Answer:
Melissa wrapped 5 pounds of fudge
Step-by-step explanation:
This is the correct question
Melinda donated fudge for the school bake sale. she wrapped 80 pieces of fudge. each piece of fudge weighed 1 ounce. how many pounds of fudge did melinda wrap?
In this question, we are asked to calculate the pounds of fudge wrapped by Melinda.
Firstly, we need to calculate the total weight of the fudge wrapped by Melinda in pounds.
From the question , we can identify that she wrapped 80 fudge with each of the fudge weighing 1 ounce each.
The total weight of all the fudge wrapped in ounces would be 80 * 1 = 80 ounces
Now, let’s convert this weight in ounces to pounds.
Mathematically, there are 16 ounces in a pound.
Hence, the weight in pounds of 80 ounces would be; 80/16 = 5 pounds

Step-by-step explanation:
in order to evaluate for the value of x from this 2(x+5)=7x-5 , we will open the bracket and the evaluate for x.
solution
2(x+5)=7x-5
2x + 10 = 7x - 5
collect the like terms together
2x + 10 +5 = 7x
15 = 7x - 2x
15 = 5x
divide both sides by 5
15/5 = 5x/5
3 = x
x =3
so, to evaluate for 2x² + 10
will be
2x² + 10
2 (3)² + 10
2 x 9 + 10
18 + 10
28
Using division and the graph, the zeroes of the function are given as follows:
- x = -1 with multiplicity 2.
- x = 2/3 with multiplicity 1.
<h3>How do we find all the zeros of the function?</h3>
The function in this problem is defined as follows:
f(x) = -3x³ -4x² + x + 2.
From the graph, we have that x = -1 is a zero of the function, meaning that it can be written as follows:
-3x³ -4x² + x + 2 = (x + 1)(ax² + bx + c).
The other zeros will be the zeros of ax² + bx + c. To find the coefficients, we use a system of equations, hence:
(x + 1)(ax² + bx + c) = -3x³ -4x² + x + 2
ax³ + (a + b)x² + (c + b)x + c = 2.
Hence the coefficients are given by:
Thus the quadratic equation that we have to solve is:
-3x² - x + 2 = 0
3x² + x - 2 = 0.
Hence:
The zeroes of the function are given as follows:
- x = -1 with multiplicity 2.
- x = 2/3 with multiplicity 1.
