Part C. 19 and 8 are the 2 factors
WORK: since 56 + 96 = 152, and 152 goes into 8 19 times.
Answer:
2hours
Step-by-step explanation:
Given data
Company A
charges a fixed amount of $10 plus $8 per hour
let the number of hours be x
and the total be y
y= 10+8x----------------1
Company B
charges a fixed amount of $6 plus $10 per hour for a one-person kayak.
let the number of hours be x
and the total be y
y= 6+10x----------------2
Equate 1 and 2 above
10+8x= 6+10x
collcet like terms
10-6= 10x-8x
4= 2x
x= 2hours
Hence after 2 hours the charges will be the same
Answer:
The 2 and 3
Step-by-step explanation:
<h3>
Answer: 82</h3>
====================================================
Explanation:
Let A be the tens digit and B be the units digit
We can write the number as AB. So if A = 9 and B = 2 for instance, then the number is AB = 92. Keep in mind I'm not multiplying A and B here.
"The unit digit is a prime" means B could be any of these values {2,3,5,7}. We only list the single digit primes. The value 1 is not prime.
Now multiply each of those items by 4
4*2 = 8
4*3 = 12
4*5 = 20
4*7 = 28
Of those results, only 4*2 = 8 leads to a single digit answer.
This must mean that A = 8 and B = 2
Therefore the number is AB = 82.
What is the solution to the system of equations?
y= 1.5x - 4
y = -x
