Answer:
200
Step-by-step explanation:
half of 200 is 100.
x / 2 = 100
200 / 2 = 100
2x + 3y = 6
Put this into y=mx+b form (which is also called slope-intercept form)
Where m=slope and b=y-intercept
In order to put this into slope-intercept form, we simply need to subtract 2x from both side.s
3y = 6 - 2x
Then, divide both sides by 3 so that we fully isolate y.
3y ÷ 3 = (6 - 2x) ÷ 3
Simplify.
y = 2 - 2/3x
Put this into order by moving "x" onto the correct place.
y = -2/3x + 2
Therefore -2/3 is the slope, as it is in the "m" spot.
Hope I helped! :)
First car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20
Final answers:
First car=20 gallons
Second car=35 gallons
There are no solutions. The slopes of both lines are the same so they are parallel: they will never intersect. Therefore, there cannot be a solution.
1,093,313 would come to 1,090,000
