.75x-20= 620 what does x equal rounded to the nearest 100?

vodomira [7]

To solve this, we’ll have to use inverse operations.

Since addition is the inverse to subtraction, we’ll add 20 to 620.

20 + 620 = 640

From there, since division is the inverse of multiplication, we’ll divide .75 by 640.

640/.75 = 853.33333 repeating. We can round this to 853.33, to round to the nearest hundredth.

Therefore, 853.33 would be your answer! You can check this by solving the equation forwards (853.33 x .75 = ~640, 640 - 20 = 620.)

Hope this helps! :)

Find and correct the error of the following factor.

pshichka [43]

3x² + xy2 – 3xy-y? >> 3x² - xy - y

line 1: = (3x² + xy2)+(-3xy – y?)

ANS 3x² - xy - y 《Correct》

line 2: = x(3x + y2) - y(3x – y2)

ANS 3x² - xy +2y²

line 3: = (x-y) (3x +y?)

ANS 3x² - 2xy - y²

If it incorrect, I'm sorry.
