Step-by-step explanation:

We are told that you have two loans, for 2 years each. The total interest for the two loans is $138. On the first loan, you pay 7.5% simple interest on a principal of $800.

Let us find the amount of interest for 1st loan.

, where,

I = Amount of interest,

P = Principal amount,

r = Interest rate in decimal form,

t = Time

Let us convert our given rate for 1st loan in decimal form

Now let us find the amount interest for 2nd loan.

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
