Which two operations are needed to write the expression that represents "eight more than the product of a number and two"?
multiplication and subtraction
division and subtraction
multiplication and addition
division and addition

For this case we must represent the following expression algebraically:

"eight more than the product of a number and two"

Let "x" be the variable that represents the unknown number

We have to:

the product of a number and two is represented as:

Then, the full expression will be:

Thus, we use multiplication and addition.

Option C

multiplication and addition

Step-by-step explanation:

In mathematics we use addition(+) operation to show "sum", subtraction (-) to show "difference" , multiplication (×) operation to show "product" and divide (÷) to show "quotient".

Given mathematical statement : eight more than the product of a number and two

Here, we use addition(+) operation to show "more than" and multiplication (×) operation to show "product" .

Hence, the two operations are needed to write the expression that represents are : multiplication and addition

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
