1) 3(2x + 10) = 54

Answers

Answer 1

Answer:

Answer:

x=4

Step-by-step explanation:

3(2x+10)=54

6x+30=54

6x=24

x=4

Answer 2

Answer:

Answer: 4

Step-by-step explanation:3(2x+10)=54

Multiply 3 to both numbers which would be 6x+30=54

Then, move 30 to the other side and that would be 6x=54-30

Subtract: 24 would be the answer

At last, you would divide 24 by 6

Just like this

x=24/6

Final answer would be

x=4

What is the answer to the equation 5x=2x+20?

Answers

I don't know. But I know how to find it. Let's work it out together:

5x = 2x + 20

Subtract 2x from each side: 3x = 20

Divide each side by 3 : x = 20/3 or ( 6 and 2/3 ).

$5x = 2x + 20 \n subtract--------\ \textgreater \ -2x \n 3x = 20 \n Divide -----\ \textgreater \ 3x \n \n x = 6 (2)/(3)$

You are going to a friend's house to watch a movie. If you drive on Street C, the distance is 3 miles. You need to stop at the movie store on Street A. The store is 1 mile from your house. What is the distance you will drive on Street B from the movie store to your friend's house? (right triangle)

Answers

Answer:

$√(10)$ miles

Step-by-step explanation:

In the figure, let P be yours house and Q be your's friend's house. Let R be the movie store.

Note that the distance from your house and to your house on Street C is 3 miles.

The distance from your house and to the move store on Street A is 1 mile.

Now, the distance from the move store to your friend's house is the hypotenuse of the right triangle ΔPQR.

The distance from the move store to your friend's house is RQ.

In the right triangle ΔPQR,

$RQ^(2) =PQ^(2) +PR^(2)$

= $3^(2) +1^(2)$

= 10

$RQ=√(10)$

Hence, the distance from the move store to your friend's house is $√(10)$ miles.

Answer:

2.83 miles

How can you write 72+(8+19) to make it easier to add?

Answers

First add up the numbers in the parentheses. 8+19, take that answer plus 71. When doing large questions like this I prefer to do things like this.
71
+ 27
_____

Take the ones column, adding it up, 1 plus 7, then put that 8 down here like this:
71
+ 27
_____
8
Then add add the other two, 7 plus 2 is 9. So you would end up with something like this:
71
+ 27
_____
98

Final answer:

To make 72+(8+19) easier to add, use the associative property to first add the numbers inside the parentheses, resulting in 72+27. Then add those two terms to get the sum, which is 99.

Explanation:

To write 72+(8+19) to make it easier to add, you can use the associative property of addition, which allows you to change the grouping of terms in the sum. The equation can be simplified by first adding the numbers in the parentheses. So, adding 8+19 gives us 27. Now, you can write the original expression as 72+27. This step simplifies the addition, allowing you to easily add 72 and 27 to get 99.

This is an example of the commutative property, A+B=B+A, which shows that the order in which you add numbers does not affect the sum. By rearranging the terms or grouping them differently as shown, the total sum remains the same. In this case, the expression has been simplified to make the addition easier to perform without changing the result.
