2a/3 + 1
Step-by-step explanation:
Combine multiplied terms into a single fraction-
2/3 a + 1
2a/3 + 1
They should divide 1642 by a cubic number to get the answer
Answer:
my answer is b) 0
Step-by-step explanation:
coz
-3+4+2+1+-4+-1+3+-2=0
divided by 8 is 0
Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h
Step-by-step explanation:
1.before starting first collect the like terms.
5(2x+1)=10x
the like terms are 10x and 2x
2. 5+1=10x-2x because the 2x us crosing the equality sign
that is
6=8
