Answer:

-10 -2d+7=8-10-3d

-2d + 7 =8 -3d

-2d + 7 =3d = 8

-2d + 3d = 8-7

d=8-7

d=1

Answer:

$d = 1$

Step-by-step explanation:

Step 1: Combine like terms

$d - 10 - 2d + 7 = 8 + d - 10 - 3d$

$(d - 2d) + (-10 + 7) = (8 - 10) + (d - 3d)$

$(-d) + (-3) = (-2) + (-2d)$

Step 2: Add 2d to both sides

$-d + 2d - 3 = -2 - 2d + 2d$

$d - 3 = -2$

Step 3: Add 3 to both sides

$d - 3 + 3 = -2 + 3$

$d = 1$

Answer: $d = 1$

A train travels a distance of 60 km at uniform speed. If the speed of the train was reduced by 10 kmh-1, the time taken to trave

tester [92]

Answer:

Initial speed is 32 m/s

At uniform speed, acceleration is 0, (a = 0).

When speed reduced, (v - u) = 2.78 ms-¹, t = 1800 sec, s = 60 ,000 metres.

From first equation of motion:

${ \boxed{ \bf{v = u + at}}} \\ { \tt{(v - u) = at}}$

substitute:

${ \tt{2.78 = (a \times 1800)}} \\ { \tt{acceleration = 0.0015 \: {ms}^{ - 2} }}$

from second equation of motion:

${ \boxed{ \bf{s = ut + \frac{1}{2} a {t}^{2} }}}$

substitute:

${ \tt{60000 = 1800u + ( \frac{1}{2} \times 0.0015 \times {1800}^{2}) }} \\ { \tt{1800u = 57570}} \\ { \tt{u = 32 \: m {s}^{ - 1} }}$

What is the density of an object haveing a mass of 5.0g and a volume of 45.0 cm3

JulijaS [17]

Using the formula d=m/v, we first need to convert 5.0 and 45.0 to their SI unit equivilents. 5.0g is 0.005kg, 45.0cm^3 becomes 0.000045m^3.Therefore, the density of your cube is 0.005/0.000045=111.11 kg/m^3(5 s.f)
