4.5% of 12000= 510
510x20= 10200
10200+12000
Answer:
$360
Step-by-step explanation:
The intial ratio of the sum shared between Khairul, Michael and Ethan is 6 : 4 : 5.
This would be 6x : 4x : 5x
Khairul gives $30 to Michael and $15.
The ratio is. Now;
(6x - 45) : (4x + 30) : (5x + 15)
We are told this is equal to the ratio 7:6:7
Thus;
((6x - 45) + (4x + 30))/(5x + 15) = (7 + 6)/7
(10x - 15)/(5x + 15) = 13/7
Factorize the left hand side;
5(2x - 3)/5(x + 3) = 13/7
5 will cancel out to get;
(2x - 3)/(x + 3) = 13/7
Cross multiply to get;
7(2x - 3) = 13(x + 3)
14x - 21 = 13x + 39
14x - 13x = 39 + 21
x = 60
Amount Khairul had initially was denoted as 6x.
Thus,6x = 5 × 60 = $360
Y - y₁ = m(x - x₁) slope(m) = 3 point (1, 4)
y - 4 = 3(x - 1)
y - 4 = 3x - 3
y = 3x - 3 + 4
3x - y = -1 <<< your answer
hope this helps, God bless!
Answer:
The solutions to the system of equations are:
Step-by-step explanation:
Given the system of the equations
Isolate x for for 4x-3y=-13
Divide both sides by 4
substitute y=5
The solutions to the system of equations are:
C 1:3
15:45 can be simplified by dividing by 15 to give you a ratio of 1minute if commercials for every 3 minutes of the actual show
