7. Melissa wants the city to provide every Farrington classroom with recycling bins and is in the process of
collecting student signatures for her petition. So far
Melissa has collected 82 signatures and wants to
collect 15 signatures for each classroom she visits
during advisory time. If S is the total number of
signatures Melissa has collected, and C is the number
of classroom visited, write an equation.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

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.
