Kenya plans to make a down payment plus monthly payments in order to buy a motorcycle. At one dealer she would pay $2,350 down a
vovangra [49]

Answer:

After 16 months, Kenya will have paid $5,550

Step-by-step explanation:

This is a guess and check type of a problem.  You guess a number of months, plug it into x, and see if both equations come out with the same answer.

 If you plug 16 into the first dealer's equation, you get y= 200(16) + 2350.  Solving this equation will mean y equals 5550.

If you plug 16 into the second dealer's equation, you get y= 175(16) + 2750.

Solving this equation will mean y also equals 5550.

Write an absolute value inequality for each of the following. Then graph the
n200080 [17]

An absolute value inequality for "all numbers less than 7 and greater than -7" is given by |x| < 7.

<h3>How to write an absolute value inequality?</h3>

Based on the information provided, we can logically deduce that the statement describes an intersection of set because the word "and" was used.

This ultimately implies that, we would use the less than (<) symbol to write an absolute value inequality for the given statement:

|x| < 7

Therefore, this can be translated as follows:

-7 < x < 7      or      x < 7  and    x > -7.

insens350 [35]

Answer:

13.9%

Step-by-step explanation:

Given data

Expected weight = 230 pounds

Actual weight= 262 pounds

Required

The percent error

Error= Actaul- expected/ expected *100

Error= 262-230/230*100

Error=32/230*100

Error=0.139*100

Error=13.9%

Hence the error is 13.9%
