Ok, so the first thing you should do is collect like-terms.


7x+3+6x+11

Combine 7x and 6x ---> You'll get 13x.


So it'll be 13x + 3 + 11

Now you'll combine 3 + 11 and you'll get 14.

The answer should be 13x + 14


I hope this helped ^^*

Combine like terms.

Since 7x and 6x both have a variable of x, you can combine them.

7x + 6x = 13x

After that, you are left with:

13x + 11 + 3

You also have two numbers without variables; 11 and 3. You can also combine those.

11 + 3 = 14

So, your final answer would be:

13x + 14

Mary can type six letters in 20 minutes, Maggie can type five letters in 20 minutes, and Su Ying can type two letters in 20 minu
marin [14]

Answer:

70 minutes

Step-by-step explanation:

Mary can type the number of letters in 20 minutes = 6

Maggie can type the number of letters in 20 minutes = 5

Su Ying can type the number of letters in 20 minutes = 2

Working together they can type the number of letters in 20 minutes

= 6 + 5 + 2

= 13 letters

Working together they can type the number of letters in 1 minute = \frac{13}{20}

To type 45 letters time taken by them = \frac{45}{\frac{13}{20} }

                                                               = 45\times \frac{20}{13}

                                                               = \frac{900}{13}

                                                               = 69.230 ≈ 70 minutes

It will take them 70 minutes to type 45 letters.

Question 16. I need to know how to do this problem because I have a math final tmr!

A ratio shows us the number of times a number contains another number. Monique should choose the third option.

<h3>What is a Ratio?</h3>

A ratio shows us the number of times a number contains another number.

Given Monique prefers the ratio of multiple-choice questions to essay questions to be 4:1, Therefore, we can write,

Multiple choice questions/ essay questions = 4/1,

If we multiply both the numerator and the denominator by 6, the ratio will be,

Multiple choice questions/ essay questions = 4/1 × 1

Multiple choice questions/ essay questions = (4/1) × (6/6)

Multiple choice questions/ essay questions = 24 / 6

Thus, Monique should choose the third option.
