$\frac{3.2}{0.8} = \frac{32}{8} = \frac{4\times 8}{8} = 4$

9w-4w+6<1+5w supposed to combine like terms

Mariana [72]

Answer/Step-by-step explanation:

Given:

$9w - 4w + 6$ < $1 + 5w$

To solve, collect like terms.

Subtract 5w from both sides

$9w - 4w + 6 - 5w$ < $1 + 5w - 5w$

$9w - 4w - 5w + 6$ < $1$

$6$ < $1$ (incorrect)

The inequality given has no solution or an information is missing.

A rectangular pool has dimensions of 40 ft. and 60 ft. The pool has a patio area around it that is the same width on all sides.I

ladessa [460]

Area of pool edge = Area of big rectangle - Area of the pool

Area of pool edge = Area of the pool = 40 × 60 = 2400 ft²

2400 = Area of big rectangle - 2400
Area of big rectangle = 2400 + 2400
Area of big rectangle = 4800

Length × width = 4800

From the diagram, we need the length to be [x + x] more than the length of the pool, where x is the distance from the pool edge to the patio edge.

We also need the width of the big rectangle to be [[x + x] more than the width of the pool.

Length = 60 + 2x
Width = 40 + 2x

Length × Width = [60+2x] × [40+2x]
4800 = 2400 + 120x + 80x + 4x²
0 = 4x² + 200x - 2400
0 = 4[x² + 50x - 600]
0 = x² + 50x - 600
0 = [x - 60] [x + 10]

x - 60 = 0 OR x + 10 = 0
x = 60 OR x = -10

We can only use the positive value of x since the context is length

Hence, x = 60
