Kara has five exam scores of 63 59 67 75 and 73 in her biology class what score does she need on the final exam to have a mean grade of 70?

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

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.

thats not a system of equations, that is a solution
