Answer:
7.5 feet
Step-by-step explanation:
4/5=6/x
cross multiply
4x=30
x=7.5
Answer:

it seems like the first term is -64, so lets write the formula accordingly:
a_n = a1(r)^(n-1)
where 'n' is the number of terms
a1 is the first term of the sequence
'r' is the ratio
the ratio is
because -64 *
= 16 and so on...
the explicit formula is :
= 
To rearrange you must first simplify
aq-ac=d
add ac to each side:
aq=d+ac
then divide by a:
q=(d/a)+c and this is your answer
5x-9 = 3x+3
2x-9 = 3
2x = 12
x= 6
