Answer:
one months bill would be $32+$0.75X=$47 X= minutes use over given time.
X= 20
Step-by-step explanation:
13 should be b and
14 is a because geometric mean to have a common ratio
(3/5 + -1/4)/(7/10)
get a common denominator of 20
3/5 * 4/4 =12/20
-1/4 * 5/5 = -5/20
7/10 *2/2 = 17/20
replace
(12/20 - 5/20)/(14/20)
add the top
(7/20)/(14/20)
copy dot flip
7/20 * 20/14
7/14
1/2
99(x-77)=99(x+88)
99x-7623=99x+8712
99x-99x=8712+7623
0=670824.no solution as x becomes 0
Answer:
The answer is A
Step-by-step explanation:
2t(t-4)
(2t x t)(2t x -4)
2t^2 - 8t
