For what values a is the equation (1/a+2)=(1/a)+(1/2) true?

Answers

Answer 1

Answer: There is no value of 'a' that makes the equation true.
In other words, the equation has no solution.

Here's how you can tell:

(1/a + 2) = (1/a) + (1/2)

Eliminate parentheses: 1/a + 2 = 1/a + 1/2

Subtract 1/a from
each side: 2 = 1/2

Is there any value of 'a' that can make 2 = 1/2 ?
I can't think of one.
So the equation has no solution.

Complete the factor 2x^+8x+6

Answers

Answer:

the completed factor is (2x + 2)(x + 3).

Step-by-step explanation:

To complete the given factor, we need to find two binomials that multiply together to give us the expression 2x^2 + 8x + 6.

First, let's look at the coefficient of x^2, which is 2. The only way to factor 2x^2 is as 2x * x.

Next, let's look at the constant term, which is 6. We need to find two numbers that multiply to give us 6 and also add up to the coefficient of x, which is 8. The numbers that satisfy this condition are 2 and 3.

Therefore, the factors of 2x^2 + 8x + 6 are:

(2x + 2)(x + 3)

You can verify this by multiplying the two binomials together using the distributive property.

So, the completed factor is (2x + 2)(x + 3).

To solve for $(1)/(2)- (1)/(10)$ You first need to find a common denominator.

To do so, you need to make both denominators 10 by multiplying the top and bottom of $(1)/(2)$ by 5

$(5)/(10)- (1)/(10)$ = $(4)/(10)$ Reduce by dividing both the top and bottom by 2

Your answer is $(2)/(5)$

Laurie was scuba diving. Each time she dove 5 feet deeper, she would stop and clear her ears. After Laurie had checked her instruments 3 times, she was at her maximum depth of 60 feet. Which expression best represents Laurie's maximum depth? (4) (negative 5) (3) (Negative 4) (Negative 5) (Negative 3) (Negative 5) (20) (3) (Negative 5) (Negative 20) (Negative 3)

Answers

Complete question :

Answer:

(-5) * (20) * (3)

Step-by-step explanation:

Diving 5 feets deeper = descent = negative 5 Feets

Each time instrument is checked = (60/3) = depth of 20 feets

Number of times instrument is checked = 3

Hence, maximum depth :

Diving 5 feets deeper * Each time instrument is checked = depth of 20 feets * Number of times instrument is checked

(-5) * (20) * (3) = - 60
