what is the answer to this equation

Answer:

The answer is A

Step-by-step explanation:

If you plug in the numbers it looks like this:

(A)  5(2) + 10(5) = 60

(B)  10(2) + 5(5) = 45

(C) 7(2) + 8(5) = 54

(D)  8(2) + 7(5)

so a is the only one that equals 60

She will sell 5 small shells and 10 large shells. The answer is A.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Sally is selling two types of seashells by the seashore. She is selling large and small shells. She sells small shells for 2 dollars each and large shells for 5 dollars each. She sold a combined 15 shells for a total of 60 dollars.

The numbers will be calculated as

(A)  5(2) + 10(5) = 60

(B)  10(2) + 5(5) = 45

(C) 7(2) + 8(5) = 54

(D)  8(2) + 7(5)

Here, option A is giving the correct sum. Therefore, she will sell 5 small shells and 10 large shells.

12x-5=-60

The area of the given parallelogram with a base of 12 cm and a height of 9 cm is 108 cm². The area is obtained by multiplying the base and height.

To find the area of a parallelogram, the formula that should be used is A = b × h, where b is the base and h is the height. Since a parallelogram has two pairs of parallel sides, either of the two parallel sides can be chosen as the base. The height is the perpendicular distance between the base and the opposite side.

In the given parallelogram, the base is 12 cm since it is one of the parallel sides. The height, on the other hand, is 9 cm since it is the perpendicular distance between the base and the opposite side. Therefore, the area of the parallelogram is: A = b × h = 12 cm × 9 cm = 108 cm²

Thus, the area of the parallelogram is 108 cm². It is important to note that the unit of the area is always squared since the area is calculated by multiplying two lengths together.

Answer:

C. mass of reactants = mass of products

Step-by-step explanation:

The mass of products = mass of reactants

This question asks us about the law of conservation of mass

The law of conservation of mass states that matter can neither be created nor destroyed but can be transformed form one state or form to another. This is the basics of science which implies that whatever matter we have, it was created from something before it was converted into what we have at the moment.

However, this law does not hold nuclear reactions because they undergo changes in the core of the matter which can change the proton of that same matter or neutron from one element to another. This is to say that in nuclear reactions, matter can be created and it can also be destroyed.

The answer to this problem is mass of products = mass of reactants.

Answer:    j = 3d + 4

======================================================

Explanation:

Referring to the answer above, the "+4" at the end represents the amount Desmond already has. He started off with 4 liters.

The 3d represents the 3 liters he gets per day, where d is the number of days.

So we combine the two elements getting 3d+4 representing the number of liters at any given day. That's why the answer is j = 3d+4

If we plug in d = 0, then j = 3d+4 = 3*0+4 = 4 liters is what he starts with.

If we plug in d = 1, then j = 3d+4 = 3*1+4 = 7 liters is what he has the following day. This shows Desmond gained 3 more liters.

If you plug in d = 2, you'll find that 3d+4 becomes 10, showing yet another 3 liters is added on. This process can go on for as long as you want.
