or 4 and 5
Equilateral correctly describes pentagon
A) Tonya bought 3 games at X price, so 3X would be total amount.
B) Tony's cost was 0.50 less than X, so x-0.50, he bought 4 games, so he spent 4(x-0.50).
C) Set those to equal to solve for x:
3x = 4(x-0.50)
D) Solve:
3x = 4(x-0.50)
Distribute:
3x = 4x - 2
Subtract 4x from both sides:
-X = -2
Multiply both sides by -1:
X = 2
E) Since X is the amount Tonya paid per game, Tony paid X - 0.50, so Tony paid 2 - 0.50 = $1.50 per game.
Check:
Tonya: 3x = 3(2) = $6 total
Tony: 4(x-0.50) = 4(2.00 - 0.50) = 4(1.50) = $6 total
Answer:
128
Step-by-step explanation:
Set this up as a proportion with miles on the top and km on the bottom:
If we want to know how many km are in 80 miles, we put the variable with the km stuff on the bottom and 80 on top and cross multiply to solve for the variable:
so
5x = 640 and
x = 128
That means that 80 miles is equivalent to 128 km
The answer will be 8.555555555555555556 (it's a repeating decimal)
