Answer:
of a second
Step-by-step explanation:
We can convert each time into fractions.
11.74 is the same thing as 
and 11.69 is the same thing as 
.
We know that 11 - 11 = 0, so we can focus on the fractions for now.
Let's subtract 
from 
.
.
We can now simplify 
by dividing both the numerator and denominator by 5.
.
Hope this helped!
To find the answer to this, you have multiply both expressions by each other. To do this, you have to multiply each term in the first expression by each term in the second expressions. This yields the following: 3x^4-9x^3-3x^2+5x^3-15x^2-5x+10x^2-30x-10. Combing like terms and simplifying gives the final expression: 3x^4 - 4x^3 - 8x^2 - 35x - 10
Answer:
The numbers are 5 and 20 respectively.
Step-by-step explanation:
Let two numbers are x and y.
According to question-
x + y = 25...............................(i)
Given x is smaller number and y is larger number.
then,
2 y - 3 x = 25..........................(ii)
To solve equation (i) and (ii)-
Firstly multiply by 3 in equation (i) and then add in equation (ii)-
<em> 3 x + 3 y = 75</em>
<em><u>- 3 x + 2 y = 25</u></em>
<em><u>5 y = 100</u></em>
<em>y = 20</em>
Put y = 100 in equation (i)-
We get,
<em>x = 25 - 20</em>
<em>x = 5</em>
<em>Therefore x = 5 and y = 20 .</em>
