Answer:
(3/4 * 12a) + (3/4 * 8) = 31.2
a = 2.8
Step-by-step explanation:
[tex](\frac{3}{4}*-)+(-*8)=-[/tex]
[tex]\frac{3}{4} (12a + 8) = 31.2\\\\\frac{3}{4} (12a)+\frac{3}{4} (8)=31.2\\\\9a+6=31.2\\\\\ \ \ -6 \ \ \ \ \ \ \ \ -6\\\\9a = 25.2\\\\/9 \ \ \ \ \ /9\\\\a=2.8[/tex]
Answer:
(3/4 * 12a) + (3/4 * 8) = 31.2
a = 2.8
Hope this helps!
