In the question , it is given that , a college student borrows $1,000 for 9 months to pay for a semester of school.

And the interest is $61.88 .

Let the monthly payment be $x . So in 9 months, the student paid $9x .

And interest is the difference of 9x and the money borrowed, that is

9x - 1000 = 61.88

Adding 1000 to both sides

9x = 1061.88

x = \frac{1061.88}{9} =$117.99

An algebraic expression of the form a + bx has the value of 15 when x = 2 and the value of 3 when x = 5. Calculate a + b.
Ainat [17]

Answer:

The value of the expression  (a +b)  = 19

Step-by-step explanation:

The given expression is a + bx.

Case - I   when x = 2, (a + bx) = 15

Putting the value of x , we get:  a + 2b = 15

or, a = 15 - 2b       ......  (1)

CAse II-  when x = 5, (a + bx) = 3

Putting the value of x, we get a + 5b = 3

or a = 3 - 5b   ....... (2)

Comparing (1) and (2)

15 - 2b = 3 - 5b

or, 5b - 2b = 3 - 15

or, 3b = - 12   ⇒ b  = -4

if b = -4, then a = 3 - 5b = 3 + 20  = 23

Hence, a = 23, b= -4

So, the value of (a +b) = 23 - 4 = 19

What is the converse of the linear pairs theorem
guapka [62]
<span>If you know the Linear pair Theorem, the converse can be easily obtained by switching the condition and the conclusion. For example, If it is raining, then the outside is wet. Converse: If the outside is wet, then it is raining. (It is not always true.)</span>
