Stack 1 : 2^0 = 1 quarter.
Stack 2 : 2^1 = 2 quarters.
Stack 3: 2^2 = 4 quarters.
Stack 4: 2^3 = 8 quarters.
Stack 5 : 2^4 = 16 quarters.
Stack 6: 2^5 = 32 quarters.
1 + 2 + 4 + 8 + 16 + 32 = 63
Answer: She used 63 quarters.
That would be 6,12,18,24,30
10x+3y=43
-9x-y=-20
From second equation,
y=-9x+20
Substitute third equation into first equation,
10x+3(-9x+20)=43
10x-27x+60=43
-17x=43-60
-17x=-17
x=1
y= -9+20= 11
Option B
Answer:
222 small ones and 74 middle ones
Step-by-step explanation:
The computation is shown below:
Let us assume medium ones be x
so the small ones be 3x
And, the total is 296
So, the equation is
x + 3 x = 296
4x = 296
Medium ones = x = 74
And, the small ones is = 3 × 74
= 222
