Answer:

  • \Large\boxed{\sf{9x+11}}

Step-by-step explanation:

<u>Given:</u>

Isolate the term of x from one side of the equation.

Use the distributive property.

<u>DISTRIBUTIVE PROPERTY:</u>

\Longrightarrow: \sf{A(B+C)=AB+AC}

Each term within the parentheses can be multiplied by a factor outside the parentheses.

3(x+1)

3*x=3x

3*1=3

<u>Rewrite the expression down.</u>

3x+3

3x+3+2(3x+4)

<u>Multiply expand.</u>

2(3x+4)

2*3x=6x

2*4=8

6x+8

3x+3+6x+8

<u>Combine like terms.</u>

3x+6x+3+8

<u>Add the numbers from left to right.</u>

3+8=11

3x+6x+11

<u>Add.</u>

<u>Solutions:</u>

3x+6x=9x

\Longrightarrow: \boxed{\sf{9x+11}}

  • <u>Therefore, the final answer is 9x+11.</u>

I hope this helps. Let me know if you have any questions.

For a Valentine's Day dance, tickets for couples cost $12 and tickets for individuals cost $8. Suppose 250 students attended the
lakkis [162]

Answer: 105 couple tickets and 40 individual tickets

For this I will use the "Graphing Method"

     First, we need to set up two equations.

-> Let x be the number of couple tickets.

-> Let y be the number of individual tickets.

-> It is "2x" because a couple means two.

     $12x + $8y = $1,580

     2x + y = 250

     Next, we will graph this.

-> The point at which the two lines intersect is our solution.

-> See attached.

-> x = 105, so 105 couple tickets

-> y = 40, so 40 individual tickets

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

For part A the choices are 25 and 34 and for part b it is 2 and 10
diamong [38]

Answer:

Part A is 34

Part B is 2

Step-by-step explanation:

This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.

To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.

10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.
