Answer:
You need to do 5 times 3 for 15 a d then add 9 to get 24, so 47 is not less than or equal to 5 times 3 add 9
Step-by-step explanation:
Answer:
195
Step-by-step explanation:
3 x 60 = 180
180 + 15
195
P = paddling speed
C = speed of the current
Upstream: 6 = 4 (P - C. Downstream: 6 = 3 (P + C)
4P - 4C = 6
3P + 3C = 6
12P - 12C = 18
12P + 12C = 24
Add the equations:
24P = 42. P = 42/24 = 1.75 mph
Subtract the equations:
-24C = -6
C = 0.25 mph
Assuming O=o
group then add like terms
1o+2a+1b-2o-1b+1o=
1o+1o-2o+2a+1b-1b=
0+2a+0=
2a
