6x-28 is what I got for this
Answer:
- plane: 530 mi/h
- wind: 40 mi/h
Step-by-step explanation:
Let p and w represent the speeds of the plane and the wind. The relation between time, speed, and distance is ...
speed = distance/time
p +w = (2565 mi)/(4.5 h) = 570 mi/h
p -w = (2205 mi)/(4.5 h) = 490 mi/h
Adding these speeds, we get ...
(p +w) +(p -w) = (570) +(490) mi/h
2p = 1060 mi/h
p = 530 mi/h
Then the speed of the wind is ...
w = 570 mi/h -p = (570 -530) mi/h = 40 mi/h
The plane's speed is 530 mi/h; the wind speed is 40 mi/h.
Answer:
3 dress shirts and 3 T-shirts
4 dress shirts and 1 T-shirt
Step-by-step explanation:
You must spend at least $93 and no more than $100.
2 dress shirts: $42 + 5 T-shirts: $60 = $102 too much money
2 dress shirts: $42 + 4 T-shirts: $48 = $90 too much money left
3 dress shirts: $63 + 3 T-shirts: $36 = $99 this works
4 dress shirts: $84 + 1 T-shirt: $12 = $96 this works
5 dress shirts: $105 too much money
Answer:
3 dress shirts and 3 T-shirts
4 dress shirts and 1 T-shirt
