Answer:
36
Step-by-step explanation:
9/10 multiplied by 40= 36 words
9 - 2c + c = -13
9 - 3c = -13
-3c = -22
c = 7 1/3
Answer:
Optioin 4
Step-by-step explanation:
12/8 = 15/(x-4)
12x - 48 = 120
12x = 168
x = 14
If there are two hydrogen atom molecules in one atom of water you'd do 51 times 2, getting you 102 hydrogen atoms in 51 water molecules.
Simplify both sides of the equation
-5/2 x +3/4 x = -3/4
Combine like terms
(-5/2 x + 3/4 x )
-7/4 x = -3/4
-7/4 x = -3/4
Multiply both sides by 4/(-7)
(4/-7)*(-7/4 x ) = (4/-7 ) * ( -3/4 )
x = 3/7
