60 points (3 different questions) INEQUALITIES AND EQUALITY SOLVING -6(1+7x)+7(1+6x)=-2 (I got no solution but I want to make sure that's correct)

-2(2-2x)-4(x+5)≤ -24 (I think I got the answer but I have no clue how to do this on a number line)

-2(5+6n)<6(8-2n) (I think I got the answer but no clue on the number line)

I will mark the best answer but there is a 24-hour time limit!

1. No solution

2. All real numbers

3. Always true

Step-by-step explanation:

look at the picture and you will see the answer, for the numbers 3 -2(5+6n)<6(8-2n) it all real numbers are solutions.

Step-by-step explanation: hope this help

false

step-by-step explanation:

the meaning of changing is to edit or make something different.

but transmitting means cause (something) to pass on from one place or person to another.

there 2 different things

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
