The answer would be 17 just divided 85 by 5 and you'll get your total :)
X + y = 12 . . . . . . . . (1)
x - 3y = -30 . . . . . . . (2)
(1) - (2): 4y = 42
y = 10.5
Answer:
b. 2 feet
Step-by-step explanation:
The formula for volume of a cylinder is: V=πr^2h
Start by plugging in what they give you
V=πr^2h
314 =π(r)^2(25)
314 = 25π(r)^2
divide both sides by 25π, which is 78.5
4 = r^2
take the square root of both sides
r = 2
Answer:
3
Step-by-step explanation:
If you substitute the values x = 0 and y = −5 into the second equation, you get a false statement: 2(−5) − 10 = 2(0). To solve this system, try rewriting the first equation as x = 2y − 8. Then substitute 2y − 8 in for x in the second equation, and solve for y. The correct answer is x = −2, y = 3.
Not what I really think it might be, but I hope it helped you!
