Olve for x. Check each step or answer that is correct. 34(x + 4) = 14(x + 8) (A) Distribute 34 on the left side of the equation.

Fantom [35]

Answer:

x = -1.2

Step-by-step explanation:

Th given equation is :

34(x + 4) = 14(x + 8)

Step (A) Distribute 34 on the left side of the equation such as :

34x + 34(4) = 14(x + 8)

34x + 136 = 14(x + 8)

Step (B) Distribute 14 on the right side of the equation such as :

34x + 136 = 14x + 14(8)

34x + 136 = 14x + 112

Step (C) Subtract 14x from each side of the equation.

34x + 136 - 14x = 14x + 112 -14x

20x + 136 = 112

Step (D) Subtract 136 from each side of the equation.

20x + 136 -136 = 112 -136

20x = -24

Step (E) Divide both side by 20

$\dfrac{20x}{20}=\dfrac{-24}{20}\\\\x=-1.2$

So, the value of x is (-1.2). Hence, steps (D) and (E) are incorrect.

If P = 2l + 2w, the formula to find w is . If P is 30 units and l is 10 units, w is units.

Helen [10]

Answer:

If P is 30 units and l is 10 units, w is 5 units

Step-by-step explanation:

1. Let's check the information given to resolve the question:

P = 2l + 2w

If P is 30 units and l is 10 units, w is units

2. Replacing with the values:

P = 2l + 2w

30 = 2 (10) + 2w

30 = 20 + 2w

-2w = 20 -30 (Subtracting 2w and - 30 to both sides)

-2w = - 10

2w = 10 (Multiplying by - 1 at both sides)

w = 5 (Dividing by 2 at both sides)

If P is 30 units and l is 10 units, w is 5 units
