Answer: 3,75 ( 15/4)
Step-by-step explanation:
1/3 (6y - 9) = -2y + 13
6y/3 - 9/3 = - 2y + 13
2y - 2 = - 2y + 13
2y + 2y = 13 + 2
4y = 15
y = 15/4
y = 3,75
For the #2 it would be 3 because 50 goes into 138 2 times which will give you 100 with a remainder of 38. You can't leave behind the other 38 so you will bring another bus.
109.31
To find this you can convert 58% to decimal form, which is .58. Once you have a decimal form of a percent, you can multiply it by the number you are taking the percent of and get an answer. So .58 times something equals 63.4. You can write this as an equation:
.58x = 63.4
and solve for x, which would get 63.4/.58, which equals 109.31.
Its 272ft sq because if it is the area you can dig then you have to take away the No digging part and multiply the parts where you can dig.
