Answer:
3a -2
Step-by-step explanation:
2-(-3a+4)
Distribute the minus sign to each term inside the parentheses
2 - -3a -4
2 + 3a -4
Combine like terms
2-4 +3a
-2 +3a
We usually put the variables first
3a -2
The answer is D, -3.
3 and -3 cancel each other out when added.
Answer:
15 %
Step-by-step explanation:
42 = members of team A
60 = members of team B
Let x = percent of members transferred
0.01x × 60 = 0.6x = no of members transferred
60 - 0.6x = 42 + 0.6x
60 = 42 + 1.2x
18 = 1.2x
x = 15
15 % of the members on Team B must be transferred to Team A.
Check:
60 - 0.6 × 15 = 42 + 0.6 × 15
60 - 9 = 42 + 9
51 = 51
OK.
