X-4/3=10
Multiply 3 on both sides
x-4=30
Add 4 to both sides
Final Answer: x=34
Plan A = 50 + 0.05(x-500)
Plan b = 20 + 0.06 (x-200)
set A equal to B
50 + 0.05 (x-500) = 20 + 0.06(x-200)
50 + 0.05x - 25 = 20 + 0.06x -12
rearrange like terms on one side.
50 - 25 -20 +12 =0.06x -0.05x
17 = 0.01x
x = 1700 minutes.
Answer:
$666.25
Step-by-step explanation:
Use the equation A = P(1 + rt)
P=16.25
$650+$16.25=666.25
Answer:
c) 10
Step-by-step explanation:
You do 5 C 3 ( because you are choosing 3 from the remaining 5).
5C3 = 5!/(3!2!) = 10
2/3 = (z - 6) / 15
cross multiply
3(z - 6) = 2(15)
3z - 18 = 30
3z = 30 + 18
3z = 48
z = 48/3
z = 16 <===
