Algebraic expressions from word problems Grace wants to divide the job of writing x invitations to the party equally among 4 committee members.
Write an expression to determine the number of invitations she will have each committee member write.
If there are 120 invitations to write, how many will each of the committee members write?

answer: 298143

step-by-step explanation:

the 4th choice is the correct one

step-by-step explanation:

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3

hello, it is c -4

hope i you have a good day
