Answer:mr.Sinofsky used 2 tanks of gas altogether
Step-by-step explanation:
Mr.Sinofsky used 5/8 of a tank of gas on a trip to visit relatives for the weekend.
He used another 1 half of a tank commuting to work the next week. Converting 1 1/2 tank of gas to improper fraction, it becomes 3/2 tanks of gas.
He then took another weekend trip and use 1/4 tank of gas. Therefore, the total number of tanks of gas that Mr.Sinofsky used would be
5/8 + 3/2 + 1/4 = (5 + 12 + 2)/8 = 19/8
= 2 tanks of gas

Answer:
X^2-x- 8/x+4
Step-by-step explanation:
X+4 becomes a negative 4
Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.
X= 13
y=16
Work:
x+y=29
x=29-y
x+2y=45
29-y+2y=45
y=45-29
y=16
x=29-16
x=13
