Carmina bought 20 pizzas for her party an hour after the party started 2/7 of the pizzas had been eaten how many pizzas have been eaten make an equation to solve a word problem.

pizzas eaten =2/7 x 20

5 5/7 pizzas have been eaten

Step-by-step explanation:

pizzas eaten = 2/7 x 20

40 / 7 = 5 5/7

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)
