9/10 divided by (-3/5)

Mathematics
1 answer:
katrin [286]3 years ago
4 0

Answer:

-\frac{3}{2} OR (-1.5)

Step-by-step explanation:

Apply the fraction rule: \frac{a}{-b} =-\frac{a}{b} (means just flip!)

Divide using the rule: \frac{a*d}{b*c}

By then you should have: -\frac{45}{30}

Just simplify.

Cindy's age, x, is 3 times her age 6 years ago which equation represents the statement x=3(x-6) or x=3-6x or x=3x-6 or x=3x+6
WINSTONCH [101]
Let's denote Cindy's age which is unknown with X
We know that Cindy's age is 3 times her age 6 years ago. 
6 years ago Cindy's age was the present age (X) - 6 : X-6
The fact that the  present age is 3 times her age 6 year ago can be written as:
3*(X-6)
So, finally:
X=3*(X-6)
