<h3>
Answer: 0.85</h3>
Explanation:
If we start off with $100 and decrease by 15%, then we are decreasing by $15 since 15% of 100 = 0.15*100 = 15
We start with $100 and drop to 100-15 = 85. Dividing this over the original 100 gets us 85/100 = 0.85
Put another way, 100% - 15% = 1 - 0.15 = 0.85
The decimal multiplier for "decrease by 15%" is 0.85; this sort of thing is useful if you wish to apply multiple discounts to a product.
Side note: the 0.85 can be thought of as 85%, so the product's new value is 85% of its original value

Answer: Before going to the fair each person had $5.00
Step-by-step explanation: Audrey and her 3 friends equals 4 people in total
$2.00 each
2 x 4 = $8.00 to get in all together
$12.00 left over plus the $8.00 to get in is
$20.00 they all had together
now divide the 20 by the four of them, each person had $5.00
Answer:
+ 24x + 16
Step-by-step explanation:
If it is a square, all sides are equal. An area of a square would be side x side. You would multiply 3x + 4 and 3x + 4 together. I used the foil method (multiply first, then outside, inside, last) or (3x * 3x, 3x * 4, 4 * 3x, 4 * 4).
Answer:
Step-by-step explanation:
Matrix addition. If A and B are matrices of the same size, then they can be added. (This is similar to the restriction on adding vectors, namely, only vectors from the same space R n can be added; you cannot add a 2‐vector to a 3‐vector, for example.) If A = [aij] and B = [bij] are both m x n matrices, then their sum, C = A + B, is also an m x n matrix, and its entries are given by the formula
Thus, to find the entries of A + B, simply add the corresponding entries of A and B.
Example 1: Consider the following matrices:
Which two can be added? What is their sum?
Since only matrices of the same size can be added, only the sum F + H is defined (G cannot be added to either F or H). The sum of F and H is
Since addition of real numbers is commutative, it follows that addition of matrices (when it is defined) is also commutative; that is, for any matrices A and B of the same size, A + B will always equal B + A.
