Well you need to convert the percentage into a decimal . E.g: if the tax was 7% it would be 0.7 in decimal form. Then , you need to multiply your decimal by the priced the product. Whatever that number is, is your tax. Add your tax to the price of the product and you have successfully found your whole price.
x is just a stand-in for an unknown/variable number, so we could use phrases like "a number," "a value," "an unknown," etc. Here, I'll use "a number." We can verbally refer to the result of subtraction as "the difference" as well, so we can write x - 6 in English as "The difference of a number and 6."
Answer: You need the unit price of how much it cost per min.
Step-by-step explanation:
First you have to find how much it costs for each min. So you divive 22.40 by 32 and you will get the answer for the cost of each min. Then Multiply the cost of each min by 38 and you should get the cost for 38 min.
Answer:
-2
Step-by-step explanation: All you have to do is insert the s and t value they gave you into the equation.
2s + 4t = ?
2(3) + 4(-2) = ?
6 + (-8) = ?
= -2
Step-by-step explanation:
First you must simplify the equation:
subtract 1 from both sides:
than divide both sides by -3, which switches the inequality sign:
This inequality means that all values of x greater than -2 work for the equation. because it is not 
, -2 is not included, so there will be a hollow circle there. than the inequality will have a line from that dot to the right so that all values of x that work for the inequality are on that line.
