Given:
4:x::x:16
To find:
The value of x.
Solution:
We have,
4:x::x:16
It means, we have
4:x = x:16
It can be rewritten as
On cross multiplication, we get
Taking square root on both sides.
Since ratio can be negative or positive, therefore, the value of x is either -8 or 8.
Ok so 3x5 is 15 then 15 x 2 is 30 your answer is 30
hope this helped
Answer:
168
Step-by-step explanation:
you get 3.5% of 800 and then multiply it by 6.
Lenny's net proceeds algebraically are found as;
<h3>What is the equation?</h3>
A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.
Let the bought share will be $ x, and $y is the price per share
Paid fees to the broker = $ 20
The total amount spent = $(xy+20)
The price at which each share sells = $ A
Broker commission = 2 %
The total amount obtained after selling the shares;
⇒ ax - 2% of ax
⇒ 98 % of ax
Hence, Lenny's net proceeds algebraically are found as;

Darin drives (B) 2m - 20 miles.
<h3>
What is the distance?</h3>
- Distance is a numerical measurement of the distance between two objects or points.
- The distance can refer to a physical length or an estimate based on other criteria in physics or everyday usage.
- The distance between two points A and B are sometimes denoted as |AB|.
To find how much Darin drives:
Given:
- The number of miles driven by Sam = m.
- As Kara drove twice as many miles as Sam,
- The number of miles driven by Kara = 2m.
- As Darin drove 20 fewer miles than Kara,
- Hence, Number of miles driven by Darin = Number of miles driven by Kara − 20 = 2m − 20
Therefore, Darin drives (B) 2m - 20 miles.
