Equation in standard form:
Ax+By=C
We have:
3x-5+y=2y-4
3x+y-2y=-4+5
3x-y=1
Therefore:
A=3
B=-1
C=1
Answer: the equation in standard form would be: 3x-y=1; and the values of A, B and C would be: A=3; B=-1 and C=1.
The total cost of the TV is: $181.57
Work: 195.72 x 0.20 (20%) = 39.14
195.72 - 39.14 = 166.58 <-- Was for the discount now you have to do the tax.
Now Tax, 166.58 + 14.99 = 181.57
Hope this helps!
First, multiply 50*3 to get the answer in feet which is 150 ft.
Then, divide 150 ft by 60 which would be 2.5 ft per second.
You have 5 quarters which equals 25 cents each. Which in total comes to $1.25.
You have 15 dimes which is worth 10 cents each.
Which in total comes to $1.50.
$1.50
+$1.25
=$2.75
