Answer:
f = 1
Step-by-step explanation:
Use the method of cross- multiplication
= 
⇒ ad = bc, thus
20f = 5(f + 3) ← distribute
20f = 5f + 15 ( subtract 5f from both sides )
15f = 15 ( divide both sides by 15 )
f = 1
Answer:
the ansewre is reppetition bc it is right
Step-by-step explanation:
Seun : Tayo : Dayo
4 : 3 : 2
Total parts = 4 + 3 + 2 = 9
9 parts = N120
1 part = N120 ÷ 9 = N12.33
Seun = 4 parts = N12.33 x 4 = N53.33
Dayo = 2 parts = N12.33 x 2 = N26.67
N53.33 + 26.67 = N80
Answer: N80
1) in first place you must Know F(X) for every value of x
F(0) = 250(0.5)^0 = 250
f(1) = 250(0,5)^1 = 250*0,5 = 125
f(2)= 250(0,5)^2= 250*0,25 = 62,5
the average is = 250+125+62,5/ 3 = 145,83
Step-by-step explanation:
phukan = x
Nanwan = y
let this be a simultaneous equation.
x - y = 18.... equation i
x + y = 100.... equation ii
subtract equation i from equation ii
= 2y = 118
y = 59
substitute y = 59 in equation ii to get x
x + 59 = 100
x = 100- 59
x = 41
Nanwan = 59, Phukan = 41
