I'll get you started. Let x and y be the two numbers. we have: x + y = 74 (sum is 74) x = 4y - 6 (the number x is six less than 4 times y) Now that you have the equations use an algebraic techniques to eliminate one variable thereby solving for the other. If you need more help add a comment to your question.
Answer:
7+3x=Y
Step-by-step explanation:
Y= the total ammount she pays.
X= the number of games she wants to play.
$7 for the "shoes" and $3 for each game she wants to play
7+(3*4)= Y
7+12= $19
$73 = 3x + 7
-7 -7
$66 = 3x
66/3 = 3x/3
22 = x
x=22
Answer:
I believe the age of the triplets is 13
Step-by-step explanation:
Let y = total cost of the taxi service.
let x = amount of miles
We need to create a system of equations to solve this problem.
Taxi company 1: y = $0.25x + $5
Taxi company 2: y = $0.50x + $1
Set the equations equal to each other
$0.25x + $5 = $0.50x +$1.
Subtract $0.25x from both sides and subtract $1 from both sides.
$4 = $0.25x
Divide both sides by $0.25.
16 miles = x
The companies will charge the same amount of money at 16 miles
