PLZ HELP 1.Which expression is equivalent to 3 x – 3 y?

2.Rashad solved the inequality 74x10 and determined that 7x5 could equal 6. Is Rashad correct?

3.What values of 7x5 satisfy this inequality 74x9?

Expression 3x - 3y = 3 (x - y)

Step-by-step explanation:

Expression equal to 3x - 3y = 3 (x-y)

- By taking 3 common from the equation

Eg : If x = 5 , y = 3

3x - 3y = 3 (5) - 3 (3) = 15 - 9 = 6

3 (x - y) = 3 ( 5 - 3 ) = 3 (2) = 6

As both above are equal, the expression equivalency is hence proven .

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
