okay... THE ANS IS 5/35 IS THE RIGHT ONE
Add 6.9 to both sides.
This is the new equation: 4.8y=10.08.
Next, divide both sides by 4.8.
new equation: y=2.1
Hope this helped!!
Answer:
Step-by-step explanation:
<u>Volume of a Pyramid</u>
The volume of a pyramid with base area Ab and height H is given by:
If the base is a square of side length L, then its area is:
Thus, substituting the above equation in the first:
The side length is L=10.9 m and the height is 4.7 m, thus the volume is:
The first one is correct because the form is y-y1=m(x-x1)
Two equations can be generated from the equation above, one for Package A and the other for Package B.
(Package A) 3x + 2y = 18
(Package B) 8x + 6y = 50
Solving simultaneously for the values of x and y gives, x = 4 and y = 3. Hence, each birthday card costs $4.
