IF you are solving for d:
isolate the D, do the opposite of PEMDAS.
-d/6 + 12 = -7
(subtract 12 from both sides)
-d/6 + 12 (-12) = -7 (-12)
-d/6 = -19
(multiply 6 to both sides)
-d/6(6) = -19(6)
-d = -19(6)
-d = -144
-d/-1 = -144/-1
d = 144

Answer:
12 girls.
Step-by-step explanation:
24 ÷ 2 = 12
(This is divided to find out 1 part of the whole class as ⅓)
⅓ = 12
1 (whole) take away ⅔ = ⅓
Since ⅔ + ⅓ = 1
⅓ = fraction of girls in class
1 part = 12
So ⅓ = 12 girls out of 36 total students
Hope this helps. :)
This is what I did for factoring. Let me know if you need more work?
Answer:
x = 6
Step-by-step explanation:
44 + 3x = 5x + 2x + 20 transfer like terms to the same side of the equation with the opposite sign:
44 - 20 = 5x + 2x - 3x add/subtract like terms
24 = 4x divide both side by 4
6 = x
