Answer 2

Answer: Hello.
2.7(6.2)= 16.74
-9.3(1.2)=11.16
6.2(9.3)=57.66
1.2(2.7)=3.24

Complete the standard form of the equation –4y = 3 – 2x.

Answers

Ax + By = C is the standard form. Try to see how - 4y = 3 - 2x can fit into Ax + By = C.

Add 2x on both sides to make the x variable present on the other side of the equation.
Now we get
2x - 4y = 3.

A is 2 since that is the number which precedes x.
B is -4 since that is the number which precedes y.
C is 3.
So - 4y = 3 - 2x in standard form would be 2x - 4y = 3.

Translate this phrase into an algebraic expression. 4 inches more than twice Julie’s height. Use the variable x to represent Julie’s height

Answers

The algebraic expression for "4 inches more than twice Julie’s height" is 2x + 4, where "x" represents Julie's height in inches.

To translate the phrase "4 inches more than twice Julie’s height" into an algebraic expression, we use the variable "x" to represent Julie’s height.

Represent Julie's height with the variable "x".

Twice Julie's height is 2 times "x", which can be expressed as 2x.

Add "4 inches more" to the twice Julie's height, resulting in 2x + 4.

The final algebraic expression is 2x + 4, which represents "4 inches more than twice Julie’s height" in terms of the variable "x."

For example, if Julie's height is 5 inches (x = 5), the expression evaluates to 2(5) + 4 = 14, meaning she is 14 inches tall in this context.
