First one I just answerd, the answer is x=8.2 or 8 and 1/5

2nd one
divide both sides by 2 and distribute
21x+35-4x+24=131
17x+59=131
minus 131 both sdes
17x=72
divide both sides by 17
x=72/17





3.
add 14.8 to both sides
0.025x=22.25
divide both sides by 0.025
x=890




4.
divide oth sides by 2.5
2(3x-2)=2x+6
expand
6x-4=2x+6
minus 2x both sides
4x-4=6
add 4 both sides
4x=10
divide by 4
x=10/4=5/2

Is -2/9 greater or less then -4/9
Setler [38]
Greater than! With negative numbers, the number closer to 0 is always the greater value. The number farther away from 0 is the lesser value. When we compare fractions with the same denominator, we have to compare to numerator. -2 is greater than -4, therefore -2/9 is greater than -4/9.

If the square of twice a number is 81, what is the number? I tried doing 2x^2=81 but that did not come out to the answer 4.5,-4.
Vlada [557]
If the number is n then

square of 2 times a number
square of 2n
(2n)²
that was your mistake, because (2n)²=4n², not 2n²

the result is 81
(2n)²=81
square root both sides
remember positive and negative roots
2n=+/-9
divide by 2
n=+/-4.5

n=4.5 or -4.5
