Y + 2 =1/2(x – 3). Please help ?!?

Mathematics

first, spread the parenthesis. y+2=1/2x-1.5

second, add 1.5 to both sides. y+3.5=1/2x

third, multiply by 2. 2y+7=x

if you are solving for y, do not do the third step, instead, subtract by 3.5. y=x-3.5

hope this helps!

ANSWER: x=2y+7 or y=x-3.5

Can someone tell me why the answer is 2?
Ira Lisetskai [31]

Answer:

If we put x=2 in the given equation, we get the answer for the equation as 2

Given:

      \sqrt{-3 x+10}=x

To find:

Why the answer is 2

Solution:

If we substitute the value x=2 in the given option, we get

        \sqrt{-3(2)+10}=2

          \sqrt{-6+10}=2

        \sqrt{4}=2

Result:

Thus we can say that when substitute the value of x=2

We get the answer as \sqrt{-3 x+10}=2

Explain how you could use either of two operation to solve exercise 10.

You want to know the factor by which 3 2/3 is multiplied to get 7 1/3.

1. You can estimate that it is 2 from 7/3 ≈ 2, then check by multiplication to see if that is right.
.. 2*(3 2/3) = 6 4/3 = 7 1/3 . . . . 2 is the correct factor.

2. You can divide 7 1/3 by 3 2/3 to see what the factor is.
.. (7 1/3)/(3 2/3) = (22/3)/(11/3) = 22/11 = 2 . . . . 2 is the factor Earl used.

3. You could see how many times you can subtract 3 2/3 from 7 1/3.
.. 7 1/3 -3 2/3 = (7 -3) +(1/3 -2/3) = 4 -1/3 = 3 2/3 . . . . . subtracting once gives 3 2/3
.. 3 2/3 -3 2/3 = 0 . . . . . . subtracting twice gives 0, so the factor is 2.

4. You could add 3 2/3 to see how many times it takes to get 7 1/3.
.. 3 2/3 +3 2/3 = (3 +3) +(2/3 +2/3) = 6 +4/3 = 7 1/3
We only need to add two values of 3 2/3 to get 7 1/3, so the factor is 2.
