Answer:
196608
Step-by-step explanation:
3, -12, 48, -192, ... is a geometric sequence with first term 3 and common ratio -4. Note that (-12)(-4) = 48, that (48)(-4) = -192, and so on. The general formula for a geom. seq. is a(n) = a(1)r^(n-1), where a(1) is the first term and r is the common ratio. In this particular case, we have
a(n) = 3*(-4)^(9-1) = 3*(-4)^8 = 3(65536) = 196608

Answer:
x=4
Step-by-step explanation:
1. 7x+56=14x+28 using distributive property (with the number of stes you need to have, this may count as 2)
2. 56=7x+28 by subtracting 7x from each side
3. 28=7x by subtracting 28 from both sides
4. x=4 by dividng by 7
5. plug back into equation
7(4)+56=14(4+2)
28+56=14(6)
84=84
Answer:
$299
Step-by-step explanation:
Given that 70% is $230 you can divide this by 7 to get 10%.
10% is 23. The remaining percentage we need is 30.
Soo 10% x 3 = 30%. (23x3)
23 x 3 = 69.
69 + 230 = $299
Answer:
there is no solution for these linear equations in two variables.
since a1 (y) = a2 (y)
b1 (5x) = b2 (5x)
but, c1 (12) not equal to c2 (18)
