Step-by-step explanation:
5x+3x=12+4
8x=16
x=16÷8
x=2
9=3^2
3^(2x)=(3^2)^(3x-4)
3^(2x)=3^(6x-8)
2x=6x-8
0=4x-8
8=4x
2=x
7x-x=19-7
6x=12
x=2
Ask me if you have a question. Glad to help!! :))
Step 1: Simplify 0.02 x 0.789 to 0.01578
0.01578 ÷ 3.0999
Step 2: Simplify 0.01578 ÷ 3.0999 to 0.0051
0.0051
Done! :) Decimal Form Would Be 0.0051
