3. Caleb has $25 to spend on prizes for a game at the school fair. Lip balm costs $1.25 each, and mini-notebooks cost $2.50 each

Snowcat [4.5K]

Answer:

linear equation in Standard form that can be used to determine how many of each prize Caleb can buy is $1.25x+ 2.50y = 25$

Step-by-step explanation:

Given:

Total cost spent on prizes for games = $25

Cost of one lip balm = $1.25

Cost of one mini notebook = $2.50

A) linear equation in STANDARD FORM that can be used to determine how many of each prize she can buy.

Let the number of lip balms be x and the number of mini note books be y. Then

$1.25x+ 2.50y = 25$

B. Graph the equation using x- and y- intercepts.

Now by trial and error method

$1.25(0)+ 2.50(10) = 25$

$1.25(2)+ 2.50(9) = 25$

$1.25(4)+ 2.50(8) = 25$

$1.25(6)+ 2.50(7) = 25$

$1.25(8)+ 2.50(6) = 25$

$1.25(10)+ 2.50(5) = 25$

$1.25(12)+ 2.50(4) = 25$

$1.25(14)+ 2.50(3) = 25$

$1.25(16)+ 2.50(2) = 25$

$1.25(18)+ 2.50(1) = 25$

$1.25(20)+ 2.50(0) = 25$

Thus Caleb can buy 0,2,4,6,8,9,10,12,14,1,6,18,20 lip balms and

0,1,2,3,4,5,6,7,8,9,10 mini note books respectively

Now plotting these value in the graph, we get the below graph

Three cars are driving on a racetrack. The mean speed of the three cars is 100 miles per hour. Car X drives 101 miles per hour a

evablogger [386]

Answer:

Less than 100. Z=83

Step-by-step explanation:

The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 101, 116, and Z or unknown. The mean of them is 100. Solve for Z.

100 =(101+116+Z)/3

300=217+Z

83=Z
