Explain how you could add 678 + 303 using mental math

Answers

Answer 1

Answer: 678 + 303 = 981

Here are a few examples to get you started:
600 + 300 = 900
78 + 3 = 81
900 + 81 = 981
Here's another one:
678 = 600 + 70 + 8
303 = 300 + 00 + 3
Add the ones place = 11
Add the tens place = 70
Add the hundreds place = 900
Now add 900 + 70 + 11 = 981
Hope this helps! :-)

Hope this helps.

Answer:

7p-3

Step-by-step explanation:

We are given the expression:

8p - 3 + 9p + 6p + 2p - 6p - 3p - 9p

To simplify, we can combine like terms. Add all the terms with a variable, then add the terms without a variable.

(8p + 9p + 6p + 2p - 6p - 3p - 9p)+ -3

(25p -18p) -3

7p-3

Solve the proportion 8/3=g/3 ... A.1/8 B.9/8 C.8 OR D.8/9

Answers

Answer:

g = 8. (Answer C)

Step-by-step explanation:

We are given 8/3 = g/3.

If we multiply both sides by 3, this will eliminate the fractions, and we will be left with g = 8. (Answer C).

Final answer:

The solution to the proportion 8/3 = g/3 is g = 8, corresponding to option C.

Explanation:

In this proportion, the value of g can be found by solving the equation 8/3 = g/3. Because both sides of the equation are divided by 3, the 3's essentially cancel each other out, leaving you with g = 8.

Therefore, the solution to the proportion 8/3 = g/3 is g = 8. So, the correct answer is C. 8.

How do I do this?
4/5x>14

Answers

Well, first, you need to know what you want to 'do' to it.

You want to find the description of what 'x' has to be in order to
make that inequality a true statement. Here's one way to do it:

      4/5 x > 14

Multiply each side by 5 :   4    x > 70

Divide each side by 4 :    x > 17.5 .

That's it. As long as 'x' is more than 17.5 ,
the original inequality is true.
