Joe buys candy that costs $7 per pound. He will spend at least $56 on candy. What are the possible numbers of pounds he will buy?

8 pounds(lbs)

Step-by-step explanation:

If a candy costs $7 per pound, $56 divided by $7 will equal 8 pounds.

8 ≤ x pounds

Step-by-step explanation:

I will be using * as a symbol for multiplication.

We can create an inequality for this question.

x will represent the amount of pounds that he may buy.

56 ≤ 7 * x

(This means that 56 is less than or equal to 7 times x.)

We create this inequality because of how Joe will spend AT LEAST $56 dollars on candy. The amount of candy is not defined in the question.

Let's solve.

56 ≤ 7 * x

Divide by 7.

8 ≤ x

Joe will buy at least 8 pounds of candy,

Note the word at least. This states that he may buy more, however 8 is the minimal amount he will obtain.

Please inform me of any mistakes.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
