They subtracted 1/3 from both sides instead of dividing 1/3 from both sides
pashok25 [27]3 years ago

Answer:

x= 15

Step-by-step explanation:

Francisca's mistake was that when she had an equation 5 = \frac{1}{3} x instead of dividing both sides by  \frac{1}{3}  she substracted  \frac{1}{3}  from both sides. So the correct way would be...

5 = \frac{1}{3} x\\\\(5)(3) = (\frac{1}{3} x )(3)

15 = x

PLEASE HELP!!!
soldi70 [24.7K]

Answer:

See below

Step-by-step explanation:

4(x + 5) = 9x + 4x − 34

4x + 20 = 9x + 4x − 34   [Distributive]

4x + 20 =  13x − 34         {Combine Like Terms]

4x - 13x + 20 = 13x - 13x − 34  [Subtractive:  -13x both sides]

-5x + 20 = - 34            [Combine Like Terms]

-5x + 20 - 20 = -34 - 20     [Subtractive:  - 20 both sides]

-5x  = -54               [Combine Like Terms]

x = -54/-5             [Division Property:  divide both sides by -5]

x =  - 10 4/5

1. -4x + 5 = 2x - 7<br> 2. 6x - 8 = 4x + 2<br> 3. -3x - 5 = 2x + 10
Svetllana [295]

Answer: 1. x=2

 2. x=5    

 3.x=-3

Isolate the variable by dividing each side by factors that don't contain the variable.

Move all terms not containing x    to the right side of the equation.

Hope this helped

Evaluate rs + 14s when r = 6 and s = 8
Ivahew [28]

Answer:

160

Step-by-step explanation:

Plug in 6 for r, and 8 for s in the expression:

(r)(s) + (14)(s) = (6)(8) + (14)(8)

Remember to follow PEMDAS. First, multiply, then add:

(6 * 8) + (14 * 8)

48 + 112

112 + 48 = 160

160 is your answer.
