What is the value of a in the algebraic expression (5a+3)=52

a= 49/5 or 9.8

Step-by-step explanation:

49 / 5 ( or ) 9.8

Step-by-step explanation:

( 5a + 3 ) = 52

 5a + 3 = 52

 5a = 52 - 3

 5a = 49

   a = 49 / 5

       ( or )

   a = 9.8

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
