To calculate the sum of the products of 4 and 3, and 1 and 1, you first find the products: (4 \times 3 = 12) and (1 \times 1 = 1). Then, you add these two products together: (12 + 1 = 13). Therefore, the correct answer is 13.
n = number 2(n + 15) ======
The sum of ( d ) and 9 can be written as the expression ( d + 9 ).
In a mathematical expression, a sum is typically represented by the addition operator, which is the plus sign (+). For instance, in the expression (a + b), the terms (a) and (b) are being added together, indicating that this part of the expression represents a sum. Any grouping of terms connected by the plus sign constitutes a sum.
The sum of n and 5 is n+ 5
There is a calculation error.
reactants -----> products is correct
n = number 2(n + 15) ======
a sum
A sum has to include two or more numbers in the calculation.
Maya wrote the expression 3+5+4.5 to represent the total distance that she traveled. Which statement best describes Maya's expression? Maya's expression will generate the correct sum because of the associative property.
The correct way to write a chemical equation is: Reactants -> Products. This means that the reactants on the left side of the arrow are converted into products on the right side. The double arrow symbol <=> can be used to indicate that the reaction can proceed in both directions to reach an equilibrium.
The sum of n and 5 is n+ 5
The molar mass of a compound is the sum of atomic weights of the contained elements in the molecule.The expression atomic weight is correct for elements; for isotopes is correct atomic mass.
There is a calculation error.
This is called the "distributive property" and has applications in algebra.
C12H18O2 is not a mathematical expression, not is it a sum so there is no sensible answer possible.
The algebraic expression for the sum of 11 times 5 and three is 11s+3
