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%.

Please help!!!!!<br>Solve the equation 5(2y - 1) - 2(3y)= 1<br>​
-Dominant- [34]

Answer:

y = 3/2

Step-by-step explanation:

5(2y - 1) - 2(3y) = 1

First we use distributive property:

10y - 5 - 6y = 1

because 5 × 2y = 10y

and -2 × 3y = -6y

Now we combine the like terms:

4y -5 = 1

because 10y - 6y = 4y

Now we have to send the -5 to the other side. (when we send it to the other side it becomes positive because right now it is negative)

4y = 1 + 5

Again we combine the like terms:

4y = 6

(because 5 + 1 = 6)

Now we have to send the 4 to the other side because we need to get the y value. (when we send it to the other sidr it will be divided)

y = 6/4

and we simplify:

y = 3/2

And we cannot simplify or do anything else. So that is the answer.

Hope that helped!
