6x - y = -8
y = 6x + 8 - not plug this in the first equation
4x - y = -3
4x - (6x + 8) = -3
4x - 6x - 8 = -3
-2x = -3+8
-2x = 5
x = 5/(-2)
x = -5/2
Now we can solve for y.
As we said before, y = 6x + 8
y = 6* (-5/2) + 8
y = -15 + 8
y = -7
<span><span>{x,y} = {-5/2,-7}</span> is the solution to the system</span>
Answer:
second, third,first
Step-by-step explanation:
first
3/2=1.5
9^1.5=27
second
1/3=0.333
27^0.333=3
third
2/3=0.667
125^0.667=25
Suppose the first one is n, the second is then n+1, the third is n+2, ....
n+(n+1)+(n+2)+(n+3)+(n+4)=265
5n+10=265
5n=255
n=51
so the 5 consecutive integers are: 51,52,53,54,55
53.69*.15= 8.05
Change the 15% to a decimal before multiplying. Round answer to two decimal places since it is money (unless told otherwise)
