Question

I need help with #2 and 4 please help me T^T

Answer 1

Answer:

2. w = -90

4. b = 8

Step-by-step explanation:

Multiply both sides by the reciprocal of the number multiplying the variable.

2.

$-\dfrac{2}{3}w = 60$

$-\dfrac{3}{2} \times (-\dfrac{2}{3}w) = -\dfrac{3}{2} \times 60$

$w = -\dfrac{180}{2}$

$w = -90$

4.

$9.6 = 1.2b$

$\dfrac{1}{1.2} \times 9.6 = \dfrac{1}{1.2} \times 1.2b$

$8 = b$

$b = 8$
