Answer:
x=2, y=1
Step-by-step explanation:
y=x-1
y=3-x
x-1=3-x
2x=4
x=2
Let's imagine that we have in the deck 52 cards. So what we need to do is to make a kind of "progression".So let me explain this by doing the procedure. we can use is like this:
4/52 * 3/51 * 2/50 * 1/49 =
<span>24 / 6497400 = </span>
<span>1 / 270725 </span>
<span>3.694e-6</span>
Archy: 15 gallons ... $23.85
1 gallon ...$ x = ?
x * 15 = 1 * 23.85 /15
x = 23.85 / 15
x = $1.59 per gallon
Joe: 16 gallons ... $24.48
1 gallon ... $ y = ?
y * 16 = 1 * 24.48 /16
y = 24.48 / 16
y = $1.53 per gallon
Result: Joe paid less per gallon.
The formula to solve for thee area of a square pyramid is [ V = 1/3 * b² * h ]
b² = base area (b = length of one side of the base)
h = height
The only option that as a base length of 12cm. and a height of 14cm. is the first option.
Solve for the volume if needed.
V = 1/3(12²)(14)
V = 1/3(144)(14)
V = 1/3(2,016)
V = 672cm²
Best of Luck!
It is hard to explain without a picture. You have the line graph and depending on what your numbers are, you place them where the teacher, (or paper) says too. You would then move two to the right, and one up. You would keep repeating that pattern until you got to the top of the graph. After that you would draw a strait line through it. If you are dealing with negative numbers, then depending on which one is negative, you would move two to the LEFT from the starting point and go one up. You repeat that pattern as well, then once you reach the top of the page you draw a line through it.
I hope this helped!
