Answer:

x = 25

Step-by-step explanation:

120 = 70 + 2x

120 - 70 = (70 - 70) + 2x

50 = 2x

50/2 = 2x/2

x = 25

Write the equation of the line, given the y and x-intercepts:

kolezko [41]

Answer:

The answer to your question is: 161x + 17y - 391 = 0

Step-by-step explanation:

Data

y-intercept = 23 Get the points (0, 23)

x- intercept = 4.75 (4.75, 0)

4.75 = 17/4 (17/4, 0)

slope

m = (y2 - y1) / (x2 - x1)

m = (0 - 23) / (17/4 - 0)

m = -23 / 17/4

m = - 161 / 17

equation

(y - y1) = m (x - x1)

( y - 23) = -161 / 17 (x - 0)

y - 23 = -161/17 x

17(y - 23) = -161x

17y - 391 = -161x

161x + 17y - 391 = 0

Two skiers are 30 kilometers apart and head towards each other. They meet in 2 hours. If the second skier is 5 kilometers per ho

DENIUS [597]

Answer:

Speed of first skier = 5 km/h

Speed of second skier = 10 km/h

Step-by-step explanation:

Given:

Distance between skiers = 30 km

Time after which they meet = 2 hours

Second skier is 5 km/h faster than the first skier.

To find speed of each skier.

Solution:

Let the speed of first skier be in km/h = $x$

<em>Distance covered in km 2 hours will be = $Speed\times time=x\times 2=2x\ km$ </em>

Speed of second skier in km/h can be given as = $x+5$

<em>Distance traveled by second skier after 2 hours will be = $Speed\times time=(x+5)\times 2=(2x+10)\ km$ [Using distribution]</em>

Since, the skiers were 30 km apart initially, so the total distance covered by both of them when they meet after 2 hours will be = 30 km

Thus, we have:

$2x+2x+10=30$

Solving for $x$

$4x+10=30$

Subtracting both sides by 10.

$4x+10-10=30-10$

$4x=20$

Dividing both sides by 4.

$\frac{4x}{4}=\frac{20}{4}$

$x=5$

Speed of first skier = 5 km/h

Speed of second skier = $5+5$ = 10 km/h
