Mary, Hans, and Alan have a total of $54 in their wallets. Mary has $10 more than Hans. Alan has 2 times what Mary has. How much do they have in their
wallets?

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

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)

y=-2x+1500

step-by-step explanation:

+1500

2 over one
