Find the value of x for which the lines a and b are parallel.
siniylev [52]

Answer:

x = 19

Step-by-step explanation:

148 and 7x+15 are alternate interior angles and alternate interior angles are equal when the lines are parallel

148 = 7x+15

Subtract 15 from each side

148-15 = 7x+15-15

133 =7x

Divide each side by 7

133/7 =7x/7

19=x

IgorLugansk [536]

The both started at 11.00 a.m then they will meet at 11:15 a.m

We have given that

Two turtles, which are 750 meters apart and the are moving towards each other

average speed of 1 km/h, and the other travels 1 km/h faster

Therefore we have to find When will the turtles meet.

First turtle travels at an average speed of 1 km/h.

Thus; v₁ = 1 km/h

Second turtle travels at an average speed of 1 km/hr faster than the first.

Thus; v₂ = 2 km/h

Since second turtle is moving 2 times faster than the first one, it means the second turtle will cover 2/3 of the total distance while the first will cover 1/3 of the total distance at the point they will meet.

What is the value of 1 kilometre in meter

1 km=1000 meter

So,

Distance covered by turtle 2

= 2/3 * 0.750 = 0.5 km

Time = distance/speed

Time = 0.5/2

Time= 0.25 hours \\\\ Time= 15 minutes

Since they both started at 11.00 a.m then they will meet at 11:15 a.m
