Answer:

a), b), e)

Step-by-step explanation:

<em>a) -30(3 + 2w) = -90 - 60w</em>

<em>b) (-9 − 6w) x 10 = -90 - 60w</em>

c) -3(30 - 20w) = -90 + 60w

d) (6 + 4w) × 15 = 90 + 60w

<em>e) −20(4.5 + 3w) = -90 - 60w</em>

Consider this equation:
aleksandrvk [35]

Answer:

  • Plan: separate the variable term from the constant term; divide by the coefficient of the variable.
  • Steps: add 4 to both sides; collect terms; divide both sides by 3.

Step-by-step explanation:

The first step is to look a the equation to see where the variable is in relation to the equal sign, and whether there are any constants on that same side of the equal sign.

Here, the variable terms are on the left, and there is a constant there, as well. The plan for solving the equation is to eliminate the constant that is on the same side of the equation as the variable, then divide by the coefficient of the variable. To find that coefficient, we need to collect terms. In summary, the plan is to ...

  • add 4 to both sides of the equation
  • collect terms
  • divide by the coefficient of the variable (3)

Executing that plan, the steps are ...

  -2x -4 +5x +4 = 8 +4 . . . . add 4

  3x = 12 . . . . . . . . . . . . . . . collect terms

  x = 4 . . . . . . . . . divide by 3

N two years, Linda will be half as old as her mother. Her mother is 38 years old now.
Ksenya-84 [330]
I'm not sure about the formula.
But since 38/2=19
19-2=17
Linda is 17 years old.
a possible formula could be:
L=38/2-2
