Watermelons cost $0.35 per pound. joseph’s watermelon costs between $4.20 and $5.25. which compound inequality correctly represents the possible weights of his watermelon

Step-by-step explanation:

We are given that

Cost of 1 pound watermelon=$0.35

Joseph's watermelon costs between $4.20 and $5.25

We have to find that the inequality which represents the possible weight of his watermelon.

Let x be the number of pounds of watermelon.

According to question information

Taking first inequality equation

Divide by 0.35 on both sides then we get

Now, taking second inequality equation

Divide by 0.35 on both sides

From first inequality and second inequality equation then, we get

Hence, the inequality that represents the possible weights of his watermelon is given by

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
