Answer:
7.5 should be the answer sorry if its wrong i don't have all of the information
5x + y = 15
y = -5x + 15
Substituting y= -5x+15 from first equation into second equation:
3x + 2y = 16
3x + 2·(-5x + 15) = 16
3x - 10x + 30 = 16
-7x + 30 = 16
7x = 30 - 16 = 14
x = 2
Substituting x=2 into the first equation:
5x + y = 15
5(2) + y = 15
10 + y = 15
y = 15 - 10
y = 5
So your final answers are x=2 and y=5.
Answer:
9, 10
Step-by-step explanation:
square root of √93 is 9.64.
Thus, we see that the number 9.64 is greater than but less than 10.
On number line it can be represented as
-∞ _____________7___8___9__9.64___10___11_______+∞
Thus, we see that the two whole numbers between which √93 lies is 9, 10
