Answer:

fourth option

Step-by-step explanation:

Given the 2 equations

y = 2x - 3 → (1)

x + y = 18 → (2)

Substitute y = 2x - 3 into (2)

x + 2x - 3 = 18

3x - 3 = 18 ( add 3 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Substitute x = 7 into (1) for corresponding value of y

y = 2(7) - 3 = 14 - 3 = 11

Solution is x = 7, y = 11

On a 4 1 2 hour trip, Leslie drove 2 3 of the time. For how many hours did Leslie drive?
valentina_108 [34]

Answer:

She drove 3 hours

Step-by-step explanation:

Leslie drove 2/3 of the 4 1/2 hours trip.  To determine how long she drove, multiply these numbers together.

2/3 * 4 1/2

We need to change the second number to an improper fraction

4 1/2 = (2*4 +1)/2 = 9/2


2/3 * 9/2 = 9/3 = 3


She drove 3 hours

How many different four-digit numbers can be formed with the numbers 7; 4; 5; 1; 2; 9; and 8?
vodomira [7]
Two answers are possible.
One is with the repetition of digits.
The other is without repetition of digits.
ANSWER 1: With Repetition
Numbers: 1,2,4,5,7,8
There are 4 digits __ __ __ __
1st digit can be filled by any of the 6 numbers.
Similarly 2nd, 3rd and 4th digits.
Hence each digit will have 6 possibilities.
Therefore no.of 4 digit numbers that can be formed are 6 x 6 x 6 x 6 = 1296
ANSWER 2: Without Repetition
4 digits __ __ __ __
Now the first digit can be filled by any of the six numbers. Therefore there are 6 possibilities
The second digit will have only 5 possibilities as one of the numbers gets used up by the 1st digit.
Similarly the 3rd and 4th digits will have 4 and 3 possibilities respectively.
Therefore no.of 4 digit numbers that can be formed are 6 x 5 x 4 x 3 = 360
