Suggesting that you want this in standard form, in terms of quadratic equations, you would technically follow a process similar if not almost exactly like the 2 - step equation method with the exception of separating the (x)s and the equations to find x and then plug it in and what-not.
With that being said you would subtract 5 in (x+5) from said 5 in the second equation and -10 in the first equation in order to get 2x^2+7x-15, you would continue to do the same for the x by subtracting it from both ends making the 7x a 6x because there is a 1 at the beginning of each x if there is no number that is shown already. Which finally gives you the equation (y= 2x^2+6x-15)
Answer:
$36,000
Step-by-step explanation:
5400=15%
x=100%
Now, we cross multiply. 540000/15=36000
Answer: I believe it's 60
Step-by-step explanation: considering that there's (2x) its the only one that'll make since since the straight line which is half the circle is 180.
60+60(2)
60+120
180
Answer:
Step-by-step explanation:
1 liter =1000milliliters
x liter = 1478 millileter
cross multiplication
x *1000 = 1478*1
x=1478/1000 = 1.478 liters
