If the mean of A and B is 20, the mean of B and C is 24 and the mean of A,B and C is 18.What is the mean of A and C?

Zielflug [23.3K]

Answer:

the mean of A and C is 10

Step-by-step explanation:

Given;

mean of A and B = 20

mean of B and C = 24

mean of A, B and C = 18

$\frac{A + B}{2} = 20\\\\A+ B = 40 ---- (1)\\\\\frac{B + C}{2} = 24\\\\B+ C = 48----(2)\\\\\frac{A+ B+ C}{3} = 18\\\\A+ B+ C= 54---(3)\\\\From (1); \ A = 40 - B\\\\From(2); \ C = 48 - B\\\\\Substitute \ the \ values \ of \ A \ and \ C \ into \ (3)\\\\(40-B) + B + (48-B) = 54\\\\simplify;\\\\(40 + 48) + (B-B-B)= 54\\\\88 -B = 54\\\\-B = 54-88\\\\-B = -34\\\\B = 34$

Recall; A = 40 - B

A = 40 - 34

A = 6

Also, C = 48 - B

C = 48 - 34

C = 14

Therefore, the mean of A and C is calculated as;

$= \frac{A + C}{2} \\\\= \frac{6 + 14}{2} \\\\= 10$

Please help fast! AB=?

maria [59]

∠A = 180° - (63°+101°)=16°

sine's rule

$\tt \dfrac{AB}{sin~C}=\dfrac{BC}{sin~A}\\\\\dfrac{AB}{sin~63}=\dfrac{9}{sin~16}\\\\AB=29.09$

Find the solution of this system of two linear equations using substitution 11x+3y=103 and y =3x+1

Lesechka [4]

11x+3y=103 and y=3x+1.

11x+3(3x+1)=103 -----> plug in (3x+1) for y in the first equation. You will want to distribute the 3 to the 3x+1 to get something that looks like:

11x+9x+3=103 ------> now you want to combine like terms

20x+3=103 ---> subtract 3 from both sides
20x=100 ----> divide both sides by 20
x=5

y=3(5)+1 ---> I like to plug in this to the equation that already has y isolated. 3*5 is 15, add 1 and you find that y=16.

(5, 16) will be your final answer (:
