You're going to want to combine like terms first off, so 2x+3x=5x. Then you have 5x+7=-41. Now you subtract 7 from both sides, and basically undo that function so you have 5x=-48. Then you do the opposite of multiplying 5, so you divide five from both sides and get -9.6. So x=-9.6. Is that what you wanted? Because if not, ignore this.
Answer:
120 seconds
Step-by-step explanation:
To solve this question you have to make equation of both gallon.
Gallon 1 have 130 gallons of water at the start and filled by 1/4 gallon each second. If x equal to the time in seconds, the equation of gallon 1 volume will be:
g1= 130+ 1/4x
Gallon 1 have 200 gallons of water at the start and drained by 1/ 3 gallon each second, the equation of gallon 2 volume :
g2= 200- 1/3x
When gallon 1 volume equal to gallon 2, it mean g1=g2
g1= g2
130+ 1/4x = 200- 1/3x
130- 200= -1/3x -1/4x
-70= - 4/12x - 3/12x
-7/12x= -70
7/12x= 70
x= 70*12/7
x= 120
Answer:
x = -5q
Step-by-step explanation:
-x/5 = q
-x = 5q
x = -5q
The y intercept is 3 because the line intercepts the y axis at 3.
