Step-by-step explanation:
Answer: there are 200 girls in the school.
Step-by-step explanation:
In a school, there is a ratio of 4 boys to 5 girls. The total ratio would be the sum of the proportion of boys and the proportion of girls. Therefore,
Total ratio = 4 + 5 = 9
If there are a total of 450 students, it means that the number of girls in the school would be
Proportion of girls/ total ratio × total number of students. Therefore,
The number of girls is
5/9 × 450 = 200
Answer:
B, C
Step-by-step explanation:
7 - x = 18
A.
7 - 2x = 18 - x
126 - 14x = 324 - 18x
We are nowhere near the solution.
B.
-x = 11
x = -11
This works.
C.
7 = x + 18
-11 = x
This works.
D.
25 - x = 36
-25 + x = -36
This does not help.
E.
7 = x + 18
0 = x + 11
We still do not have a solution.
Answer: B, C
L = 25
W = 13
H =18
SA = 2L*W + 2L*H + 2W*H
SA = 2*25*13 + 2*25*18 + 2*13*18
SA = 650 + 900 + 468
SA = 2018 square inches <<<< answer.
