Answer:
You can make 64 different sums (which includes a sum of $0 using none of the coins).
Step-by-step explanation:
The number of sums you can make is equal to:
⁶C₀ + ⁶C₁ + ⁶C₂ + ⁶C₃ + ⁶C₄ + ⁶C₅ +⁶C₆ = 1 + 6 + 15 + 20 + 15 + 6 + 1 = 64
Answer:
x=0, y=1.
Step-by-step explanation:
-8x+12y= 12
-2x-12y= -12 Adding these 2 equations:
-10x = 0
x = 0.
Plug this into equation 1:
-8(0) + 12y = 12
12y = 12
y = 1.
Answer:
x=8
Step-by-step explanation:
x + 1 = 9
Simplifying
x + 1 = 9
Reorder the terms:
1 + x = 9
Solving
1 + x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + x = 9 + -1
Combine like terms: 1 + -1 = 0
0 + x = 9 + -1
x = 9 + -1
Combine like terms: 9 + -1 = 8
x = 8
Simplifying
x = 8
Answer:
the answer is 3x minus 2 because when u combine the x terms it's 3x and 2 doesn't have any other like term
