5. The steps for solving the equation 3x + 13 = x + 27 are shown below. What property justifiesthe second step in the solution?
(1 point)
3x+13 = x+27
Step 1: -x - x
2x+13=
2x+13 = 27
Step 2: 1-13 -13
= 14
14
Step 3: 2
2
O additive identity
O additive inverse
O substitution
O subtraction property of equality

Answers

Answer 1
Answer:

Answer:

D. Subtraction property of equality.

Step-by-step explanation:

We have been given an equation 3x+13=x+27. We are asked the property used in the second step of equation to solve it.

Step 1:

3x+13=x+27

Step 2:

3x-x+13=x-x+27

We can see that x is subtracted from both sides of equation.

We know that subtracting same quantity from both sides of equation is known as subtraction property of equality.

Therefore, option D is the correct choice.
Answer 2
Answer:

Answer:

In step 2 we applied the subtraction property of equality

Step-by-step explanation:

The subtraction property of equality tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.

In step 2 we did that:

2x + 13 - 13 = 2x + 27 - 13

(2x + 0 = 2x + 14)

2x = 2x + 14

A plane flew 1,000 miles away from London for one flight. For the next flight, it flew 500 miles toward London. How far was the plane from London after the second flight?

Answers

So, It First Flew 1000 Miles Away. So, It Is Positive 1000 Miles. Now, It Flew 500 Miles Closer, So Negative (closer) Distance. So, Add. 1000+(-500)
Adding Negative Is The Same As Subtracting So, 1000-500 = The Distance.
So, The Distance Away Is 500 Miles. 

Answer:

500 miles

41.77=r^3 find the original equation is 175=4/3 (pie) r^3

Answers

Hello!

I am assuming we want to find r. To do so we just find the cube root of 41.77, which is about 3.47.

Therefore, r is about 3.47.

I hope this helps!

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

Number = 5.7935

Now,

To round 6.4578 to the nearest thousandth, you look at the digit 7 in the ten-thousandth place. Since 7 is more than 5, you round up by adding 1 to the digit 8 in the thousandth place and dropping the digit 7.

Therefore, by algebra the answer will be 6.458.
