Remark
All you need do is assume the small triangle is similar to the large one. MO:ML :: MP:MN must be solved.
Givens
MO = 28
ML = 28 + 14
MP = y
MN = y + 18
Equation
28:28+14 :: y: y + 18
Solve
28/42 = y / (y + 18)
28*(y + 18) = 42y Remove the brackets
28y + 18*28 = 42y
28y + 504 = 42y Subtract 28y from both sides.
504 = 42y - 28y
504 = 14y Divide by 14
504/14 = y
y = 36
This looks simple...for 14 the perimeter is x+3+x+3+2x-1+2x-1. Simplified is 6x+6-2. Which is 6x+4.
Thank me if it looks right!
For 15...2y+3+2y+3+x+3+x+3...Which is 4y+12+2x.
Answer:
9048 , 191, or 17
Step-by-step explanation:
72+8=80+16=96
So the quotient means the problem.(addition, subtracting etc)
Answer:
8 girls
Step-by-step explanation:
8 girls If there are 20 children and for every 3 boys there is 2 girls that's 5 children. 5x4 = 20 so in every 5 kids there is 2 girls. So then do 4x2 = 8
