Answer:
(c) 162 cm
Step-by-step explanation:
The centroid divides a median into parts with the ratio 1:2, so RL:LD = 1:2. Then RL:RD = 1:(1+2), and RD = 3RL.
RD = 3·54 cm
RD = 162 cm
Answer:
10 more than the product of 3 and x
= 3x + 10
9 less than the quotient of n and 5
= n/5 - 9 (n divided by 5 minus nine)
8 times the product of 5 and t
= 8 x 5t
3 times the sum of x and 5
= 3 x (x + 5)

= 6 + 7.5n
Answer:
15 people are able to be at the charity gala because 77:55 divided by 5:17.
Y = base pay + (variable pay * x)
37.50 = base pay + (variable pay * 5)
75 = base pay + (variable pay * 20)
let v be the variable pay:
base pay = y - variable pay * x
37.50 - 5v = 75 - 20v
-5v + 20v = 75 - 37.50
15v = 37.50
v = 37.50/15
v = 2.5
37.50 - 5(2.5) = 75 - 20(2.5)
37.50 - 12.50 = 75 - 50
25 = 25
base pay is 25 ; variable pay is 2.50 per newspaper delivered.
y = 25 + 2.50x
Y = 5/3 - 4 , y-intercept is 4 , slope is 5/3
