Answer:
x ≈ 6.5
Step-by-step explanation:
We have the epresion 
and we want to find the value of 
.
Let's do it step-by-step
Step 1. Multiply both sides of the equation by 20
Step 2. use the reflexive property of equality: if 
then 
Step 3. Using a calculator we get that 
. Replacing that value we get
x ≈ 6.5
We can conclude that the value of x is approximately 6.5
Answer:
B) 100
Step-by-step explanation:
All 3 interior angles of a triangle add up to 180 so:
x + 25 + 55 = 180
x + 80 = 180
x = 180 - 80
x = 100

Answer:
The average speed is 24 km/h less than the top speed of the lorry.
Step-by-step explanation:
The top speed of the lorry is the highest speed reached during transit, while its average speed is the mean speed attained
Given:.
Top speed of the lorry = 90 km/h
Average speed of the lorry = 66 km/h
Then,
The difference between the speed reached = top speed - average speed
= 90 - 66
= 24 km/h
Therefore, the average speed is 24 km/h less than the top speed of the lorry.
