1. You can add 7 units to both sides of the scale so it becomes a balance between x on the left and 21 on the right.
x ___ 21
1A) The only number from the set that will keep the balance is x ∈ {21}
1B) The number on the right (21) will be more than x for x ∈ {0, 1, 7, 14}
1C) The number on the right (21) will be less than x for x ∈ {28, 30}
2A) (x +x +x) +(2 +4) = 102
3x +6 = 102 . . . . . . . . simplified equation
2B) Solving the equation, you have
3x = 102 -6
x = 96/3 = 32
The number that could be a value of x is 32.
<span>Which one is closer to 41/50, 9/11 or 10/11
=> Let’s find the value of the two given choices to be able to fin which one
is closer to 41/50
=> 9/11 convert this to decimal number
=> 9 divide by 11
=> 0.82
=> 10/11 convert in decimals
=> 10 divide by 11
=> 0.91
Now, we have the value of both numbers, let’s find the value of 41/50
=> 41/50
=> 41 divided by 50
=> 0.82
Thus, the closer number to 41/50 is the 9/11 because they both have 0.82
decimal value.

The answer is: " (x − 8) (x + 3) " .
__________________________________________________________
" (x − 8) (x + 3) " are the factors of: " x² − 5x − 24 " .
_________________________________________________________
Explanation:
__________________________________________________________
Given: "x² − 5x − 24 " ; Factor this "trinomial" expression completely.
We notice the "-5x" and the "-24 .
What factors of "-24" add up to "-5" ?
-1 + 24 ? No.
-24 + 1 ? no.
-12 + 2 = -10? No.
12 + (-2) = 12 - 2 = 10 ? No.
-3 + 8 = 5 ? No.
-8 + 3 = -5 ? Yes!
So: " (x − 8) (x + 3) " are the factors of: " x² − 5x <span>− 24 " .
