Explain how you would subtract -4/5 from 9/10 .

-17/10

Step-by-step explanation:

you have to find a common denomentaor first wich would be 10

then you have to mutiply -4/5 by 2 which would be -8/10

and then you would do regular subtraction

but since its a negative number your gonna actually add but then the final answer will be negative

-17/10

hope this helps I really suck with fractions

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
