Joy organised a large wedding guests had to choose their meal from beef, chicken or vegetarian 1/3 of the guests chose beef 5/12 of the guests chose chicken 69 of the guests chose vegetarian how many guests were at the wedding

276 guests were at the wedding.

Step-by-step explanation:

Let x represent the number of guests that were at the wedding.

The guests had to choose their meal from beef,chicken or vegetarian.

1/3 of the guests chose beef. This means that the number of guests that chose beef is x/3.

If 5/12 of the guests chose chicken, it means that the number of guests that chose chicken is 5x/12. The total number of guests that chose beef and chicken is

x/3 + 5x/12 = 9x/12

The number of guests that chose vegetarian is

x - 9x/12 = 3x/12

69 of the guests chose vegetarian. This means that

3x/12 = 69

3x = 12 × 69 = 828

x = 828/3

x = 276 guests

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
