Answer:
99
Step-by-step explanation:
x = 90 x 10/100 + 90
=> x = 900/100 + 90
=> x = 9 + 90
=> x = 99
Answer:
Step-by-step explanation:
In order for 4*t to equal d, the 4 has to represent a rate with respect to time because the multiplication between them will cancel the time unit. We know this because of the formula d = rt with 'r' being rate
a: 4 is the rate at which Shelby walks, 4 miles per hour
b: T is replaced with 32, so the expression tells us the distance Shelby travels in 32 hours at a rate of 4 miles per hour
3/4=2/4=5/4
5 divided by 4 or 5/4= 1 1/4
6 1/4+5=6 1/4
hope that helps. It wasn't very clear. so those are the questions I got out of that and those are the answers. Again hope this helps
What is the solution (not answer) to (not too) x^2 - 3x + 5 = 0?
This is a quadratic equation. Two possible approches to solving it are
1) quadratic formula, and
2) completing the square.
Let's use the quadratic formula:
a=1, b= -3, c = 5
Then
-(-3) plus or minus sqrt( [-3]^2 - 4(1)(5) )
x = --------------------------------------------------------
2
3 plus or minus sqrt(9-20) 3 plus or minus i*sqrt(11)
= ------------------------------------- = ------------------------------------
2
Please note: These are complex roots, due to the " i ".
4n^4 √3n I believe would be the simplified form.
