Answer:
1.425.
Step-by-step explanation:
1 .425 is the only one which can be written as a fraction ( 1425/ 1000).
π is a non repeating decimal which goes on without bounds.
So is √50 (try entering it on your calculator).
√-4 : there is no real number whose square root is negative.
One.
To solve this, first combine like terms.
6x + 4x - 6 = 24 + 9x
10x - 6 = 24 + 9x
Then move all like terms to one side.
10x - 9x = 24 + 6
x = 30
Answer:
$124
Step-by-step explanation:
If the tax value of a item that costs $310 before tax is $25, we can calculate the tax percentage by dividing the tax costs by the item value without taxes:
tax = 25/310 = 0.0806
So, for the second item, if the tax costs were $10, we can calculate the item value (this value will be called X) with the following equation:
tax = 10/X = 0.0806 -> X = 10/0.0806 = $124
Another way of solving this problem, is by rule of three:
tax of 25 for an item of $310,
tax of 10 for an item of $X
25/10 = 310/X -> X = 310*10/25 = $124
