For which values of x is the inequality 3(1 + x) &gt; x + 17 true?
mrs_skeptik [129]

Answer:

x>7

Step-by-step explanation:

3(1 + x) > x + 17

distribute

3 + 3x> x+17

subtract x from each side

3 +3x-x > x-x+17

3+2x > 17

subtract 3 from each side

3-3+2x > 17-3

2x>14

divide by 2

2x/2 > 14/2

x>7

The simple interest earned on a deposit of 4000 at 5% for 120 days
Ymorist [56]

Answer:A = $4,066.00

Step-by-step explanation:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year.

Putting time into years for simplicity,

120 days / 360 days/year = 0.33 years.

Solving our equation:

A = 4000(1 + (0.05 × 0.33)) = 4066

A = $4,066.00

The total amount accrued, principal plus interest, from simple interest on a principal of $4,000.00 at a rate of 5% per year for 0.33 years (120 days) is $4,066.00.

* Hopefully this helps:) Mark me the brainlliest:)!!
