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
Answer:
30+4=34
4·5-20
34+20= 54

Answer:
73
Step-by-step explanation:
Original number: XY
x = 3y - 2
10y + x = (10x + y) / 2 + 1/2
substitution: 10y + 3y - 2 = 13y - 2 = (10 * (3y - 2) + y) / 2 + 1/2
* 2 both sides and simplify: 26y - 4 = 31y - 19
31y - 26y = -4 + 19
5y = 15
y = 3
x = 7
Original number: 73
Answer:
(7) True
(8) true
(9) Neither true nor false
(10) False
(11) False
Step-by-step explanation:
We have given x = -3 and
We have to find that the expression given bellow is true or false
(7) xy= -2
So
Hence it is true
(8)
Hence it is true
(9) x+z = 4
We have not given value of z so we can say that it is true or false
So it is neither true nor false
(10)
So
Hence it is not true
(11)
Hence it is false
