16) Adam and Lea are selling wrapping paper for a school fundraiser Customers can buy rolls of
plain wrapping paper and rolls of holiday wrapping paper. A dam sold 8 rolls of plain wrapping
paper and 7 rolls of holiday wrapping paper for a total of $145. Lea sold 4 rolls of plain
wrapping paper and 2 rolls of holiday wrapping paper for a total of $50 What is the cost each of
one roll of plain wrapping paper and one roll of holiday wrapping paper ?
O roll of plain wrapping paper: $7roll of holiday wrapping paper: $10
roll of plain wrapping paper. 58, roll of holiday wrapping paper: $9
O roll of plain wrapping paper: $15, roll of holiday wrapping paper. 35
roll of plain wrapping paper: S5, roll of holiday wrapping paper. $15

something over 10 so ? /10

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
