal to 4.
Other equations, however, are much harder to solve using mental math. Equations that have lots of negative numbers, large numbers, fractions, or decimals can be difficult to solve in your head. That's why there is a system, called an algorithm, for solving these equations.
An algorithm is just a step-by-step process for solving problems. The algorithm for solving equations is based on a very important property called the property of equality, which says that whatever is done to one side of the equation must also be done to the other side.
The algorithm for solving equations has four steps:
Locate the variable.
Determine what operation is being done to the variable.
Do the inverse operation on both sides of the equation.
Check your solution using substitution.
Remember that the goal of solving an equation is to determine what value of the variable will make the sentence true. This means you need to find what the variable is equal to. That's why the first step, although it may seem easy, is so important. You need to start by locating the variable in the equation. Take a look at Ondi's equation from above:
n - 1.4 = 3.7
In this case, the variable is n, and it's on the left side of the equation. That was easy! Now for the second step. Remember that the goal is to figure out what the variable is equal to when it's by itself. So in the second step, you have to identify what is being done to the variable in the equation. If you look at the equation above, you can see that 1.4 is being subtracted from n. The second step is complete!
The third step is when you actually start working with the equation. You're going to do the opposite of what is already being done to the variable. For example, if a number is added, you're going to subtract. If a number is subtracted, you're going to add. This will help you get the variable by itself on one side of the equation. Then you'll know what the variable is equal to!
In the equation, 1.4 is being subtracted from n. So you're going to do the opposite and add 1.4. Remember that the property of equality says that if you do something to one side of the equation, you must do it to the other side as well. Take a look:
n - 1.4 + 1.4 = 3.7 + 1.4
Can you see what is going to happen on the left side of the equation? Subtracting 1.4 and adding 1.4 cancel each other out, leaving you with just n. That's because subtraction and addition are inverse operations, which means they undo each other.
So the left side of the equation simplifies to the variable n. What will happen on the right side? The constants 3.7 and 1.4 will combine to give you 5.1.
n = 5.1
The fourth and final step of the algorithm is to check the solution using substitution. Substitute the value of 5.1 in for n in the original equation to see if the sentence is true:
n - 1.4 = 3.7
5.1 - 1.4 = 3.7
3.7 = 3.7
Yes! This statement is true, so the solution is correct!

Krystal Ball's pulse rate is 30% higher than its normal rate of 70bpm. What is her pulse rate? After
lying down it decreased 20%. What is her heart rate now?
Starting bpm = 91
Resting bpm = 72.8
=========================================================
Explanation:
A 30% increase is represented by the multiplier 1.30 because
100% + 30% = 1.00 + 0.30 = 1.30
So Krystal's initial heart rate is 1.30*70 = 91 bpm.
If you wanted, you can think of it like this
30% of 70 = 0.30*70 = 21 is added onto the initial 70 bpm to get 70+21 = 91 bpm.
-----------
To decrease by 20%, we use the multiplier 0.80 since
100% - 20% = 1.00 - 0.20 = 0.80
Losing 20% of something means we keep the remaining 80%
So,
80% of 91 = 0.80*91 = 72.8 bpm.
-----------
Here's one way to find the final bpm in one single line
1.30*0.80*70 = 72.8
in which you could write it like this
(1 + 0.30)*(1 - 0.20)*(70) = 72.8
The second way may be a bit longer, but I find it's more descriptive to see where the percentage increases vs percentage decreases are.
There were 20 balloons at the beginning of a party. By the end of the party,n of them had popped. using n, write an expression for the number of the balloons that were left
expression: 20 - n
total balloons = 20popped balloons = nnumbers of balloons left = total balloons - popped balloons
numbers of balloons left = 20 - n
Answer:
20 - n balloons remained
Explanation:
To find how much balloons remained after the party, we need to subtract the number of balloons popped from the total balloons.Finding how much balloons remained:
We know that there were 20 balloons at the beginning of the party and n balloons popped when the party was over.20 - n balloons remained.
Lucy makes 5 digit numbers using all these cards
3 4 6 7 9
how meny different numbers greater than 50,000 can she make
The selection of the 5-digit number illustrates arrangements
There are 1875 different numbers greater than 50000
How to determine the numbers?The digits of the 5 digit numbers are given as:
3 4 6 7 9
For the number to be greater than 50000, the first digit must be 6, 7 or 9 i.e. 3 numbers.
The other four digits can be any of the 5 numbers.
So, the count of numbers greater than 50000 is:
Count = 3 * 5 * 5 * 5 * 5
Count = 1875
Hence, there are 1875 different numbers greater than 50000

Use the discriminant to determine the number and type of solutions the equation has.
x2 + 6x + 12 = 0
two rational solutions
two irrational solutions
no real solution
one real solution
Answer:
no real solutions
Step-by-step explanation:
x² + 6x + 12 = 0
the general solution :
x = (-b ±sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 6
c = 12
the discriminate is (b² - 4ac).
so,
x = (-6 ± sqrt(6² - 4×1×12))/(2×1)
the discriminate is
6² - 4×12 = 36 - 48 = -12
this is negative, so via the square root of a negative number we get 2 complex (imaginary) solutions.
Find the distance from point L to point M, if the point L has coordinates (-10,-9)
and the point M has coordinates (-2,6).
Answer:
The distance from point L to point M is 17
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is calculated as follows:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Point L has coordinates (-10,-9) and point M has coordinates (-2,6).
Calculate the distance between L and M:
[tex]d=\sqrt{(6+9)^2+(-2+10)^2}[/tex]
[tex]d=\sqrt{15^2+8^2}[/tex]
[tex]d=\sqrt{225+64}=\sqrt{289}[/tex]
