Mathematics

Answer:

n = 0

Step-by-step explanation:

Multiply parenthesis by 3 and get:

1.) 18 + 9n = 5n + 18 + 3n

Then cancel the equal terms:

9n = 5n + 3n

Collect like terms:

9n = 8n

Move variable to the left:

9n - 8n = 0

n + 0

Plugin the value of 0 into x:

3 (6 + 3 x 0) = 18

5 x 0 + 3 x 0 + 18 = 18

*If the plugged in value have the same result than the answer is correct because 18 + 18.

Jabes travelled 3406km in 8days. if he travelled the same distance every day, how many kilometers did he travel per day?
lisabon 2012 [21]

Jabes travels 425.75km per day.

Unit rate is the amount of a certain item related to a single unit of another item.

In the question, we are given that Jabes traveled 3406km in 8 days

We have to find the distances that Jabes travel per day which will be the unit rate of distance per day.

The total distance that jabes traveled in 8 days = 3406 km

Thus, the distance per day jabes traveled can be calculated as:

8 days ⇒3406 km

or, 1 day⇒ 3406/8days = 425.75km

Thus,jabes traveled 425.75 km per day, using the unit rate.

Write the equation in slope-intercept form of a line that has a slope of 1/3 and passes through the point (-6, 0).
Vesna [10]

Answer: y = 1/3x +2

Step-by-step explanation:

The equation of line in slope - point form is given as:

y - y_{1} = m ( x - x_{1} )

m = 1/3

y_{1} = 0

x_{1} = -6

substituting into the formula , we have

y - 0 = 1/3 ( x - {-6} )

y = 1/3 (x+6)

y = 1/3x +2
