Answer:
7 hours
Step-by-step explanation:
Step one:
given data
let the total charges be y and the number of hours be x
Company A charges
$60 reservation fee plus another $15 per hour.
so
y=60+15x----------1
Company B charges
$25 reservation fee plus another $20 per hour
y=25+20x------------2
Step two:
equate the 2 expressions above we have
60+15x=25+20x
collect like terms
60-25=20x-15x
35=5x
divide both sides by 5
x= 35/5
x= 7 hours
Find how many numbers are divisible by two and three, then place that number above the total number of items in the set as a fraction. Like this:
Answer:
The length of the thread which is left on the reel is 790 cm. Used = 210 cm.
Step-by-step explanation:
We have
3 / (x-5) - x/5
We make the GCF and we have
15/[ 5(x-5) ] - x(x-5)/[ 5(x-5)]
= [ 15 - x(x-5) ] [5(x-5)]
= [ 15 - x^2 + 5x] / [ 5 (x-5) ]
= [15 - x^2 + 5x]/[5x - 25]
An answer to your question is (15-x^2+5x)/(5x-25)
Answer:
7.92 miles (aprox.)
Step-by-step explanation:
1 hour = 60 minutes
19mph = 19miles/hour = 19miles/60 minutes
Proportions:
19 miles ⇔ 60 minutes
W miles ⇔ 25 minutes
W = 19*25/60
W = 7.92 miles (aprox)
