1. clark has 5 times as many pennies as dimes. If he has a total of 4.29, which two linear equations best model this system? a) P=3D and 0.01P+0.10D=4.29

b) P=3D and 1.10P+0.01D=4.29

c) P+D=3 and 0.01P+0.10D=4.29

d) D=5P and P+D=4.29

2. using the equation from question 1, how many coins does clark have in total?

.5 lb

step-by-step explanation:

12 in / 6 in =2 in

.25 x 2 = .5 lb

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
