Answer:
I will create a five by four matrix to indicate the costs of the products. The matrix will have five vertical columns and four horizontal rolls. The vertical columns will show the product categories and the total costs for all the products and decorations. The horizontal rolls will show the product costs, the decoration costs, and the total costs for each product category.
The size and shape of the matrix will be 5 by 4 with squared boxes.
Step-by-step explanation:
Products/Costs Hats Cards Teddy Total Costs
Product costs $2.50 $0.90 $3.10 $6.50
Decoration costs $1.50 $0.60 $1.70 $3.80
Total costs $4.00 $1.50 $4.80 $10.30
Answer:
x = 6
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
angle GKF because they are vertically opposite angle
B. Parallel faces
Not all sides need to be parallel and a polygon has only 1 face unless cut
Answer:
x = 4
Explanation:
For the right hand side:
log base 9 of 8 + log base 9 of (x-2) = log base 9 (8*(x-2))
= log base 9 of (8x-16)
For the left hand side:
2*log base 9 of x = log base 9 of x^2
Now, equating the two sides and solving for x:
log base 9 of (8x-16) = log base 9 of x^2
This means that:
x^2 = 8x - 16
x^2 - 8x + 16 = 0
(x-4)^2 = 0
Therefore:
x = 4
Hope this helps :)
