Answers

I’m pretty sure it’s 1 and 2

72×10+72×3 and 72×2+72×1 shows clustering for the problem 72 x 13

What is Number system?

A number system is defined as a system of writing to express numbers.

The given expression is 72 x 13.

Seventy two times of thirteen.

We can write this 72×(10+3)

By distributive property

72×10+72×3

So 72×10+72×3 shows the clustering for the problem 72 x 13.

and we can also write this as given 72×(12+1)

72×2+72×1 also shows the clustering for the problem 72 x 13.

Hence, 72×10+72×3 and 72×2+72×1 shows clustering for the problem 72 x 13

1. 42+14x
2. 3(2x + 9)

Answers

Answer:

1. 56x 35x

what you had to do was add 42 plus 14x which gives you 56x. then for number two you had to multiply the numbers inside of the parenthesis by the number outside of the parenthesis which will give you 35x.

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

With you here, and with us in my own home, in the long run, success or failure will be conditionedupon the way in which the average man, the average women, does his or her duty, first in the ordinary, every-day affairs of life, and next in thosegreat occasional cries which call for heroic virtues. The average citizen must be a good citizen if our republics are to succeed. The stream will notpermanently rise higher than the main source; and the main source of national power and national greatness is found in the average citizenshipof the nation. Therefore it behooves us to do our best to see that the standard of the average citizen is kept high; and the average cannot bekept high unless the standard of the leaders is very much higher.Let the man of learning, the man of lettered leisure, beware of that queer and cheap temptation to pose to himself and to others as a cynic, asthe man who has outgrown emotions and beliefs, the man to whom good and evil are as one. The poorest way to face life is to face it with asneer. There are many men who feel a kind of twister pride in cynicism, there are many who confine themselves to criticism of the way others dowhat they themselves dare not even attempt. There is no more unhealthy being, no man less worthy of respect, than he who either really holds,or feigns to hold, an attitude of sneering disbelief toward all that is great and lofty, whether in achievement or in that noble effort which, even ifit fails, comes to second achievement. A cynical habit of thought and speech, a readiness to criticise work which the critic himself never tries toperform, an Intellectual aloofness which will not accept contact with life's realities - all these are marks, not as the possessor would fain to think,of superiority but of weakness. They mark the men unfit to bear their part painfully in the stern strife of living, who seek, in the affection ofcontempt for the achievements of others, to hide from others and from themselves in their own weakness.
