$1.\\\dfrac{9}{2}(8-x)+36=102-\dfrac{5}{2}(3x+24)\ \ \ \ |\text{multiply both sides by 2}\\\\\not2^1\cdot\dfrac{9}{\not2_1}(8-x)+2\cdot36=2\cdot102-\not2^2\cdot\dfrac{5}{\not2_1}(3x+24)\\\\9(8-x)+72=204-5(3x+24)\ \ \ \ |\text{use distributive property}\\\\(9)(8)+(9)(-x)+72=204+(-5)(3x)+(-5)(24)\\\\72-9x+72=204-15x-120\ \ \ \ |\text{use commutative and associative property}\\\\-9x+(72+72)=-15x+(204-120)\\\\-9x+144=-15x+84\ \ \ \ |\text{subtract 144 from both sides}$

$-9x=-15x-60\ \ \ \ |\text{add 15x to both sides}\\\\6x=-60\ \ \ \ |\text{divide both sides by 6}\\\\\boxed{x=-10}$

$2.\\-12x-0.4 > 0.2(36.5x+80)-55\ \ \ \ |\text{use distributive property}\\\\-12x-0.4 > (0.2)(36.5x)+(0.2)(80)-55\\\\-12x-0.4 > 7.3x+16-55\ \ \ \ |\text{use associative property}\\\\-12x-0.4 > 7.3x+(16-55)\\\\-12x-0.4 > 7.3x-39\ \ \ \ |\text{add 0.4 to both sides}\\\\-12x > 7.3x-38.6\ \ \ \ |\text{subtract 7.3x from both sides}\\\\-19.3x > -38.6\ \ \ \ \ |\text{change the signs}\\\\19.3x < 38.6\ \ \ \ |\text{divide both sides by 19.3}\\\\\boxed{x < 2}$

Don't know if there was supposed to be another option but, it would be distribute over (x - 8).

A boat goes 3/4 hours with a speed of 8 mph and 1/3 hours with a speed of 12 mph. What distance did the boat cover in all this t

Reika [66]

Answer:

10 miles

Step-by-step explanation:

Given: Boat goes $\frac{3}{4}$ hours with 8 mph (i)

Boat goes $\frac{1}{3}$ hours with 12 mph (ii)

Now, lets find out distance separately to get total distance.

Formula for finding distance is

D= $Speed\times time$

D= $\frac{3}{4} \times 8$ (i)

D= $3\times 2$

∴ D1= 6 miles (i)

D= $\frac{1}{3}\times 12$ (ii)

∴D2= 4 miles (ii)

To find total distance, we will add d1 and d2

Total distance = $d1 + d2$

∴ Total distance = $6 + 4$

= 10 miles is the total distance covered by boat in all this time.

Answer:C

Step-by-step explanation:

I would say D or C but d is the identity property. And C is the distributive property.
