Eight less than four times a number is less than 56. What are the possible values of that number?

Damm [24]

For this case we can algebraically rewrite the expression given as:

$8-4x$

Where:

x: Represents the unknown number

Subtracting 8 from both sides of the inequality we have:

$-4x$

Dividing between 4 on both sides of the inequality:

$-x$

We multiply by -1 on both sides taking into account that the sense of inequality changes:

$x> -12$

ANswer:

$x> -12$

Greg invested $6000 in a bond with a yearly interest of 4%. His total interest on his investment was $1200. What was the length

kow [346]

Answer:

5 years

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

t = 1200 / ( 6000 × 0.04 ) = 5

t = 5 years

The time required to

accumulate simple interest of $ 1,200.00

from a principal of $ 6,000.00

at an interest rate of 4% per year

is 5 years.
