12.4%x = 7.13

Simplify both sides of the equation.

0.124x=7.13

Divide both sides by 0.124.

0.124x / 0.124 = 7.13 / 0.124

x=57.5

12.4% = 12.4/100 = 0.124

0.124n = 7.13

Divide each side by 0.124.

n = 7.13/0.124

n = 7130/124

n = 57.5

24 - 4 x 2 + 4b = 20 - 16​
AnnZ [28]

Answer:

b = -3

Step-by-step explanation:

Solve for b:

4 b - 4 2 + 24 = 20 - 16

-4×2 = -8:

4 b + -8 + 24 = 20 - 16

Grouping like terms, 4 b - 8 + 24 = 4 b + (24 - 8):

4 b + (24 - 8) = 20 - 16

24 - 8 = 16:

4 b + 16 = 20 - 16

20 - 16 = 4:

4 b + 16 = 4

Subtract 16 from both sides:

4 b + (16 - 16) = 4 - 16

16 - 16 = 0:

4 b = 4 - 16

4 - 16 = -12:

4 b = -12

Divide both sides of 4 b = -12 by 4:

(4 b)/4 = (-12)/4

4/4 = 1:

b = (-12)/4

The gcd of -12 and 4 is 4, so (-12)/4 = (4 (-3))/(4×1) = 4/4×-3 = -3:

Answer: b = -3

Rabiyas mother is tired so rabia decided iron her clothes but the ironing cloth herself but the ironing board is too high for he
xeze [42]

This is a guess, but, from what I've researched, maybe decrease? I've looked into it alot and that's just I think, though, it may depend on the previous height. Still, just an educated guess (I've got 100% on all kinds of quizzes because of educated guesses so, it may work!)
