Answer:
-3 4/9
Step-by-step explanation:
The fractions all have the same denominator, so are easily added.
Of course, you know how to add signed integers.
4/9 - 3/9 - 5/9 + 5 - 8
= (4 -3 -5)/9 +(5 -8)
= -4/9 -3
= -(3 4/9)
Let x be for unknown number. Let x be first number .
X+1 To be second number .x+2be third number. X+(x+1)+(x+2)=312.
Simplify to get 3x+3=312 . Subtract 3 from both sides 3x-3=312-3. Once you subtract get 3x=109.then divide 3 both sides . 3x/3=309/3. To get x= 103.
Now once you have that First number 103. Second number 103+1=104 . And third number 103+2=105. To check add them 103+104+105=312
For when x is 4 g will be 80 and f will be 108 for when x is 5, g will be 160 and x will be 110 so option 1 as 160-110 is 50
Hope it helped
Answer:
