The quotient of 4 and 5 is 4 divided by 5, which equals 0.8. The product of 6 and z is 6z. When the quotient of 4 and 5 (0.8) is added to the product of 6 and z (6z), the expression becomes 0.8 + 6z.
10 + 5x = 505x = 40x = 8

If the number is n, and the product is of the numbers p and q, the expression is p*q + (n + 15) : the parentheses are not necessary.
It is when the answer, when 2 things are multiplied, is the same as when they are added. For instance, 2*2=2+2
(4 x 4) + (2 x 5)
Thirteen grams of water is the same as thirteen milliliters. So, if thirteen grams of water were added to the beaker, then thirteen milliliters of water were added.

Someone needed something to fit in between 12 and 14. The number thirteen came about when people realized that something had to come between twelve and fourteen. When they added 3 + 10 or 8 + 5, they needed a number to result. Hence: thirteen.
The algebraic expression that represents the sum of 10 and 3 times a number x is 10 + 3x. This expression can be simplified by multiplying 3 with x to get 3x, and then adding 10 to it. In this expression, 3x represents three times the value of x, and 10 represents a constant value added to the product of 3 and x.
-5 x 3 + 2 = -13
