How do you subtract 9-3 7/8?

2 answers:

7 0

Since 1-7/8=1/8, you have to also subtract 9-3=6. But since there is a fraction, you have to take away and extra one since if it was six it would be too big if you tried to add it back to 3&7/8. It would equal out to 10, so the answer is 5&1/8. If you add that up it equals 9.

You take 9 times 8 which is 72out of 9 and subtract 3 which is 7 and 7/8 out of 7 is 6 and 1/8

Answer:

$2.5\ m/s^2$

Step-by-step explanation:

Newton's Second Law: Force on a body is equal to the product of mass and acceleration of the centre of the mass of the body.

$Force(F)=Mass(m)\times Acceleration(a)$

Initially:

$Let\ mass=m\ kg\\\\acceleration=10\ m/s^2\\\\Force(F)=m\times 10=10m$

At the end of the road:

$Let\ mass=4\times m\ kg\\\\acceleration=a\ m/s^2\\\\Force(F)=4m\times a=4ma$

$Both\ forces\ are\ equal\\\\4ma=10m\\\\divide\ both\ the\ sides\ by\ m\\\\4a=10\\\\a=\frac{10}{4}\\\\a=2.5\ m/s^2$

luda_lava [24]

X = adults
Y = child

X+y=168
X=168-y

$10x + $7y = $1446

10(168-y) + 7y = 1446
1680 - 10y + 7y = 1446
-3 y = -234
Y = 78

X = 168-78
X = 90

$10*90 + $7*78 =
$900 + $546 = $1446
