Given expression is
-33/-10- (-45.3+ 35.2)
Problem says that it is simplified.
After simplification it gives:
-33/-10+?
Now we need to find the unknown value that goes in place of ?.
Notice that it is expression having only constants so we will get a unique answer not the smallest or largest value.
Now let's find the value of unknown that goes in place of ?
-33/-10- (-45.3+ 35.2)= -33/-10+?
we see that -33/-10 is on both sides so we can remove that
- (-45.3+ 35.2)= ?
Now let's simplify the left side by distributing the negative sign
+45.3 - 35.2= ?
10.1 = ?
Hence the unknown value is 10.1 that goes in place of ?.
Answer:
2 1/4 gallons or 2.25 gallons
Step-by-step explanation:
3/4 is 1/3 of the wall
then 9/4 is all of the wall
so 9/4 simplified is
2 and 1/4 gallons
So the price would first be 12*1.5 which is 18, then multiply by 1.07 to get 19.26
