Answer: you bought 9 burgers and 16 tacos
Step-by-step explanation:
Let x represent the number of burgers that you bought.
Let y represent the number of tacos that you bought.
You buy a total of 25 burgers and tacos. It means that
x + y = 25
The burgers cost $3.50 each and the tacos cost $2.25 each. The total cost of the burgers and tacos that you bought is $67.50. It means that
3.5x + 2.25y = 67.5- - - - - - - - - - - - 1
Substituting x = 25 - y into 1, it becomes
3.5(25 - y) + 2.25y = 67.5
87.5 - 3.5y + 2.25y = 67.5
- 3.5y + 2.25y = 67.5 - 87.5
- 1.25y = - 20
y = - 20/ - 1.25
y = 16
x = 25 - y = 25 - 16
x = 9
2/3 / 4 = 2/3 / 4/1 During division, the 2nd fraction flips over and the sighn becomes its opposite. division to multiplication.
2/3 * 1/4 =2/12 or 1/6.
Answer:
60
Step-by-step explanation:
3/2t-16=4/3t-6
+16 +16
3/2t=4/3t+10
-4/3t
(t/6)6/1= 10(6/1)
t=60
