Answer:

x = 61 mph

the average speed on the level Road is 61 mph

Step-by-step explanation:

Let x represent Best's average speed on the level road. (In mph)

Best's average speed on the winding road = x-20

Given;

Total distance travelled = 571 miles

Time travelled on level road = 6 hours

Time travelled on winding road = 5 hours

Distance travelled = average speed × time taken

Total distance travelled can be written as

6 × (x) + 5×(x-20) = 571

6x+5x-100 = 571

11x = 571+100

11x = 671

x = 671/11

x = 61 mph

the average speed on the level Road is 61 mph

luke jogged a total of 56.5 miles last week. if luke jogged the same distance,d, each day for 3 days and half that distance on e
Leokris [45]
The algebraic equation used to answer this question is:
3d + 4(1/2d) = 56.5
This is because he ran d, the distance, three times that week. For the rest of the four days, he ran 1/2 the distance, or half d.
To find the answer, you first distribute:
3d + 2d = 56.5
Add like terms:
5d = 56.5
Divide both side by 5:
5d/5 = 56.5/5
d = 11.3
On the first three days, Luke jogged 11.3 miles. On the remaining days, where he jogged 1/2d, Luke jogged 5.65 miles.
Hope this helps!

What is the X-in intercept of the line 6x + y = 18
Keith_Richards [23]

\boxed{x=3}

Step-by-step explanation:

The Standard Form of the equation of line is given by:

Ax+Bx=C \\ \\ For \ A, \ B, \ C\ Real \ Constant \\ and \ A>0

So:

6x+y=18 \\ \\ is \ written \ in \ standard \ form

The x-intercept can be found setting y=0:

6x+(0)=18 \\ \\ Isolating \ x: \\ \\ 6x=18 \\ \\ \boxed{x=3}
