6(2x-8)+3=15
12x-48+3=15 Distribute the 6
12x-45=15 Add (-48) and (3)
12x=60 Add 45 to both sides
x=5 Divide both sides by 12

Distribute.
6 times 2x= 12x
6 times 8= 48
12x+48+3=15
12x+51=15
subtract 51 from both sides.
12x=-36
divide by 12 on each side
-3=x

HELP!!

taurus [48]

Lets convert

1mile=5280ft
1h=3600s

$\\ \rm\longmapsto 1mph$

$\\ \rm\longmapsto \dfrac{5280}{3600}ft/s$

$\\ \rm\longmapsto 1.46ft/s$

If rounded

$\\ \rm\longmapsto 1.5ft/s$

Find the compound interest on ₹ 31,250 at 12% pa for 2 1/2 years

IRISSAK [1]

Answer:

42,183

Step-by-step explanation:

We will use the Continuous Compounding Interest since a regular interval was not stated.

P(t) = Pe^(rt)

We will plug in the variables to the formula

P(t) = 31250 * e^(.12 * 2.5)

We can simplify and evaluate the compound interest.

P(t) = 42183.08
