<span>A freight train completes its journey of 150 miles 1 hour earlier if its original speed is increased by 5 miles/hour. What is the train’s original speed?
***
let x=original speed
x+5=increased speed
travel time=distance/speed
..
lcd:x(x+5)
150(x+5)-150x=x(x+5)
150x+750-150x=x^2+5x
x^2+5x-750=0
(x-25)(x+30)=0
x=25

A rocket is divided into three sections. The top section is one-eighth the length of the bottom section. The middle section is o
Ahat [919]

Answer:

312 ft

Step-by-step explanation:

The steps are as follows :

1. The problem can be described as an equation

x +  \frac{1}{2}x +  \frac{1}{8}x = 312

2. Convert all values on the left side into their equivalent fractional values

\frac{8}{8}x  +  \frac{4}{8}x +  \frac{1}{8} x = 312

3. Combine like terms

\frac{13}{8} x = 312

4. Multiply both sides by the reciprocal of 13/8 to isolate variable X

concept \:  \:  \: ({ \frac{8}{13}  \times  \frac{13}{8} }) = 1

\frac{8}{13} \times  \frac{13}{8}x  = 312 \: \times  \frac{8}{13}

5. Simplify

x = 192

6. Check answer by using it in the original equation

(192) +  \frac{1}{2}(192) +  \frac{1}{8} (192) = 312

Joanne has a goal of buying a townhome and saved for 5 years. She expected to have the down payment of $15,000 saved by now but
serg [7]

Answer:


Step-by-step explanation:

Average amount saved per year = \frac{15,000}{5}

                                                      =$3000

So on average Joanne has saved $3000 per year. She only needs $2000 more which will not even take a year to save.

How many months it will take to save $2000:

\frac{12}{3000} \times2000

= 8 Months.

It will only take Joanne 8 moths to save $2000.

If she really wants to buy the home now she can always go for a home loan scheme for $2000. Any interest rate less than 50% per year is fine as she can save $3000 per year.
