Burka [1]

Answer:

75 - 35y / 3 + 2y = -4

( 75 - 35y + 6y ) / 3 = -4 [ Taking LCM ]

( 75 - 29y ) / 3 = -4

75 - 29y = -12

29y = 75+12

29y = 87

y = 3

Alika [10]

Answer:

- 3(x - 1) =  - 1(5 - x) \\  \\ 3 - x + 1 =  - 5 + x \\  \\  - x - x =  - 5 - 3 - 1 \\  \\  - 2x =  - 5 - 3 - 1 \\  \\  - 2x =   - 9 \\  \\ x =  \frac{ - 9}{ - 2}  \\  \\ x = 4.5

(2 x 106) x (0.00009) = ?
RSB [31]

I think you meant to write

(2 × 10⁶) × 0.00009

First, convert 0.00009 to scientific notation:

0.00009 = 9 × 10 ⁻⁵

Then

(2 × 10⁶) × 0.00009 = (2 × 10⁶) × (9 × 10 ⁻⁵)

… = (2 × 9) × (10⁶ × 10 ⁻⁵)

… = 18 × 10¹

… = 1.8 × 10²
