x = -4 3/5
y=2 1/3
Step-by-step explanation:
you need to get these variables alone on each side to find the answer.
Earth rotates one full rotation a day
So
It rotates 1° in
It rotates 150° in
Answer:
140%
Step-by-step explanation:
So a fraction can be expressed as: and if a number decreases by x%, the new number is (100-x)% the original value. So since the numerator decreases by 30%, it's not 70% the original value, and it's very similar with the denominator, with it only retaining 50% of it's original value. This gives you the formula: . You can rewrite the fraction as: in doing so it's easy to see that you can cancel out the 0.5 and get: . This means the value is increasing by 1.4 or 140%
