178444.58 It is a matter of how you arrange your decimal place so while adding make sure the 3 in the second number is under the 2 in the first number.
answer is 7 pigs and 4 chicks
pigs' legs = 7 x 4 = 28
chicks' legs = 4 x 2 = 8
28 + 8 = 36 legs
-16 + 4(2g - 18) = 0
Distribute 4 inside the parentheses.
-16 + (8g - 72) = 0
Combine like terms (-16 - 72).
-88 + 8g = 0
Add 88 to both sides.
8g = 88
Divide both sides by 8.

The following table shows the total number of quizzes taken in high school. how many quizzes are taken per week?
The unknown number is n. So n is the unknown variable in the equation.
In order to write an equation in which n is included we must know some dependence of n with other values.
We know that <span>the difference of three times a number and 44 is −19. So, we can write:
3*n-44=-19
3*n=-19+44
3*n=25
n=25/3
