Step-by-step explanation:
x*0.75=36
x=36/0.75=48 $
Answer:
1. 15
2. 8
Step-by-step explanation:
The two sequence are geometric progression GP, because they follow a constant multiple (common ratio)
The nth term of a GP is;
Tn = ar^(n-1)
Where;
a = first term
r = common ratio
For the first sequence;
The common ratio r is
r = T3/T2 = 540/90 = 6
r = 6
T2 = ar^(2-1) = ar
T2 = 90 = ar
Substituting the values of r;
90 = a × 6
a = 90/6
a = 15
First term = 15
2. The sam method applies here.
Common ratio r = T3/T2 = 128/32 = 4
r = 4
T2 = ar^(2-1) = ar
T2 = 32 = ar
Substituting the values of r;
32 = a × 4
a = 32/4
a = 8
First term = 8
An input is were you put a number to get the answer. a output is were you take away the answer to get the correct
The answer is z = -13.9
In order to solve this, you need to use inverse operations. The inverse operation of addition is subtraction. So, this is the function we'll use
4.9 + z = -9 ----> subtract 4.9 from both sides
z = -13.9
