Answer:
The first operation is to add, and you are adding 3 to both sides of the equation to isolate the x.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. You are solving for the variable, x, when solving this equation.
Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction

The first step is to add 3 to both sides of the equation:
(x/3) - 3 (+3) = 11 (+3)
(x/3) = 11 + 3
(x/3) = 14
The second step is to multiply 3 to both sides of the equation:
(x/3) * 3 = (14) * 3
x = 14 * 3
x = 42
42 would be your final answer.

All you have to do for this one is 650 divided by 76 which is 8 but it won't go into it evenly
Answer:
Original rectangle: Since the area of a rectangle is the length * width, the area of this rectangle is 7 * 2 = 14 square cm.
New rectangle: The new dimensions of this are 7*3 = 21 cm by 2*3 = 6 cm. To find the area, we multiply these two together. 21*6 = 126 square cm.
126 is 9 times greater than 14, so the area will be multiplied by 9.
