Answer:
total cost = $ 81
Step-by-step explanation:
It is given that the fixed cost is $ 39
and the cost per minute is $0.07
Let us assume the number of minutes used be x
we have
total cost = cost per minute × number of minutes used + fixed cost
we plug the given values, so we have
we need to find the total cost for 10 hours used
x= 10 hours = 10(60) minutes = 600 minutes
so we have total cost for x= 600 minutes
hence the total cost = $ 81
<span>It is best to rewrite the expression using addition before identifying the terms because when you have subtraction figures, those would make a term negative. As a result, it would be easier to accidentally misinterpret a term that is negative as positive when evaluating an expression. Rewriting it using addition would put the negative terms in parenthesis and make it easier to transpose those terms and ensure correct identification and use.</span>
Answer:
x = 20
Step-by-step explanation:
The sum of the three angles in the diagram is 180 degrees since they form a straight line
x + 100 + 3x = 180
Combine like terms
100 +4x = 180
Subtract 100 from each side
100+4x-100 =180-100
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
