1. 12=x+3 12-3=9 now try 9+3 that is 12 so x=9
2. b+0.6=-1 -1-0.6=-1.6 -1.6+0.6=-1 b=-1.6
3. a=-9
4. x=-39 I believe
5. a=-4.3

Which is the best estimate of the product of the fractions? StartFraction 4 Over 7 EndFraction times StartFraction 8 Over 9 EndF

Lapatulllka [165]

Answer:

Product = $\dfrac{64}{135}$

Step-by-step explanation:

The expression is as follows :

$\dfrac{4}{7}\times \dfrac{8}{9}\times \dfrac{14}{15}$

We need to find the product of the above expression

As 7 × 2 = 14

So, it will become :

$4\times \dfrac{8}{9}\times \dfrac{2}{15}\\\\=\dfrac{4\times 8\times 2}{9\times 15}\\\\=\dfrac{64}{135}$

So, the product of the given fractions is $\dfrac{64}{135}$ .

A rectangular flower bed is five feet longer than it is wide. its area is eighty-four square feet.

777dan777 [17]

Lets say w is the width of the flower bed. We can make an equation to find the area.
The length of the of the flower bed is (w+5) and the width is w.
To find the area we need to multiply the length(w+5) by the width(w) and set it equal to 84,
(w+5)(w)=84
w^2 +5w=84
Using the quadratic equation you get the solutions of 7 and -12. Since 7 is positive it is our width. Our length is 7+5 or 12.
