Answer:
-11/10 or -1.1
Step-by-step explanation:
To start, let's get rid of those pesky decimals by multiplying everything by 2. Then we get 9 + 20r = -13. Now, let's isolate the r by subtracting 9 from both sides to get 20r = -22. Finally, we need to divide everything by 20 to get r = -11/10 or -1.1.
12 gallons because u have to find 20÷5 to get 4 and 5÷5 to get 1 and then u have to find what 48÷4 is and it is 12 and u have to do 1×12 to get 12 and that is your answer
The surface are of the shape is 251.5 units (sorry if that is wrong)
Writing this word problem symbolically: 6x + 4 = x = 11.
Combining like terms, 5x = 7, and so x = 7/5 (answer)
