Vivian charges $4 for bracelets and $5 for earrings.
Her cost to make x bracelets and y earrings is $60.
The equation 4x + 5y = 60 represents this situation.
The graph of this equation is a line. What is the
slope of the line?

5/ 1/3=15 i think sorry if im wrong

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
