Answer:
w=5h-8
Step-by-step explanation:
Take the original formula h=(1/5)w+(8/5)
Subtract -8/5 on both sides to isolate the w, so h-8/5=(1/5)w
Now you have to get rid of the 1/5, so multiply 5(h-8/5), the 5 in the 8/5 cross each other out. You are left with 5h-8
Answer:
4374
Step-by-step explanation:
common ratio is -3
geometric sequence
an = a1 * r^(n-1)
a8 = -2*-3^(8-1)
a8 = -2*-3^7
a8 = -2 * (-2187)
a8 = 4374
