Step-by-step explanation:
Answer:the price for one shirt is $20
the price for one pair of pants is $12
Step-by-step explanation:
The question is incomplete. The complete question is
A shopper purchased 8 t shirts and 5 pairs of pants for $220. The next day he purchased 5 t shirts and 1 pair of pants for $112. How much does a t shirt and each pair of pants cost.
The solution is
Let x represent the price for one t shirt.
Let y represent the price for one pair of pants.
A shopper purchased 8 t shirts and 5 pairs of pants for $220. This means that
8x + 5y = 220 - - - - - - - - - -1
The next day he purchased 5 t shirts and 1 pair of pants for $112. This means that
5x + y = 112 - - - - - - - - - - - 2
Multiplying equation 1 by 5 and equation 2 by 8, it becomes
40x + 25y = 1100
40x + 8y = 896
Subtracting, it becomes
17y = 204
y = 204/ 17 = 12
Substituting y = 12 into equation 2, it becomes
5x + 12 = 112
5x = 112 - 12 = 100
x = 100/5 = 20
in a right-triangle, like in the 1st Quadrant, cosine and sine are complements, so then
sin(x) = cos(90° - x)
cos(x) = sin(90° - x)
for this case, sin(<u>90°</u>) = cos(90° - <u>90°</u>), or just cos(0°) = 1.
Answer:
9 days
Step-by-step explanation:
1 day: 5/6 2 days: 10/6 3 days: 15/6 4 days: 20/6 5 days: 25/6
6 days: 30/6 7 days: 35/6 8 days: 40/6 9 days: 45/6
If you divide 45 and 6 by 3 you get 15/2. If you put 15/2 into a mixed number you would get 7 1/2. So 9 days would be your answer.
