Answer:
60 percent.
Step-by-step explanation:
Answer:
The answer is 62.5%
Step-by-step explanation:
So basically if u do
%/100= part/whole
1.Use cross product
P/100=40/64
40*100=4000
The p stand for percent
2. Divide the two numbers
64p/64= 4000/64
So what you can do is divide 4000 and 64 and you will get 62.5
P=62.5
solve for x

Answer:
Variables: you are correct
Coefficients: -2
Constant: 3/7
Step-by-step explanation:
Variables are letters used in math so you were correct.
Coefficients are numbers with a variable. So to find the coefficient you would look for a number "connected" to a variable. This would be -2 because it is being subtracted from the first term.
The constant is 3/7 because you could put it on a number line.
Simplify the expression

Diego’s history teacher writes a test for the class with 26 questions. The test is worth 123 points and has two types of questions: multiple choice worth 3 points each, and essays worth 8 points each.
How many essay questions are on the test? Explain your reasoning.
Answer: 9 essay questions
Step-by-step explanation:
The test has 26 questions
The test is worth 123 points
The test has two types of questions:
Multiple choice worth 3 points each
Essays worth 8 points each
Let the number of multiple choice questions be, m, and the number of essay questions be , e.
This forms a simultaneous equation below:
m + e = 26 ... (i)
3m + 8e = 123 ... (ii)
Multiplying (i) by 3 and (ii) by 1 we get:
3m + 3e = 78 ... (i)
3m + 8e = 123 ... (ii)
Subtracting (ii) - (i) we get;
0m + 5e = 45
5e = 45
e = 45 ÷ 5 = 9
So there are 9 essay questions.
and;
m + 9 = 26
m = 26 - 9 = 17
There are also 17 multiple choice questions.

Answer:
Length = 11 1/3 ft; Width = 4 2/3 ft
Step-by-step explanation:
First question:
The length is 2 more than twice the width, so
L = 2W + 2
Second question:
2L + 2W = 32
L = 2W + 2
Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.
2L + 2W = 32
2(2W + 2) + 2W = 32
4W + 4 + 2W = 32
6W = 28
W = 28/6 = 14/3 = 4 2/3
L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3
L = 11 1/3
W = 4 2/3
Answer: Length = 11 1/3 ft; Width = 4 2/3 ft

One stamp is randomly selected from a 10-by-10 sheet of 100 stamps. What is the probability that the stamp selected is not along an outer edge? Express your answer as a common fraction. Plz answer as soon as possible... thx!
The required probability of not stamp not along an outer edge is 8/25.
What is a fraction?A fraction is a numeral that represents a rational number.
Let a and b be two numbers, then their fraction can be represented as a/b.
Given that,
Total numbers of stamp in a stamp sheet of 10 by 10 = 100,
On one edge there would be 10 stamps but on each diagonal there will be 1 stamp common,
Therefore, total number of stamps on outer edge will be = 9 x 4 = 36
Remaining stamps = 100 - 36 = 64
The fraction value of 64 out of 100 = 64 / 100 = 8 / 25
The required fraction value of stamps is 8 / 25.
