Answer:
Step-by-step explanation:
Product of 5 and a number: 5n
Six more than that would be 5n + 6
Finally, "six more than the product of 5 and a number, decreased by one" would be
5n + 6 - 1, or 5n + 5
Answer:
2
Step-by-step explanation:
Since there are four negative signs, we have -1 multiplying each other 4 times, multiplying by positive 2. This is then 1 * 2, which is 2.
Answer:
5:00 pm
Step-by-step explanation:
Let
x -----> the umber of hours
y ----> the total distance in miles
we know that
The distance is equal to the speed multiplied by the time
Find out the distance traveled by Ariel at 11:00 am
11:00 am-09:00 am=2 hours
45(2)=90 miles
so
<em>Ariel's linear equation is</em>
----> equation A
<em>Ariel's brother linear equation is</em>
----> equation B
Equate equation A and equation B
![60x=45x+90](https://tex.z-dn.net/?f=60x%3D45x%2B90)
Solve for x
![60x-45x=90](https://tex.z-dn.net/?f=60x-45x%3D90)
![15x=90](https://tex.z-dn.net/?f=15x%3D90)
![x=6\ hours](https://tex.z-dn.net/?f=x%3D6%5C%20hours)
Adds 11:00 am + 6 hours=17:00 =5:00 pm
