1. A calamansi juice (c) and a slice of buko pie (
b) cost at most P60. A slice of buko pie's price is
at most 5 times the price of a calamansi juice.
2. A group of tourists is planning a trip to Boracay
this December. At least 12 people must sign up for
the trip, or it will be cancelled. The number of boys
(x) in the group is at most twice the number of girls

Php100 a day.
4. A house (h) and lot (/together in a subdivision

this doesn't make sense lol

students group

step-by-step explanation:

a person who   joins a party or a seminar can explain his feelings about that particular occasion better more than anyone else.

as bella managed a show for the students in the school and invited students to watch that show

hence

students group will be the best group to survey to find this information

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)
