Kris has $19. she wants to buy a bat for$85. she can earn $11 for each lawn she mows.

what is the number of lawns (n) kris could mow to earn at least enough money to buy the bat.

hints:

kris has 19

11n for each lawn

at least means > or = to 85

(a.) 19 + 11n ≥ 85

(b.) 15 + 4n ≥ 85

(c.) 111 + 90n ≥ 85

(d.) 17 + 1n ≥ 85

answer:

3 bags of apples and 2 bags of oranges.

step-by-step explanation:

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)

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)
