Answer:
30x + 15y
answer is d
Step-by-step explanation:
4.
x=2y
y=x-2
(Substitute)
x=2(x-2)
x=2x-4
-x=-4
x=4
Plug x=4 into both equations to find y and check
4=2y
2=y
y=4-2
y=2
(4,2)—> Blank 1:4 and Blank 2:2
5.
x=2y-3
x=2y+4
2y-3=2y+4
No solution —> Blank 1: NS and Blank 2: NS
Answer:
the answer is $222.86
Step-by-step explanation:
you would take the 234.15 and subtract the 56.29 dollars and then you would add the 45 dollars to the account to equal 222.86 us dollars
If the rate at which the temperature fell is 4/5 degree/hour then we can simply multiply 5 hours to get our answer.
4/5 * 5/1 = 20/5 = 4
So, it would change a total of 4 degrees.
