Answer:
a = A/πb
Step-by-step explanation:
To solve this subject of the formulae given that A = πab.
<u>solution</u>
A = πab
the next step is to look for a unique way to get rid of the variables disturbing "a" from standing alone. this variables are π and b, we need to detach dem from a
A = πab
divide both sides by πb
A/πb = πab/πb
A/πb = a
a = A/πb
therefore the value of a in the fomular A = πab is evaluated to be a = A/πb
1 ton = 2,000 pounds
3 tons = 6,000 pounds
$480/6,000 = 0.08
per pound is $0.08
Let x = amount for dog
let 2/3x-5 = amount for cat
x + 2/3x-5 = 195 combine x's
1 2/3x or 5/3x
5/3x-5 =195 add 5 to both sides
5/3x = 200 multiply both sides by 3
5x = 600 divided both sides by 5
x = 120
the cost of the dog is $120.00
Answer:
Step-by-step explanation:
subtract m from both sides and you get - 3/4m
divide 2/3 divided by -3/4
-8/9
