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 1

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 2
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

Answers

Answer:

Step-by-step explanation:

The correct pairs of equivalent expressions are given below.

⇒ (5 + 2b)+(2b + 3/2) =  4b + 13/2

⇒ (-10 + b)+(7b - 5) =  8b - 15

⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b

⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11

What is the expression?

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

We have given that,

All the expression are,

(5 + 2b)+(2b + 3/2)

(-14 + 3/2b)-(1 + 8/2b)

(-10 + b)+(7b -5)

(7/2b - 3)-(8 + 6b)

Now, We have to determine the equivalent expression as;

⇒ (5 + 2b)+(2b + 3/2) =  4b + 13/2

⇒ (-10 + b)+(7b - 5) =  8b - 15

⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b

⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11

Thus, The correct pairs of equivalent expressions are given below.

⇒ (5 + 2b)+(2b + 3/2) =  4b + 13/2

⇒ (-10 + b)+(7b - 5) =  8b - 15

⇒ (-14 + 3/2b)-(1 + 8/2b) = -15 - 5/2b

⇒ (7/2b - 3)-(8 + 6b) => -5/2b - 11

MR. ARCEO TAKES A TAXI FROM THE AIRPORT TO A HOTEL. THE TAXI CHARGES $2.50 INITIAL CHARGE PLUS $2.65 PER MILE. WHICH EQUATION CAN BE USED TO FIND Y, THE TOTAL COST OF THE TRIP, IF X REPRESENTS THE NUMBER OF MILES OF THE TRIP?

Answers

2.65x + 2.50 = y

step by step explanation:

2.65 is how much for each mile, and the variable, x, represents the number of miles of the trip. so, we would do 2.65x to find out how much money you have to pay for the amounts of mile.

next, you would have to add the initial fee, which is 2.50. so 2.65x+2.50.

lastly, y represents the total cost of the trip. so, 2.65x + 2.50 = y

Question 2
b. The bridge has a length of 26,372 feet. What is the length in kilometers? Round to the nearest hundredth.

The length of the bridge is about ____ kilometers.

Answers

a: 60.66 m
b:8.04 km

The roadway is about 60.66 meters above the water.

The length of the bridge is about 8.04 kilometers.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 km = 1000 m

We have,

The length of the roadway above the water = 199 ft

1 ft = 0.3048 m

Multiply 199 on both sides.

199 ft = 60.66 m

The bridge has a length of 26,372 feet.

1 ft = 0.0003048

Multiply 26372 on both sides.

26372 ft = 26372 x 0.0003048

26372 ft = 8.04 km

Thus,

The roadway in meters is about 60.66 meters above the water.

The length of the bridge in km is about 8.04 kilometers.
