3x-5 does not belong

Reasoning :

Plug in “1” to each X unit

3(1) -5 = -2

1 + (1) = 2
(1)2 + 5(1) + 6 = 13

Nick and June win some money and share it in the ratio 4:5. Nick gets £40. How much did June get?
sineoko [7]

Answer:

June gets \£50

Step-by-step explanation:

Let

x ----> amount of money Nick gets

y ----> amount of money June gets

we know that

\frac{x}{y}=\frac{4}{5} -----> equation A

x=40 ----> equation B

solve the system by substitution

substitute equation B in equation A

\frac{40}{y}=\frac{4}{5}

solve for y

Multiply in cross

(40)(5)=y(4)\\y=200/4

y=\£50
