−2(13x−15)
distribute by multiplication -2 to 13x and -15
-26x+30
Given that in a trianlgle the sides AB, BC, CA are in the ratio 3:4:6.
Let AB = 3k, BC = 4k and CA = 6k.
Then perimeter =3k+4k+6k = 13k
M, N, K are mid points of the sides.
By mid point theorem MN = 3k/2, NK = 4k/2 and KM = 6k/2
Hence perimeter of MNK = 13k/2 =5.2 (given)
Solve for k
k=2(5.2)/13 = 0.8
Hence sides are
AB = 3k = 3(0.8) = 2.4 in
BC = 4k= 3.2 in
CA = 4.8 in
Answer:
The distance from Endnville to Concord = 14.8 miles
Step-by-step explanation:
∵ Westfalls is 7 miles South of Endnville
∵ Concord is 13 miles West of Westfalls
∵ South and West are ⊥
∴ The distance from Endnville to Concord = √(7)² + (13)²
= 14.8 miles
Answer:
You can find the mean, by adding all the terms in each data set and dividing by the number of terms. For example, if there were four data points, you would add them all up and divide by four.
hope this helps!
