Answer:
z = 4/5
Step-by-step explanation:
3(5z + 7) = 33
Divide each side by 3
3/3(5z + 7) = 33/3
5z+7 = 11
Subtract 7 from each side
5z+7-7 = 11-7
5z = 4
Divide by 5
5z/5 = 4/5
z = 4/5
The sequence is to multiply by -3. Therefore, you want to multiply by -3 which gives you 108. Since it is a negative by a positive the answer would be negative. The next term would be -108.
W = 2. Don’t listen to the other guy!
.45 * 120 = 54
.072 * 54 = 3.888
54 + 3.888 = 57.888= $57.89
Answer:
You don't have enough money for 2 downloads
Step-by-step explanation:
The cost of downloading one movie is ...
g(1) = 2·1 = 2 . . . dollars
The cost of downloading one song is ...
f(1) = (1/2)(1) +2 = 2.50 . . . dollars
Downloading 2 songs, 2 movies, or one of each will cost more than $2.50.
You don't have enough money for 2 downloads.
