Variable c is 5 more than variable a. variable c is also 3 less than variable a. which pair of equations best models the relationship between c and a?

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

1.two more than the quotient of a number and 6 is equal to 7 use the c for the unknown number translate the sentence into an equation

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
