In afternoon it was -2 degree cold. At night it went 5 time colder. How cold was it at night?
Step-by-step explanation:
Answer:
x=9
y=16
z=12
Step-by-step explanation:
X - tickets
----------------------------------
167x + 19x + 16 = 1132
186x + 16 = 1132
186x = 1132 - 16
186x = 1116
x = 1116 : 186
x = 6 tickets (answer).
So standard form is Ax+By=C
Since the problem is already in that form you don’t need to switch it around however A has to be more than 0 (so positive). Divide the equation by -3 to get the answer x-4y=-8
2. $16.90 + $5.99 = $22.89
22.89-5= $17.89 The answer is reasonable
3. 14.85 x 3= $44.55 this is the total cost
to find the tax, multiply 44.55 times 0.2
The answer is not reasonable, the tip should be $8.91
