We observe that 20 is 4 more than twice 8. This suggests the time is 1 hour and the rates are
... scooter: 20 mi/h
... bicycle: 8 mi/h
_____
You can let b represent the rate of the bicycle in miles per hour. Then we have (for time in hours and distance in miles) ...
... time = distance/speed
... time = 20/(2b+4) = 8/b
... 20b = 8(2b+4) = 16b +32
... 4b = 32
... b = 8
The rate of the bicycle is 8 mph; that of the scooter is 2*8+4 = 20 mph.
Answer:
Draw an open circle on 3 and shade to the left.
Step-by-step explanation:
Given:
The inequality given is:
In order to solve for 'x', we add 6 on both sides of the inequality. This gives,
Therefore, the solution is 'x' less than 3.
So, 'x' includes all the values that are less than 3 and excluding 3 as the inequality sign is less than.
So, on a number line, the values that are less than 3 are to the left of 3. So, we shade to the left. Also, 3 is excluded from the solution. So, we use an open circle as shown below.
So, the first option is the correct option.
Hey there,
It would be devising a plan
Hope this helps :))

Answer:
Step-by-step explanation:
Cost of meal = $6
Amount of tip = $0.90
To calculate the tip as a percentage of the total cost, divide amount
of tip by the total cost and multiply the result by 100;
Percentage of tip = (amount of tip/cost of meal ) *100
= (0.90 / 6)*100
= 0.15 *100
= 15%
Therefore Miss Holman tipped the waitress 15% of the total cost of the meal
