1) correctly translates the statement

First, "the sum of a number and four" is x+4.
Three times (x+4) is 3(x+4). It's also the left side of the equation.

Second, "five times the number" is 5x.
The result will then be "decreased by two", which is 5x-2. It's also the right side of the equation.

Therefore, option (1) is the correct answer.

Hope this would help :))

which expression is equivalent to the product 2x(x+2) (x-3)? A. 12x to the third - 12x ) B. 2x to the third - 4x squared - 6) C.

Law Incorporation [45]

Answer:

Option 4 is the correct option.

Step-by-step explanation:

We need to solve the expression 2x(x+2)(x-3)

Multiplying the terms with each other we get,

$2x(x+2)(x-3)\\=2x(x^2 -3x+2x-6)\\=2x(x^2 -x -6)\\=2x^3 -2x^2 -12x$

Option 4 is the correct option.

Mean Mode Median<br><br>12, 10 ,10, 13, 18, 9

Fiesta28 [93]

Mean: To find the mean you add all the numbers up and divide by the total number of factors.

12+10+10+13+18+9 = 72

72/6 = 12

Mode: To find the mode, we need to find the number that reoccurs the most in the sequence.

In this case it is 10 because it occurs twice, while the other factors occur once!

Median: To find median we need to arrange the numbers in numerical order. We then cross off one from each side until we come to the middle interger. If it comes between two numbers, you use the half way point between those two numbers.

9 10 10 12 13 18

In this case, we get left with 10 and 12. Meaning that our median is 11!

Jarvis has the following averages in his math

ollegr [7]

Answer:

≈77

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.

My answer:

Given:

Homework Avg: 93
Quiz Avg: 84
Test Avg: 72
Final Exam: 60

and weights Homework at 20%, Quizzes at 30%, Tests at 40%, and the final exam at 10%

=>Jason's class average is:

= 80*20% + 84*30%+74*40%+60*10%

= 80*0.2 + 84*0.3+74*0.4+60*0.1

= 76.8

≈77
