Step-by-step explanation: 25 blue chips and 35 red
Answer:
Step-by-step explanation:
Example
With numbers
18+4=22
18+4−4=22−4
18=18
With variables and numbers
x+4=22
x+4−4=22−4
x=18
We subtract 4 from both sides. Example
Which of the following numbers is a solution to the equation? x = 2, 7, or 8?
14−x=7
Here you are given the numbers 2, 7 and 8. One of these numbers will satisfy the equation. If you don't know the solution right away, you can investigate which of the given numbers gives results in the correct answer by plugging in the different values of x.
Answer: x=7
Example
8x=64
8⋅x=64
Which number should you multiply 8 by to get a product of 64? By using the multiplication table, we know that the number is 8.
8⋅8=64
When we solve an equation, we figure out what value of x (or any other variable) makes the statement true (satisfies the equation).

A square matrix is invertible if its determinant is not zero.
The determinant for this matrix is
so it does not have an inverse because its determinant is zero.
That reminds me, I have to go check if my kid's tent is ready for camp.
The volume of this triangular prism tent will be the area of its base times its length, six feet here. The area of the triangle is of course half the base times the height.
If we call the height h we get
36 = (1/2) (4)(h)(6)
36 = 12 h
h = 3 feet
Most folks can sit in a 3 foot tall space, but it's a little tight, especially with your head squeezed up there near the apex.
