Answer:
44
Step-by-step explanation:
Let x and y be the total number of questions in part 1 and part 2 exams respectively.
For part 1:
Number of correct question = 4/5 of the total number of question in part 1
For part 2:
Number of corrected question = 2/3 of total number of question in part 2
So, the total umbers of the questions on Stephanie's exam
=x+y
=20+24
=44
Hence, the total umbers of the questions on Stephanie's exam was 44.
D because rational numbers CAN be negative
There are 12 more of white and blue cars than silver and red cars
Step-by-step explanation:
Step 1 :
Number of black cars counted by Ed = 23
Number of red cars counted by Ed = 9
Number of blue cars counted by Ed = 17
Number of white cars counted by Ed = 25
Number of silver cars counted by Ed = 21
We need to determine how many more white and blue cars are there than silver and red cars
Step 2 :
Total of white and blue cars = 25 + 17 = 42 cars
Total of sliver and red cars = 21 + 9 = 30 cars
Difference = 42 - 30 = 12 cars
Hence there are 12 more of white and blue cars than silver and red cars
Step 3 :
Answer :
There are 12 more of blue and white cars than red and silver cars
The answer to that is 0.775
Answer:
x=4
Step-by-step explanation:
-x+4=2x-8
4=2x-(-x)-8
4=2x+x-8
4=3x-8
3x=4+8
3x=12
x=12/3
x=4
