A plane has two kinds of packages to deliver; each of the first kind weighs 140 pounds and occupies 3 cubic feet of space. Each of the second kind weighs 190 pounds and occupies 7 cubic feet of space. The plane is limited to a total of 5500 pounds of cargo and has 270 cubic feet of cargo space available. Write the inequalities that describe the number of each kind of package that can be carried. (Let the x refer to the number of the first kind of package and the y refer to the number of the second kind of package.)

Step-by-step explanation:

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
