2,000 + 400 + 70 would equal 2,470.

The correct way to write it would be 2,000 + 400 + 7

Felix's error is that he added the numbers incorrectly.

Felix got the answer 2,407 by adding 2,000 + 400 + 7, but the problem states to add 2,000 + 400 + 70. In return, by adding in the correct way like the question have stated you should get 2,470

Which value of x satisfies the equation |-2x|=10
uranmaximum [27]

Answer:

Step-by-step explanation:

First you will divide I-2xI on both sides that should look like this:

       -2x/-2 = 10/-2

when you divide it your -2‘s should cancel out and you should be left with

         -x=10/-2

when You divide 10/-2 you should get -5

         10/-2= -5

your answer should look like this then

         -x=-5

-5 is just one of your answers the other is 5

To get rid of the negative on the -X you have to didvide it by both sides

        -x/-x=-5/-x

your answer should be

          X= 5

your final answers are

      -5 or 5

Translate each sentence into an equation.
ser-zykov [4K]
Bear in mind that words like "are" or "is" is replaced by an equal "=" sign in the equation.
more than or increased by denotes addition
twice the number denotes two times the number
times, simply means multiply.

Let x be the unknown number in the equations.

12 birds are 3 more than twice the number of birds Rhonda saw yesterday.

12 = 2x + 3

Negative 6 times the sum of a number and 4 is 2

-6(x+4) = 2

Four time a number increased by 3 is -89

4x + 3 = -89

Hope this helps!
