Answer:
C = (1, -1)
Step-by-step explanation:
For that 3:1 division, the calculated value of point B is ...
B = (3C +1A)/(3+1)
Solving for the value of C, we find ...
4B = 3C + A . . . . multiply by 4
4B -A = 3C . . . . . subtract A; next divide by 3.
C = (4B -A)/3 = ((4(-1)-(-7))/3, (4(0)+-3)/3) . . . . substitute given values
C = (3/3, -3/3) . . . . simplify a bit
C = (1, -1)
Answer:
w = -12
Step-by-step explanation:
w/6 + 5/8 = -1 3/8
Subtract 5/8 from each side
w/6 + 5/8-5/8 = -1 3/8 - 5/8
w/6 = -1 3/5 - 5/8
w/6 = -1 8/8
w/6 = -2
Multiply by 6 on each side
w/6 *6 = -2*6
w = -12
Answer:
12 students
Step-by-step explanation:
First, find the percentage of how many students have siblings:
3/10 = 0.3 = 30%
40 * 0.3 = 12
This means that 30% of this class are 12 students. These 12 students have siblings.
Hope this helps!
