10 - 2x = 120
120 + 10 = 130
130 / 2 = 65
x = 65
2(65) - 10 = 120
Answer:It should be x=1 not sure thought.
Step-by-step explanation:
1.25 hours for each lawn. 1.25 x 7 = 8.75.
162.15 is the answer because you have to multiply 0.15•141 then add 21.15 to the 141 :)
According to PEMDAS, you would look in the parenthesis first. In the first set of parenthesis we have an exponent. 10x10x10x10 is 10,000. Then we multiply this by 2.5. We now have 25,000. We put this to the side..
Next, we do the same thing on the other side -- 10x10x10 is 1,000 and then you multiply that answer by 1.5 and we have 1,500. Now we can subtract. 25,000 - 1500 = 23,500 :)
