Answer:
B) x = 2, y = 1
Step-by-step explanation:
Add the two equations to eliminate the x-variable.
(x +3y) +(-x +6y) = (5) +(4)
9y = 9 . . . . . . .simplify
y = 1 . . . . . . . . divide by 9
You can substitute this value into either equation to find x.
x + 3(1) = 5
x = 2 . . . . . . . . subtract 3
The solution is (x, y) = (2, 1).
Answer: C. 2.889 .
Step-by-step explanation:
To find : A decimal expression equivalent to 
.
When we divide 26 by 9 , we get 2.88888888889 which is approximately equal to 2.889 [Round off to the nearest thousandth place]
Hence, the decimal is equivalent to is 2.889.
Hence, the correct option is C. 2.889 .
Answer:
V = 4/3 (3.14) r^3
V = 4/3 (3.14) (5^3 - (4)^3)
V = 4/3 (3.14) (125 - 64)
V = 255.4 cm cubed
Step-by-step explanation:
Answer: x < -3.5
Step-by-step explanation:
Subtract 3 from both sides and we get
-4x > 14
We divide -4 on both sides, but be careful because we have to flip the sign since it's a negative number.
x < -3.5
