When money is invested at 4.5% simple interest for 4 months, the interest is $75. Find the principal

$555.6

Step-by-step explanation:

Simple interest = Principal x Rate x Time

Principal = Interest/Rate x Time

From the question, interest = $75

Rate= 4.5%; 4.5/100= 0.045

Time= 4 months

Slot the values into the formula:

P= 75/0.045 × 4/12

= 75/0.135

P= $555.6

you should at least use a calculater

step-by-step explanation:

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
