Answer 2

The expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

An expression that has a value of 31

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

A) 3√25 + 7-5

= 3(5) + 7 - 5

= 15 + 7 - 5

= 17

B) (3√25) +7-5

= (3x5) +7-5

= 15 +7-5

= 17

C) 3√25+ (7-5)

= 3x5 +2

= 17

D) 3(√25 + 7) - 5

= 3(5+7) - 5

= 36 - 5

= 31

Thus, the expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.

Step-by-step explanation:

The denominators are 2, 3, and 4.  The least common denominator is the least common multiple (LCM) of these numbers.

To find the LCM, first write the prime factorizations.

2 = 2¹

3 = 3¹

4 = 2²

The LCM is therefore 2² × 3 = 12.

Rewrite the fractions with a denominator of 12.

⁷/₄ + ¹/₂ + ⁵/₃ + ¹/₃ + ¹/₄ + ¹/₂

= ²¹/₁₂ + ⁶/₁₂ + ²⁰/₁₂ + ⁴/₁₂ + ³/₁₂ + ⁶/₁₂

Now that the denominators are the same, we can simply add the numerators.

= ⁽²¹⁺⁶⁺²⁰⁺⁴⁺³⁺⁶⁾/₁₂

= ⁶⁰/₁₂

Sharon is planning a holiday for 4 people for 7 days

Here are the costs for the holiday for each person

Travel-£130 hotel-£60 for each day spending money-£350
Work out the total cost of the holiday for 4 people for 7 days

Answers

Answer:

3600

Step-by-step explanation:

Each PERSON cost:

Travel cost 130 (assume for whole 7 days since per day is not written)

Hotel 60 per day (so 7 days = 60 * 7 = 420)

Money Spend 350 (assume for whole 7 days since per day is not written)

-------------------------------------------------------------------------------------------------------------

Now, that sums to:

130 + 420 + 350 = £900 [each person for whole 7 days]

Now, there are 4 person, so total cost of whole group (4 persons):

900 * 4 = £ 3600


What conclusion can you draw from the following statements using the Law of Syllogism?
• If a figure is a square, then it has four sides.
• If a figure has four sides, then it is not a triangle


The potions for the answer is in the photo

Answers

Using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.

The law of Syllogism is a method of deductive reasoning which involves drawing a conclusion from two premises.

Applying this law, there are usually three statements.

The first and second statements are the premises. The first statement is the major premise that connects to the second statement.

The third statement is the conclusion derived from the two premises stated earlier.

For example:

Statement 1: If a, then b (premise)

Statement 2: If b then c (premise)

Statement 3: If a, the c (conclusion)

In the question above, in the same vein, from the first and second statement, we can conclude that:

If a figure is a square, then it is not a triangle, because a square has 4 sides and a triangle doesn't.

Therefore, using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.

Solve the following literal equation for x.

ax-b/c=d

Answers

Answer:

x = (d + b/c)/a

or x = d/a + ba/c

Step-by-step explanation:

1. ax - b/c = d

2. ax = d + b/c

3. x = (d + b/c)/a  (can also be written as x = (d + b/c)*1/a)

4. x = d/a + ba/c

Step 1 is given.

In step 2, b/c was added to both sides of the equation. This works because division is ahead of subtraction in the order of operations.

In step 3, both sides were divided by a.

(optional) In step 4, 1/a was multiplied by the values inside the parenthesis as a means to further simplify the equation.

If the measures of two angles of a triangle are 87 and 17 ​, what is the measure of the third​ angle

Answers

Answer:

76 degrees

Step-by-step explanation:

The total of the three angles in a triangle should equal 180 degrees. So to find the third angle, subtract the two given angles from 180

180 - 87 = 93

93 - 17 = 76

The third angle is 76 degrees because then all angles will add up to 180
