Yes it will. For every one hour, the train travels 170 miles. That’s the rate of change/ the ratio-> 1:170
I'm guessing it 30 it says 3 times the nber of trumpet players
Answer:
swap the middle two steps to put them in order
Step-by-step explanation:
The steps in order would be ...
- -11 -5z = 30z +24 . . . . . eliminate parentheses
- -11 = 35z +24 . . . . . . . . add 5z
- -35 = 35z . . . . . . . . . . . . subtract 24
- -1 = z . . . . . . . . . . . . . . . . divide by 2
Your question does not make sense unless you can estimate but the answer would be 20.625
Work:
You have to multiply 5.50 to 3.75 because 45 is 75 percent of 60
You want to solve for 'z'.
First combine like terms on either side of the equal sign.
Left side: 9z +2 ----> No like terms, leave alone
Right side: 6z - 10 -z - 4 ----> circle like terms and add
6z -z = 5z
-10 -4 = -14
Now the equation is:
9z + 2 = 5z - 14
Get all the 'z' terms on the left side and all the numbers on right side.
You can move a term to the other side if you flip the sign.
Move 5z to left side, flip the sign to -5z
Move '2' to right side, flip the sign to -2
9z - 5z = -2 -14
Add like terms
4z = -16
Divide by 4 on both sides
z = -4
