What is the answer to this inequality? -1> -2(x-4)-5(4x-7)

Step-by-step explanation:

-1>-2(x-4)-5(4x-7)

Open brackets

-1 > -2x + 8 - 20x +35

-1 > -22x + 43

Collecting like terms

22x < 43 + 1

22x < 44

x < 44/22

x < 2

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
