Solve for w: w^2-4 w+11 = 0
Subtract 11 from both sides: w^2-4 w = -11
Add 4 to both sides: w^2-4 w+4 = -7
Write the left hand side as a square: (w-2)^2 = -7
Take the square root of both sides: w-2 = i sqrt(7) or w-2 = -i sqrt(7)
Add 2 to both sides: w = 2+i sqrt(7) or w-2 = -i sqrt(7)
Add 2 to both sides: Answer: |w = 2+i sqrt(7) or w = 2-i sqrt(7)
Independent variable =$27 rental fee.
Dependent variable =$0.45 per mile - because it depends on how many miles were driven.
1)
0.25q + 0.10q =105
0.35q = 105
q =105 / 0.35
q=3 quartes x 0.25 =0.75 cents
3 x 2 =6 nickels x 0.05 =0.30 cents
0.75 + 0.30 =105=$1.05
2)123 / 3 =41 the average of the 3 numbers. Therefore:
40 + 41 + 42 = 123
(2^9) / (2^3) =2^n, solve for n
2^(9-3) =2^6, therefore,
n = 6
A newborn baby has about 2.6x10^10 cells. An adult has about 4.94x10^13 cells. How many times as many cells does an adult have than a newborn? Write your answer in scientific notation.
[4.94 x 10^13] / [2.6 x 10^10] =1,900 = 1.9 x 10^3 - times more cells than a baby.
Scientific notation has no problems!!. It is simply a shorthand for writing very large or very small numbers, such as:123,456,789,203,476,397=1.23 x 10^17.This number is written in scientific notation.
I think it is:[47 + 9]/18
Using PEMDAS
47+0.5= 47.5
Or it might be 56/18 = 3.111111111111
The number is 9.
9 / (3/4)^2 = 16
NIce to meet you hamiltrash.
x = Multiple things.
x = 3
x = 2
x = 1
x = 0
x = -1
x = -2
x = -3
It goes on for a long time.
He would've saved $5. 50*10%=5.
So he would have spent $45.
I will give 3:
2:5
6:15
40:100
Factors of 16 are 1, 2, 4, 8, and 16. Factors of 28 are 1, 2, 4, 7, 14, and 28. Factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
The GCF of 16, 28, and 48 is: 4.
I have 2.

-2+4 is like 4-2, just switch the numbers around: +4-2 (Positive Four minus Negative Two)
Yeaaa. I'm so smartz.
Thanks!
28 /20 = [7 * 4] / [ 5 * 4] = 7/5 = 1 + 2/5 .....just as MathPeacock found !!!!
(1 2/5)
No prob....
Español? Just kidding
Thanks
i think it is
