Which value of x is a solution of 8&gt; (x-6)-2
Vitek1552 [10]

Answer:

The answer is x < 16.

Step-by-step explanation:

1) Remove parentheses.

8 > x - 6 - 2

2) Simplify x - 6 - 2 to x - 8.

8 > x - 8

3) Add 8 to both sides.

8 + 8 > x

4) Simplify 8 + 8 to 16.

16 > x

4) Switch sides.

x < 16

<em><u>Therefor</u></em><em><u>,</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>></u></em><em><u> </u></em><em><u>16</u></em>.

Herodoto, historiador
Masja [62]

Answer:

Defining the straight number of integers, we have to live in the year 2020 and this Greek historian was born in the year - 484.

Step-by-step explanation:

When using whole numbers, we denote positive numbers as the number of numbers after 0, and negative numbers the number of numbers before zero.

So if we consider the birth of Christ to be the year 0, then all years before Christ will be negative and all years after Christ will be positive.

So we have to live in the year 2020 and this Greek historian was born in the year - 484.

Two boys' ages total 24. Four less than six times the younger boy's age equals five more than three times the older boy's age. W
babunello [35]

Hey there!

Let x be boy 1's age, and y be boy 2's age (younger).

Firstly, we know that x+y=24

6y-4=3x+5 <== we have this right here. (using the rules given by the question)

We can use all the equations to help find the answer.

x+y=24

x+y (-y)= 24(-y)

x=24-y

Plug that into x in the equation we made above.

6y-4= 3(24-y)+5

6y-4= 72-3y+5

Add 4 to each side.

6y= 81 -3y

9y=81

y=9

We know the younger boys age is 9.

We can plug that in to find the older one's age.

x+9= 24

x= 15

The boy's ages are 9 and 15.

I hope this helps!
