Let the triangle be abc with equal sides ab,bc and ca
then perimeter = 3 ab = 12a + 18b
ab = = 4a + 6b ( each side will have this length)
Now since qr is a mid segment it will be = half length of ab
So qr = 2a + 3b Answer
Answer:
a. 80.25
b. 104
Step-by-step explanation:
For (a), you add all the numbers together and divide by 4 because there are 4 test scores.
87 + 92 + 63 + 79 ÷ 5 = 80.25
For (b), we need to set up an equation. It is going to be a similar concept.
87 + 92 + 63 + 79 + x ÷ 5 = 85
x = 104
Hope this helps!
