6 1/3 -: 5/6

your options are:

A) 36/5
B) 95/18
C) 38/5
D) 12/5

2) 3-7^2 + 3 * 4^2

C) 304
D) 64

3) Find the following when a = -2, b = 3, c = -1/3
(7b - 2)/(-a) +1

A) -21/2

B) 17/2

C) 4/2

D) 21/2

4) Find the following when a = -1, b = 5, c = -2/3.
(7b-10)/a -1

a) 11
b) -26
C) -13
D) 28

5) Use the formulas for a cylinder:
r = 5
h = 7
V = ?


a) 12pi

b) 175pi

c) 24pi

d) 18pi

Answer 1

(6 1/3) / (5/6) = (19/3) / (5/6) = 19/3 * 6/5 = 114/15 = 38/5

3 - 7^2 + 3 * 4^2
3 - 49 + 3 * 16
3 - 49 + 48
- 46 + 48
2

(7b - 2) / (-a + 1)....a = -2, b = 3, c = -1/3
where is he c in this equation ? Because if I just use a and b, my answer is not an answer choice

(7b - 10) / (a - 1)...a = -1, b = 5, c = -2/3
same as before...where is the c in this equation

V = (pi) r^2* h
V = (pi)(5^2)(7)
V = (pi)(25)(7)
V = 175(pi)
