Mathematics

mojhsa [17]2 years ago

Answer:

x = 34

Step-by-step explanation:

This is a straight line so the sum of angles must be 180°

4x + 20 + x - 10 = 180 add like terms

5x + 10 = 180 subtract 10 from both sides

5x = 170 divide both sides by 5

x = 34

To calculate each angle we replace x with the value we found

4x + 20 ➡ 4×34 + 20 = 156

x - 10 ➡ 34 - 10 = 24

➷ Work out the time for Cardiff to Swansea:

time = distance/speed

Substitute in the values:

time = 69/60

Solve:

time = 1.15 hours = 69 minutes

Add together the total time and distance:

72 + 69 = 141

48 + 69 = 117

speed = distance/time

speed = 141/1.95

speed = 72.3 km/h
