A single point has no dimension.
A line of multiple points will have a length.
Points that creates a plane has two dimensions. length and width
Points that creates a solid shape has three dimensions. length, width, and height
A. 2x+y=25; x+y=20
x represents cheese wafers and y represents chocolate wafers.
B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20
Add equations
x=5
Plug x in
5+y=20
y=15
Final answer: 5 cheese wafers, 15 chocolate wafers
y=(-2x)+5
Step-by-step explanation:
Use the Pythagorean Theorem
6 feet and 14 feet are the "legs" and the ladder length is the hypotenuse.
hypotenuse^2 = 6^2 + 14^2
hypotenuse^2 = 36 + 196
hypotenuse^2 = 232

ladder length = 15 feet

To find the answer, you will need to divide the total number of balloons by the number of balloons in a pack.
275 ÷ 2 = 137.5
Because you can't buy half of a package, Celia should probably buy 138 packages.
