5/6 is the answer because you plug in your numbers to the variables which is 5/2x3 so you simplify it down to 5/6
The easiest way to solve this is to take the amount of each coin and multiply it by its value. Afterwards add each total together to determine the amount of money that Ann has.
145 pennies X $0.01 = $1.45
42 dimes X $0.10 = $4.20
12 quarters X $0.25 = $3.00
$1.45 + $4.20 + $3.00 = $8.65
Therefore Ann has $8.65
I would love to help! What's the question?
Answer:
18
Step-by-step explanation:
First, I'm assuming AB=4=4x-2 was a typo and it's supposed to be AB = 4x - 2
AB=BC
AB = 4x - 2 BC = 3x + 3
4x - 2 = 3x + 3
Solve for x Add 2 to each side
4x - 2 = 3x + 3
4x - 2 + 2 = 3x + 3 + 2
4x = 3x + 5 Subtract 3x from each side.
4x - 3x = 3x- 3x + 5
4x - 3x = 5
x = 5
Now plug back in to the original equations
AB = 4x - 2 BC = 3x + 3
AB = 4 (5) - 2 BC = 3(5) + 3
AB = 20 - 2 BC = 15 + 3
AB = 18 BC = 18
So AB is 18
