e-lub [12.9K]
Ok so we are given 6000 and I think that would be I
We are also given 9000, and I think that would be p
Also we are given 4.1% or 0.041 and I think that would be r
So the formula is 
I = prt
6000 = 9000*0.041*t                        So we are trying to figure out t, time
6000/0.041 = 146341.463

A train travels 90 3/5 miles in 3/4 of an hour. What is the average speed, in miles per hour, of the train? I also have to show
OverLord2011 [107]

Answer:

120 \frac{4}{5} or 120.8 miles per hour

Step-by-step explanation:

We first convert the distance into an improper fraction to facilitate calculation.

90 \frac{3}{5} = \frac{90\times 5 + 3}{5} = \frac{453}{5}

Average speed

= distance/time

= \frac{\frac{453}{5}}{\frac{3}{4}}miles per hour

= \frac{453}{5} \times \frac{4}{3} miles per hour

= \frac{604}{5} miles per hour

= 120 \frac{4}{5} miles per hour or 120.8 miles per hour

PLEASE PLEASE PLEASE HELP ME WITH ALGEBRA 1 PLEASE!?!?!?!?!!!?!?!?!?!?! I WILL GIVE LOTS OF POINTS AND BRAINLEST PLEEEEEEEEEEEEE
jekas [21]

Answer:

  • there are no solutions (lines do not intersect)
  • there is one solution (lines intersect at one point)
  • there are an infinite number of solutions (lines overlap—are the same line)

Step-by-step explanation:

"A system of linear equations" covers a lot of territory. In Algebra 1, it usually means two linear equations in two unknowns. Each of those equations will graph as a line on a coordinate plane.

A solution is a point that satisfies all the equations. That is, it is a point that is on all the lines described by the system of equations.

The geometry of lines on a plane comes into play with regard to solutions.

  • The lines may be parallel, hence never intersect. (<em>No points</em> will be on all the lines.)
  • The lines may intersect at <em>one point</em>.
  • The lines may be the same line, overlapping, identical, coincident, consisting of <em>all the same points, an infinite number</em>.
