Answer:
Emmanuel purchased 11 pounds of soil last week.
Step-by-step explanation:
If we want to find the number of pounds of soil Emmanuel purchased last week, we will have to work backwards.
We know that the amount is 5 lb more than twice the amount of potting soil he bought last week. This info gives us an equation.
2x + 5 = 27, as its twice the amount last week and 5 lbs more. Now we solve.
2x + 5 = 27 | Subtract 5 from both sides
2x = 22 | Divide both sides by 2
x = 11

Step-by-step explanation:
( x + 2 ) + ( x + 2 ) + x + x = 48
4x + 4 = 48
- 4 - 4
4x = 44
divide by 4
x = 11
You can use mental math to perform the following addition by knowing that certain numbers equal a certain number. for instance, you know that 9+2 is equal to 11. you don't need a calculator to solve that. then you know that 1+8 is equal to 9.since you are adding 11 you know that the answer is 19. you can use that to answer to following equation.
