x = 1 because -7(3x + 4) must be -49 so 3x + 4 must me 7 so x = 1
Complimentary angles add up to 90 degrees and supplementary angles add up to 180 degrees...
Complementary angle = 90-52= 38°
Supplementary angle = 180-52= 128°
Simplified expression that represents the cost of renting 6 scooters is 18 j +30
<u>Step-by-step explanation:</u>
Given data:
The cost of renting of a scooter is represented by 3j +5
So, from that, we can say in general,
The cost of renting of n scooters is represented by
But according to given, the value of n is 6. i.e. to find the cost for six number of scooters. We can calculate now as follows
So, the cost of renting of a scooter is represented by
The speed is the distance covered by an object at a particular time. The distance that is covered by the vehicle is 3,391 miles.
<h3>What is speed?</h3>
The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Speed = Distance / Time
Given that the journey took 9 days. Therefore, the time in hours will be equal to,
Time = 24 hours/day × Number of days
= 24× 9
= 216 hours
Also, given that the speed of the vehicle is 15.7 miles per hour, the number of hours for which it travels is 216 hours.
Distance = Speed × Time
= 15.7 miles/hour × 216 hours
= 3,391.2 miles
Hence, the distance that is covered by the vehicle is 3,391 miles.
