You can change them into fractions with the same denominator: multiply 3/4 by 3 and 2/3 by 4
3/4 = 9/12
2/3 = 8/12
You could also convert them to decimals.
3/4 = 0.75
2/3 = 0.667
3/4 is greater than 2/3
Answer:
575
Step-by-step explanation:
.16x = 23 + .12x
Subtract .12x and then divide and get
.04x = 23
x = 575 minutes
$6.67 is 6.6666 rounded to the nearest cent.
The LCD of 1/2 and 5/6 is equal to the LCM of 2 and 6.
Multiples of 2 and 6
2: 2,4,6
6: 6,12,18
As you can see, the first number in both lines are 6.
To solve the two sets of equations simultaneously, subtract one equation from the other to obtain
3x^5 + 2x^2 - 10x + 4 - (4x^4 + 6x^3 - 11) = 0
3x^5 - 4x^4 - 6x^3 + 2x^2 - 10x - 7 = 0
This is a polynomial of degree 5 to be solved for zeros.
A graphing calculator will yield 3 real zeros (verifiable by Descartes Rule of Signs).
