We know that pupils are students
Students = S
boys = B
Teachers = T
So....
S = 8T
Boys = 3G
T = B - 70
Since there is 8x students than teachers, I did Boys = 6x and girls = 2x
I'm going to use this next: S = 8T
8x = 8(B -70)
8x = 8(6x - 70)
8x = 4x - 560
x = 14
We know there is 8x students, so there are 112 students and we know that there is 1/8 of teachers, so there are 14 teachers.
Answer = 126.
Answer:
1256 inches
Step-by-step explanation:
The circumference of a circle is denoted by the formula: C = πd, where d is the diameter.
Here, the diameter is 400 inches, so plug that in:
C = πd
C = 3.14 * 400 = 1256
The answer is 1256 inches.
3 is the Coefficient in the following expression.
Answer:
-39x+21
Step-by-step explanation:
F: 6x
O: -3x
I: -42x
L: 21
6x-3x-42x+21= -39x+21
Answer:
If you are adding to fractions that are both greater than 1/2, the sum will be greater than 1.
Step-by-step explanation: 1/2 + 1/2 =1
Since both fractions are greater, obviously the sum will too.
Examples: 2/3+3/4= 1 5/12 4/6+6/9= 1 1/3
Hope this helps
