Answers

gina spent $3.45 in total. amy spent $3.43 in total. so gina spent more money and she spent 2 cents more

Answer:

Gina spent more money, she spent 2 more cents than Amy.

Step-by-step explanation:

Gina:     1.38x2=$2.76    1.38/2=69 cents

2.76+69= $3.45

Amy:     0.98x3=$2.94   0.98/2=49 cents

Answers

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

11x + 6 = 28

Answers

Answer:

X = 2

Step-by-step explanation:

11 x 2 = 22

22 + 6 = 28

Answer is 2
Explanation: you first try to isolate the x
And your only choice is to subtract the 6 so it cancels out on that side and whatever you do to one side you always have to do to another so 28-6 equal 22, 11x=22, now you divide by 11 making it x = 2. Hope this helps if you have any questions ask me

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

-5.5(2 - 6x) - 2.5x

Answers

Distribute -5.5(2-6x) first
-5.5 x 2 = -11 & -5.5 x -6x =33x
=> 33x - 11

33x - 11 -2.5x
subtract common like terms
33x - 2.5x = 30.5x

Answer: 30.5x -11

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.

Answers

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.

So if there are 26 questions on the test and each test is worth 123 points and only two types of questions on the test multiple choice worth three points and essays worth eight points so if you wanna do it the easy way just get the essay points 8 and divid it by the amount of points on the test which is 123 And you want to divide that and you will have your answer if you do the math correctly you will have 15 remainder three so there will be only 15 essay questions and one multiple-choice so yeah that is my answer well we can agree and disagree depends on you

great! I think that would work perfectly!

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!

1/64 is the fraction and the answer

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.
