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:
sln
3b-2a=7
3b-7=2a(divide by 2 both sides)
a=3b-7/2
Answer:
x = 198
Step-by-step explanation:
1/2x + 101 = 200.
Subtract 101 from both sides.
1/2x = 99
You want x by itself, therefore you have to get rid of 1/2. The opposite of diving by two, is multiplying by two.. therefore, you must multiply both sides by two.
x=99*2
x=198
