-5x + 5y = 40 -20x +20y =160 -5x + 5(8) = 40
4x + 3y = 24 20x +15y =120 -5x + 40 = 40
35y = 280 -5x =0
y = 8 x = 0

is the arithmetic mean of the x-coordinates of the endpoints of the segment
. Similarly, the y-coordinate of the midpoint M of the segment
is the arithmetic mean of the y-coordinates of the endpoints of the segment
.
Answer:
11.05$
Step-by-step explanation:
Given the wholesale price of pillow is $6.50
Price in department store is 70% more than whole sale =1.7 times the wholesale

Answer:
Option A
Step-by-step explanation:
A = 3 +3 +3+3 = 12
B = 3⁴ = 81
C = 3² × 3² = 9 × 9 = 81
D = 3× 3 × 3 × 3 = 81
Answer:
B= 44.9506°
Step-by-step explanation:
WE apply sine angle formula

Given angle C = 51, c= 11 and b = 10

Plug in the values

Cross multiply it
10 * sin(51) = 11* sin(B)
7.771459615 = 11 sin(B)
Now divide by 11 on both sides
0.706496328 = sin(B)
Now 
B= 44.9506°
