Choose the arithmetic series that is associated with this summation.

Answers

Answer 1

Answer: Plug n = 1 into the expression 20-9n and we get
20-9n = 20-9*1 = 20-9 = 11

So 11 is the first term of the series that we add up. Therefore the answer must be choice C, which has 11 listed as the first term added

A bag of chips costs $3.79 including tax Mr.Connor wants to purchase chips for his class and has a $15 budget. Write and inequality to solve for the number of bags of chips Mr.Connor can purchase with his budget A. $15x > $3.79 B.$15x < $3.79 C $3.79 > $15 D. $3.79 < $15 (There is a flat line under all the greater than and less than signs)

Answers

The inequality equation that could best express the statement will be letter d. 3.79x < 15. This is because there is only 15 budget from Mr. Connor, and his spending must not exceed the budget. Then the price per pack is 3.79, so it is express as 3.79x.

Answer:

D. $3.79x\leq 15$

Step-by-step explanation:

We are given that

Cost of one bag of chips including tax=$3.79

Mr.Connor has budget=$15

We have to write an equality to solve for the number of bags of chips can purchased by Mr.Connor with his budget.

Let x be the number of bags of chips

According to question

$3.79x\leq 15$

Hence, option D is true.

Answer:D. $3.79x\leq 15$
