Answer:
x = 7
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
7x - 6 = 8 + 5x
Step 2: Solve for x
Subtract 5x on both sides: 2x - 6 = 8Add 6 to both sides: 2x = 14Divide 2 on both sides: x = 7Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 7(7) - 6 = 8 + 5(7)Multiply: 49 - 6 = 8 + 35Subtract/Add: 43 = 43Here we see that 43 does indeed equal 43.
∴ x = 7 is a solution of the equation.
Answer
7(7x)-6=8+5(7x)
49-6=8+35
43=43

If (x – 2k) is a factor of f(x), which of the following must be true? f(2k) = 0 f(–2k) = 0 A root of f(x) is x = –2k. A y intercept of f(x) is x = 2k.
Answer:
f(2k0=0
Step-by-step explanation:
answer a
The correct statement about function is,
⇒ f (2k) = 0
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.\
Given that;
(x – 2k) is a factor of function f(x),
Since, (x – 2k) is a factor of function f(x),
Hence, x = 2k is a factor of function f(x),
Thus, We get;
⇒ f (2k) = 0
Thus, The correct statement about function is,
⇒ f (2k) = 0

Which of the following is a like term of -5.92?
Answer:
C. -7.78
Step-by-step explanation:
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
Step 1: Keep the denominator the same. Step 2: Add or subtract the numerators. ...
Step 1: Find the Lowest Common Multiple (LCM) between the denominators. ...
Step 1: Convert all mixed numbers into improper fractions. ...
In this second method, we will break the mixed number into wholes and parts. ...
Thus, is equivalent to.
Fractions
Fractions can be thought of as another way of seeing division. If you have one whole pizza and two people want to share it equally, they will divide it into two halves:
The bottom number of a fraction is the denominator. It tells how many parts a whole has been divided into. In this case our pizza is divided into two parts.
Proper Fractions, Improper Fractions, and Mixed Numbers
A proper fraction is one in which the numerator is smaller than the denominator.
An improper fraction is one in which the numerator is larger than the denominator. If the numerator is larger than the denominator, the fraction equals a number that is greater than one.

Finding the GCF (Greatest Common Factor)
The greatest common factor is the largest factor that divides two numbers. We find this by figuring out what prime numbers are multiplied together to make up each number. A prime number is a number that can only be divided by itself or by one. Examples of prime numbers are 1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, etc. We want to focus on those that are less than ten in most cases.

Adding and Subtracting Fractions
To add or subtract two fractions, the two fractions must have the same denominator. Therefore, you will have to find the lowest common denominator and change each fraction to an equivalent fraction. Then you add or subtract the numerators as indicated and put the resultant number over the denominator and reduce the fraction to lowest terms.

1. Two students conducted similar experiments. The results of their experiments are
very different. What is the best step for the students to take next?
A. Change the experiment that is not correct.
B. Determine that both students are in correct.
C. Assume that both students' results are reliable,
D. Replicate the experiment to see whose results are more reliable.
Answer: D. Replicate the experiment to see whose results are more reliable.
Step-by-step explanation:
The experiments are similar, then we should expect to see similar results.
Now, we know that they get different results, let's analyze the options:
A) With the given information we can not conclude which is the incorrect experiment, then this is discarded.
B) We can not really determine that both students are in correct only knowing the experiment and the results, so this is also discarded.
C) You can not assume things.
D) This is the correct option, an experiment must be repeatable. This means that, with the same conditions, the result must be always the same.
Then we can replicate both experiments and see if the results are the same as before to determine if the results are reliable.

Write rate as a untit rate for240 miles in 6 hrs
Answer:
40 mph or 40 miles per hour
Step-by-step explanation:
If there is 240 miles in 6 hours, so you can divide the 240 by 6 to get the unit rate of miles per hour.
240 divided by 6 is 40
Answer: 240 miles in 6 hours as a unit rate would be 240 over 6. This is because with unit rates to find how many miles in one hour you would divide 240 by 6. (This would give you 40.)

Solve for y 2/5x + y = 3
Answer:
y=-2/5x +3
Step-by-step explanation:
You get the y to be alone on it's side of the equal sign.
So you subtract 2/5 x from that side and what you do to one side you have to do to the other.
You get: y=-2/5x +3
Two expressions with equal sign is Equation. y= 3-2/5x is the solution for y if equation is 2/5x + y = 3.
What is Equation?Two expressions with equal sign is called as Equations.
Given Equation is 2/5x + y = 3, we need to solve for y.
You get the y to be alone on it's side of the equal sign.
So you subtract 2/5 x from that side and what you do to one side you have to do to the other.
2/5x + y = 3
y = 3-2/5x
Therefore y=3-2/5x is the solution for 2/5x + y = 3 equation.

The perimeter of a rectangle is 304 cm. The length is 40 cm longer than the
width. Find the length and width. show steps pls
Answer:
p=2(L+W)
p=304
L=40+w
p=2(40+w+w) ,40+w is the value of L
304=2(40+2w)
304/2=2(40+2w)/2 divided both side by 2
152=40+2w
152-40=2w
112=2w
112/2=2w/2
w=56
and L =40+w
40+56=96.
so L=96 and W=56.

Answer:
1/6
Step-by-step explanation:
If you divide the fractions to decimals 1/6 equals .16 which is closest to 0
Answer:
to acuratly measure the value of each fraction to determine which fraction is closest to 0 we need to get a common denom:
1/6---->2/12
11/12
5/6---->10/12
10/12
Now that we hahve a common denom we just need to find the smallest numerator value of these fractions.
2/12 or 1/6 is closest to 0 since it's the lowest value
