it the tenths I think.....
W=20.3
solve what's in the parenthesis, move the terms, calculate, then divide both sides.
Answer:
Step-by-step explanation:
If you have written g(x) correctly then g(-5) = 3.40 - 8 = -4.6
If you meant to write g(x) = 3.40x - 8, then g(-5) = -25
5x+2y=20
Substitute 0.3 for x
5(0.3)+2y=20
Multiply 5 by 0.3
1.5+2y=20
Subtract 1.5 from both sides
2y=18.5
Divide 2 on both sides
Final Answer: y= 9.25
