Answer: hope it helps
Step-by-step explanation:
2x+11 absolute value equals 2x+11, then 2x+11=7, subtract 11 from itself, and 7 you get 2x=4 divide both sides by 2 an you get -2=x.
Answer:
$30
Step-by-step explanation:
We know that the cost of all of the books was 228 - 18 = 210 dollars because Mike had 18 dollars left over. Assuming that each book cost the same amount, we know that each book costs 210 / 7 = $30.
Answer:
subtract 27 from 85
Step-by-step explanation:
85
-27
———
58
7 cannot be subtracted from 5 so borrow a 10 to make it 7 subtracted from 15 and then the 8 tens becomes 7 tens so 7-2=5
58+27=85 to check your work
Answer:
The correct answer is n = -9.
Step-by-step explanation:
-13n + 20 = -11n + 38
20 = -11n + 38 + 13n Add 13n to both sides
20 = 2n + 38 Combine like terms
20 - 38 = 2n Subtract 38 from both sides
-18 = 2n Simplify
-9 = n Divide both sides by 2
OR
-13n + 20 = -11n + 38
-13n = -11n + 38 - 20 Subtract 20 from both sides
-13n = -11n + 18 Combine like terms
-13n + 11n = 18 Add 11n from both sides
-2n = 18 Simplify
n = -9 Divide both sides by -2
