Answer:
The smallest value of the three numbers would be 9.
Step-by-step explanation:
In order to find this, set the smallest number as x. Then you can set each of the next integers as x + 1 and x + 2. Now we can total all three numbers and set equal to 30 to solve for x.
x + x + 1 + x + 2 = 30
3x + 3 = 30
3x = 27
x = 9
Considering 32 outside the square root .
Here we have to combine like terms, and like terms are 8 , 98 ,3, 32 and 5 square root x and 6 square root x .
We need to remove the parenthesis and since there is a minus sign outside the second parenthesis , so we have to flip the sign of the terms of second parenthesis. THat is
=
And that's the final answer .
Answer:
Step-by-step explanation:
The given augmented matrix is
Here, we need to perform the row operation and replace in the above matrix.
So, divide each element of in the given matrix and other elements remain same.
Therefore, the required matrix is .

The hours worked at the babysitting job is 6 hours.
The hours worked at the barber shop is 3 hours.
<h3>What are the hours worked at the babysitting job?</h3>
Given the two linear equations:
x + y = 9 equation 1
15x + 9y = 117 equation 2
Multiply equation 1 by 9
9x + 9y = 81 equation 3
Subtract equation 3 from 1
36 = 6x
x = 6
<h3>What are the hours worked at the barber shop?</h3>
Substitute for x in equation 1
6 + y = 9
y = 9 - 6
y = 3 hours
