It’s an expression that compares two or more numbers. Ex; 3:10.
The publisher makes (22.75 -12.00) = 10.75 per book, so to cover the 21,499 fixed cost, must sell
.. 21,499/10.75 = 1999.9
books
Sales revenue will equal production costs when the publisher produces and sells 2000 books.
In the second equation:
Subtract 8x from both sides.
2z = 22 - 8x
Divide 2 on both sides.
z = 11 - 4x
Plug this into the first equation.
-66 - 2(11 - 4x) = -196
-66 - 22 + 8x = -196
Combine like terms.
-88 + 8x = -196
Add 88 to both sides.
8x = -108
Divide 8 on both sides.
x = -13.5
Put this into the second equation.
8(-13.5) + 2z = 22
-108 + 2z = 22
Add 108 to both sides.
2z = 130
Divide 2 on both sides.
z = 65
and
x = -13.5
Hope this helps!
When you multiply terms with like bases you add the exponents together. The base stays the same. When you divide terms with like bases you subtract the exponent of the denominator from the exponent of the numerator. This is called getting the power of a power.
63 x 4 = 2x2=3 - 17? Simplified form of this expression: The chosen topic is not meant for use with this type of problem.
So instead I will simplify the matrix, if you simply the matrix, the ANSWER will be: 252 = 2x^2 = -14
