Answer:

<h2>2.5 hours</h2>

Step-by-step explanation:

Step one:

given data

for train one

speed= 50miles per hour

for train two

speed= 60miles per hour

the total distance between both trains=275miles

Step two:

the expression for speed= distance/time

so that, distance= speed*time

let the time be t

we are going to combine both distances

train one distance =50t

train two distance =60t

Hence total distance

50t+60t=275

110t=1=275

t=275/110

t=2.5 hours

<u>It will take 2.5 hours</u>

The total cost of a jacket and a pair of shoes was $95.11. If the price of the jacket was $2.79 less than the pair of shoes, wha
vovangra [49]

The <em>cost of the jacket</em> purchased using the <em>System of equation</em> is $46.16

<u>Given the cost prices</u> :

  • Total cost = $95.11
  • Cost of shoes = x
  • Cost of jacket = x - 2.79

<u>We could set up an equation relating the cost of each item to the total Cost : </u>

<em>Total cost = cost of jacket + cost of shoes</em>

95.11 = x - 2.79 + x

95.11 = 2x - 2.79

95.11 + 2.79 = 2x

97.90 = 2x

x = 97.90 / 2

x = 48.95

Cost of jacket = $48.95 - 2.79 = $46.16

Therefore, Cost of jacket is $46.16

Find the length of X in simplest radical form with a rational denominator
Darya [45]

Answer:

x = \sqrt 6

Step-by-step explanation:

Given

The attached triangle

Required

Find x

Considering angle 30 degrees,

Opposite = \sqrt{2

Adjacent = x

Using the tangent formula:

tan\ 30 = \frac{\sqrt 2}{x}

Make x the subject

x = \frac{\sqrt 2}{tan\ 30}

x = \frac{\sqrt 2}{1/\sqrt 3}

x = \sqrt 2 * \sqrt 3

x = \sqrt 6

An equation is shown below: 3(2x − 7) = 9
Katen [24]

Answer:

1 solution

Step-by-step explanation:

3(2x-7)=9

dustribute: (3)(2)+(3)(-7x)=9

6+-21x=9

subtract 6 from both sides: -21x=3

Divide both sides by -21: x=-1/7

so your 1 solution is x = - 1/7
