Hello, who can help me with this question and if you can explain each letter to me, a, b, c, please, it would help me a lot. it says:
solve the following operations: a)-3×(4+(-5)×2= b)7×(5×(-2)]= c)4×{(-7)×[(-5)×{(-2)}=
​

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

6 and 24

step-by-step explanation:

6 x 4 = 24
