Answer:
There is no solution to the problem
Step-by-step explanation:
In order to find the solutions to the problem you can write the situation in an algebraic form.
You have that a number is equal to twice a smaller number plus 3. This can be written as follow:
(1)
where x is the number and y is the smaller number
Furthermore, the same number x is equal to twice the sum of the smaller number and 1, which can be written as follow:
(2)
To find the solution you equal the equation (1) with (2), and you solve for y:
You obtain an inconsistency, hence, the situation of the problem does not have solution
Answer:
63 divided by 3 is 21 so x=21
Step-by-step explanation:
Average speed of Alishia is 19 kilometers per hour
Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance. Speed is how fast something is going at a particular moment. Average speed measures the average rate of speed over the extent of a trip
Given :
Distance = 45.3 km
Time taken = 143 minutes = 143/60 =2.384 hours
∴ Average speed = 45.3/2.384 = 19 kilometers per hour
Thus the average speed of Alishia is 19 kilometers per hour.

Answer:
Option (D). 110°
Step-by-step explanation:
Since EB and AD are diameter,
= 
= 180°
= 180° -------(1)
And 
180° = 40° + 
= 140°
Since, 
= 140° [Given 
]
= 70°
From equation (1),
= 180° -
= 180°- 70°
Therefore, measure of arc(EDC) = 110°
Option (D) will be the answer.
