Answer:
X is equal to 20
Step-by-step explanation:
Angles of a triangle equal 180.
110+x+x+30=180
2x+140=180
2x=40
x=20
If you input 20 as X back into the equation, then you can check that it is the right answer.
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! :)
When you subtract them you get the answer 57.99
My answer is 16 cause if you add 10 and 3 and 3 the =16
