Help please logarithms​

Mathematics
1 answer:
DochEvi [55]3 years ago
6 0

Answer:

Simplified: 40

Step-by-step explanation:

To simplify this, we need to first separate the terms in this expression. There is a property of exponents that says: x^{a+b} =x^ax^b We can do this same thing to simplify this expression. Next, we can simplify each of these terms. 2^2 simply becomes 4. In the other term, the 2^{log_2} simply cancel each other and leave the 10. This means that we're left with 4*10, which is 40

2^{2+log_210} \\\\2^2*2^{log_210} \\\\4*10\\\\40

<em>The following angle is a 90.</em>

2: Set up the equation.

<em>x + (3x + 10) = 90</em>

3: Combine like terms.

<em>4x + 10 = 90</em>

4: Solve for x.

<em>4x + 10 = 90</em>

<em>      -10 =   - 10</em>

<em>--------------------------</em>

<em>4x = 80</em>

<em>------------------</em>

<em>4          4</em>

What Is A Complex Sentence?

One independent clause and at least one dependent clause connected by subordinating conjunction make up a complex sentence. One of the four fundamental forms of sentences in the English language is complex sentences.

Complex sentences need a minimum of three components:

Independent Clauses: In writing, independent sentences are made up of the whole concepts stated along with a noun and verb (a subject and predicate). Independent clauses are capable of standing alone as whole sentences.

Dependent Clauses: Dependent clauses, also known as the subordinate clause, include a noun and a verb but are unable to articulate a coherent idea.

Subordinating conjunctions: Subordinating conjunctions are used to connect dependent clauses to independent clauses in complex sentences. These are the connecting words between the two clauses.

The ratio of money in Obi's wallet to Rudy's wallet one day was 5:2. Obi spent ?20 that day. Obi now had ?8 less than Rudy. How
BlackZzzverrR [31]

Answer:

  Altogether, they had ?28

Step-by-step explanation:

Had Obi spent only ?12, they would have been even. Thus ?12 is the same as 5-2 = 3 "ratio units". So, each "ratio unit" is worth ?12/3 = ?4.

Then Obi started the day with 5·4 = 20, and Obi started the day with 2·4 = 8. Obi ended with 0, which is 8 less than Rudy.

Altogether, they started with 20 + 8 = 28 of whatever a ? is.
