Answer:
B
Step-by-step explanation:
To determine if x = 6 is a solution, substitute x = 6 into the left side of the equation and if equal to the right side then it is a solution.
2(6) - 5 = 12 - 5 = 7 ≠ 1
Then x = 6 is not a solution of the equation since a false statement results after replacing x with 6 (B)
Add 1, then add 2, then add 3, then 4, then 5, then 6.
25/4 is the right answer have a good day :)
Answer:
∠3 is 70°
Step-by-step explanation:
∠1 is 50° since it is across from another 50° angle
and then you use the equation x+25+2x+50=180 to find x
x then equals 35°
you then use the alternate interior angle theorem to say that ∠3 is 2x, or 70°
In this question, it is necessary to first check all the details that are already provided in the question. Then after they are noted down the final thing required is to find the answer to the question by correct calculations.
Distance for which the truck traveled = 280 kilometers
Time taken to travel the given distance = 4 hours.
Then
Speed of the truck = Distance traveled/Time taken
= 280/4 km/hr
= 70 km/hr
So the truck was traveling at a speed of 70 kilometers per hour. This is the answer to both the questions that have been put up. So there is no need for any kind of second calculation.
