Answer:
what are the answer choices?
Explanation:
Equation: x + 1 = 9
Solving Steps:
x + 1 = 9 (<em>subtract both sides by 1)</em>
x + 1 - 1 = 9 - 1 (<em>simplify the following)</em>
x = 8
Then check for solution:
x + 1 = 9
[insert x = 8]
8 + 1 = 9
9 = 9
As both sides are equal, the statement is true.
Answer:
500km
Step-by-step explanation:
Let the journey covered in kilometers be A
Since
1 km = 1 mile
x km = 500 miles
Cross multiply
X km x 1 = 500 miles x 1 km
X = 500km
The journey covered in kilometers will be 500km
Answer:
5 hours
Step-by-step explanation:
Lillian is deciding between two parking garages.
Let the time required to park be represented by t
A = Amount
From Garage A
A = the amount Garage A would charge if Lillian parks for t hours
B = the amount Garage B would charge if Lillian parks for t hours.
Garage A
Garage A charges an initial fee of $4 to park plus $3 per hour.
A = $4 + $3 × t
A = 4 + 3t
Garage B charges an initial fee of $9 to park plus $2 per hour.
B = $9 + $2 × t
B = 9 + 2t
The hours parked, t, that would make the cost of each garage the same is calculated by equating A to B
A = B
4 + 3t = 9 + 2t
Collect like terms
3t - 2t = 9 - 4
t = 5 hours
Therefore, the hours parked, t, that would make the cost of each garage the same is 5 hours
