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
Answer and explanation:
<h2>X</h2>
3x + 6y = 180 <em>Use the original expression to find x</em>
3x = 180 - 6y <em>Subtract 6y by both sides</em>
<em>Divide by 3 to get x</em>
x = 60 - 3y
<h2>Y</h2>
x = 60 - 3y <em>Use the new expression to find y</em>
x - 60 = - 3y <em>Subtract 60 by both sides</em>
<em>Divide by -3 to get y</em>
Answer:
Thomas is 19 years old
Step-by-step explanation:
Thomas's age is T
Huilan is 2 times Thomas's age or 2T
the sum of both ages is 57
That means T + 2T = 57
3T = 57
T = 57/3
T = 19
Since T is Thomas's age, Thomas is 19 years old
Huilan is 38 years old
