Answer:
Ben has 225 seashells
Step-by-step explanation:
<u>Step 1: Use the ratio to see how many times the amount Andy has</u>
4 * n = 100
4n / 4 = 100 / 4
<em>n = 25 times the amount of the ratio</em>
<em />
<u>Step 2: Find out how many shells Ben has</u>
Use the 25 times the ratio to help
9 * 25
225
Answer: Ben has 225 seashells
<u>Check: See if the ratio still works</u>
Andy = 100
Ben = 225
100 : 225
(100/25) : (225/25)
4 : 9 -> Correct, so the answer is good
Answer:
To solve, we need to isolate the variable
The first step is to subtract 18 from both sides to "reverse" the addition
-6x+18=-6
-6x=-24
The second step is to divide -6 on both sides to "reverse" the multiplication
-6x=-24
x=4
Hope this helps! :)
Answer:
10 √3What is the Square Root of 300 in Simplest Radical Form? We need to express 300 as the product of its prime factors i.e. 300 = 2 × 2 × 3 × 5 × 5. Therefore, √300 = √2 × 2 × 3 × 5 × 5 = 10 √3. Thus, the square root of 300 in the lowest radical form is 10 √3.
Step-by-step explanation:
sorry if this is wrong :(
I tried my best <3
1 5/6 because you have to first find half of 3 which is 1 1/2 then you have to find half of 2/3 which is 1/3 then you have to find a common denominator then add. After that simplest form.
Given:
Required:
We need to find the solution by Vièta's theorem.
Explanation:
Compare 1st equation with
we get
Vièta's theorem is
now solve this equation and we get
because addition of 1 and 2 is 3 and multiplication is 2
Now for 2nd equation
apply Vièta's theorem
by this
because addition of 3 and -5 is -2 and multiplication is -15
