Answer:
5
Step-by-step explanation:
Given: 5^3– 10^2 = X(8 – 2) + 2X – 3X
Solving the equation to find the value of x.
⇒
Using the distributive property of multiplication, multiplying x with 8 and -2
⇒
cancelling out -2x and 2x
⇒
⇒
Multiplying both side by 5
⇒ x=
∴ x= 5
Hence, the value of unknown is 5.
Answer:
The given equation will have value less than 100 whenever the value of b is greater than 12.89
Step-by-step explanation:
For the given equation, p(b) = 520 × to have a value less than 100 we can establish inequality as:
p(b) < 100
or, 520 × < 100
or, ×
<
or, <
or, ㏒ ( ) < ㏒ (
)
or, b× ㏒ 0.88 < ㏒ ()
or, < b
or, 12.89 < b
Hence for the equation to have value less than 100, b must be greater than 12.89.
