1) X+12
2) 2x-5
3) 40-x
4) (x1/3)(12)
5) x0.25
6) 2x:4y
7) 12(x-1)
8) 3[(x)(-8)]
9) 7(2x+3)
10) (x-30)+(y-30)
Let the no. of $10 bills be x, the no. of $5 bills be 2x, and the no. of $20 bills be y.
<span>A cashier collects 124 bills => x + 2x + y = 124 => 3x +y =124
</span>totaling $920 dollars => ($10)(x) + ($5)(2x) + ($20)(y) = $920 => 20x + 20y = 920
Now you got 2 equations :
3x +y =124 &
20x + 20y = 920
3x +y =124 => y=124-3x
Then Sub y=124-3x into 20x + 20y = 920,
ie. 20x + 20(124-3x) = 920
20x + 2480 - 60x = 920
2480 - 40x = 920
2480 - 920 = 40x
1560 = 40x
x = 39
Answer:
p= $10,000
Step-by-step explanation:
Write out the equation: 5500/p = 55/100
Cross multiply: 55p = 550,000
Divide: 550,000/55
Solve: 10,000
