Answer:

2x - 6

Step-by-step explanation:

In this question, you have to simplify the expression.

Solve:

(3х - 5) - (5х + 1)

Distribute the negative sign the variables inside the parenthesis.

3x - 5 - 5x - 1

Combine like terms.

3x - 5 - 5x - 1

-2x - 5 - 1

-2x - 6

Your final answer would be -2x - 6

If you currently have $300 set aside for the trip and you're only able to save $75 a week, write an inequality representing how

algol13

Answer:

see the explanation

Step-by-step explanation:

In this problem

I will assume that the total amount required for the trip is $1,200

Let

x ----> the number of weeks

we know that

The number of weeks multiplied by $75 plus $300 must be at least $1,200

In this context, the term "at least" means "greater than or equal to"

The linear inequality that represent this problem is

$75x+300\geq 1,200$

Solve for x

subtract 300 both sides

$75x\geq 1,200-300$

$75x\geq 900$

Divide by 75 both sides

$x\geq 12\ weeks$

therefore

The minimum number of weeks you need to save is 12

Brian correctly use a method of completing the square to solve the equation X a 2nd plus 7X -11 equals zero Brian‘s first step w

ArbitrLikvidat [17]

Answer:

$(\frac{7}{2})^{2}$

Step-by-step explanation:

Brain correctly use a method of completing the square to solve the equation:

$x^2+7x-11=0$

His First Step is to: Take the Constant Term to the Right Hand Side

$x^2+7x=11$

The Next Step Would be to:

Divide the Coefficient of x by 2
Square It
Add it to both Sides

In this case, the Coefficient of x = 7

Divided by 2 = $\frac{7}{2}$

Squaring It, we have: $(\frac{7}{2})^{2}$

It is this number $(\frac{7}{2})^{2}$ that is added to both sides in the manner below:

$x^2+7x+(\frac{7}{2})^{2}=11+(\frac{7}{2})^{2}$

Answer:

Step-by-step explanation:

Solve 5 to the power of x minus 3 to the power of x when x=2.

So, you do 5 to the power of 2 minus 3 to the power of 2, which is 25-9=16
