Answer:

-5(3x + 6) = -3(4x - 2)

Distribute -5 through the parenthesis

-15x - 30 = -3(4x - 2)

distribute -3 through the other parenthesis

-15x - 30 = -3( -12x + 6 )

move the variable the left hand side, change sign

-15x + 12 - 30 = 6

move constant to the right hand side

-15x + 12 = 6 + 30

collect like terms

-3x = 6 + 30

add the numbers

-3x = 36

divide both sides by -3

-3/-3 = 36/-3

x = -12

Answer:

-5(3x + 6) = -3(4x - 2)

-15x-30=-12x+6

-30-6=-12x+15x

3x=-36

x=-36/3=-12

a solution of trioxonitrate (v) acid contained 0.67g in 100cm³. 31cm³ of this solution neutralized 25cm³ of a sodium trioxocarbo
FinnZ [79.3K]

Answer:

0.67 / 100 : 31^3 : 31^3 / 25cm^3

x 10

0.67 / 100 = 67 / 10000000  grams/cm  :  29791 / 15625 / 29791    

149253.731  : 0.52

divide by 1000

= 149.253731

= 149.3 kg

Ratio kg = 149.3 : 0.5

Step-by-step explanation:

Mole Ratio

The mole ratio compares the number of moles in a balanced equation.

This is the comparison between the coefficients in front of the chemical formulas.

If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species.

Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product.

Mole Ratio Units

Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2 to 1 mole of H2 is 3:1 or 3 mol O2: 1 mol H2.

Is is right? If not, please correct me (:
Illusion [34]

Answer:

undefined

0

Step-by-step explanation:

The formula for slope is

m = (y2-y1)/ (x2-x1)

We have points

(-7,2) (-7,-7)

m = (-7-2) /(-7--7)

   = -9/(-7+7)

   = -9/0

This is undefined

We have points

(-8,-3) (6,-3)

m = (-3--3) /(6--8)

   = (-3+3/(6+8)

   = 0/14

How could you use the Commutative Property of Addition to rewrite the expression −21 + 7? A) −21(7) B) 3(−21) + 7 C) 7 + (−21) D
Ierofanga [76]

Answer:

C

Step-by-step explanation:

The commutative property of addition reorganizes parts of an equation without changing the answer. C includes the same numbers (-21, +7) without changing the answer (-14)
