Simplify the expression by combining like terms: x + 7x

Answers

Answer 1

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

Step-by-step explanation:

Answer 2

Answer:

[tex]8x[/tex]

Step-by-step explanation:

[tex]x+7x[/tex]

[tex]8x[/tex]

The answer is [tex]8x[/tex] when you simplify because you are adding another [tex]x[/tex] to [tex]7x[/tex] so it becomes [tex]8x[/tex]

Multiply the first number by its reciprocal

try to explain in the most easiest way as possible plz and thank you ​

Answers

Answer:

when we multiply a number by its reciprocal we get-

For example- 2/1 × 1/2 = 1 . Every number has a reciprocal except 0 (1/0 is undefined)

Answer box1 : 42
Answer box2 : 1

I always remember REciprocal = REverse the fraction. So the of 6/7 is going to be 7/6 and so on.

Now you can just think of it like regular multiplication. You can spilt it into 2 problems (top and bottom)

6 x 7 = 42
7 x 6 = 42

Any number over itself always equals 1, so that means anytime you multiply a fraction by its own reciprocal, your answer will always be 1

The net below has dimensions l = 14 feet, w = 7 feet, and h = 13 feet. How will the surface area of the figure change if the width decreases by 2 feet?

Answers

Step-by-step explanation:

So, we know that the width in this image has a length of 7 feet. decreasing it by two will give us 5 feet. Now, we can solve the surface area.

Lateral faces: 7 x 14 x 4 = 392

Bases: 14 x 13 x 2 = 364

Add them all up, and we get 756 ft²

856 should be the answer

Answer:

(you'll have to read the explanation)

Step-by-step explanation:

There are 8 lines from 1 to 2, so plotting 1 1/2 (or 1.5) is right in between. I'm not sure how to add the picture back into the explanation, but I will try my best to explain. You want to plot your point for 1 1/2 4 lines after the 1. For the 2 1/4, you want to plot your point on the second line from the 2. Let me know if it doesn't make sense!

Answer: See the attached image below

1 1/2 is located at the exact midpoint between 1 and 2.

2 1/4 is located 2 tickmarks to the right of 2.

===================================================

Explanation:

Think of 1/2 as 4/8

The number 1 1/2 is the same as 1 4/8

So we start at 1 and move 4 tickmarks to the right to get at the exact midpoint (note there are 8 tickmarked spaces between any two whole numbers).

This places us exactly at the midpoint between 1 and 2.

-----------------

To plot 2 1/4, we will effectively plot 2 2/8 since 1/4 = 2/8

We start at 2 and then move 2 tickmarks to the right to arrive at 2 2/8

Then in the top row, there's a penny and a nickel. So that's an extra 1+5 = 6 cents.

Overall, the total value is 60+6 = 66 cents

Note: 66 cents converts to $0.66 or you can say 0.66 dollars.
