73/260 73 is what percent of 260. also 42/220 42 is what percent of 220. please help.
BlackZzzverrR [31]
73 = x(260).  Translate the word "is" as equals, and "of" as multiply.  Divide both sides by 260 (as you already did):  73/260 = x

73/260 = 28%.  (Move the decimal point two positions to the left).

42/220 = 19%.

Y-1=2/3(x+9) in standard form
UNO [17]
First, distribute 2/3 to the values in the parentheses. This gives you y-1=2/3x+6.

To get y alone, we add 1 to both sides. This gets you y=2/3x+7.

y=mx+b
y=2/3x+7

It matches the standard form, so your final answer would be y=2/3x+7.
