Answer:
For every 15 students scoring in the 60's there were 9 students scoring in the 70's.
Step-by-step explanation:
Your first step would be to rewrite the numbers into an easier to understand form like fractions, 45/3 and 27/3. Then you divide both numbers by 3, so you get comparable numbers. 45/3= 15, 27/3=9.
The answer for this is n(3+2)
% damaged = (14 000/40000) * 100%
= 14/40 * 100%
= 0.35*100%
= 35%
Answer:
Step-by-step explanation:
A school has two computer labs and each lan has 30 computers. This means that the total number of computers is the sum of the number of computers in each lab
Total number of computers = 30+30 = 60
A total of six computers in the school or not working.
The expression that can be used to find the number of working computers in the school will be
Let the number of computers that are working be x
the number of computers that are working is total number of computers minus the number of computers that are not working be
The expression that can be used to find the number of working computers in the school will be
x = 60 - 6
x = 54
Equation: -1/2x + 1 = -x + 8
Work:
-x/2 + 1 = -x + 8
1 - x/2 = -x + 8
1 - x/2 = 8 - x
2 - x = 16 - 2x
-x = 16 - 2x - 2
-x = 2x + 14
-x + 2x = 14
x = 14
Final Answer:
x = 14
