Acompany invests 5 in a savings account that pays 3% interest per year. write a direct proportion equation that relates interests and years

I = 1500 t

Where, I = interest, t = time(in years)

Step-by-step explanation:

Here, the principal amount, P = 50000,

Annual rate of interest, r = 3 %

Let the total interest after t years is I,

So, by the simple interest formula,

Since, In the above equation,

The interest and time are directly proportional to each other,

Hence, the above equation is the direct proportion equation that relates interests and years.

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
