65 x6 = 390
80 x 3= 240
390+240 = 630
Answer:
Step-by-step explanation:
To prove: The sum of a rational number and an irrational number is an irrational number.
Proof: Assume that a + b = x and that x is rational.
Then b = x – a = x + (–a).
Now, x + (–a) is rational because addition of two rational numbers is rational (Additivity property).
However, it was stated that b is an irrational number. This is a contradiction.
Therefore, the assumption that x is rational in the equation a + b = x must be incorrect, and x should be an irrational number.
Hence, the sum of a rational number and an irrational number is irrational.
ANSWER
The x-coordinate of the solution to the system of equations is 1.
EXPLANATION
The given equations are:
y = -x - 2
and
y = 2x - 5.
We want to find the x-coordinate of the solution to the system of equations.
We equate the two equations to obtain an equation in x.
This implies that,
2x-5=-x-2
Group similar terms to obtain:
2x+x=-2+5
Simplify
3x=3
Divide both sides by 3.
x=1
The x-coordinate of the solution to the system of equations is 1
Here is your answer
=
REASON:
On solving the given two terms
-|2-5|= -|-3|
= -3 (since |-3|=3)
and,
(8-11)
= -3
Hence,
-|2-5| <u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>=</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>(8-11)

Answer:
$1,006.40
Step-by-step explanation:
Basic week = ($14.80/hour) * (40 hours) = $592.00
M-F overtime = ($14.80/hour ) * ( 1.25 ) * (12 hours) = $222.00
Sat overtime = ($14.80/hour ) * ( 1.5 ) * (2 hours) = $44.40
Sun overtime = ($14.80/hour) * ( 2 ) * (5 hours) = $148.00
Total wage = 592.00 + 222.00 + 44.40 + 148
Total wage = $1,006.40
