Jose is mailing packages. Each small package cost him $2.90 to send

=$15.10

Step-by-step explanation:

Let s= the cost of a small package and

l= the cost of a large package

4 small packages and 1 large package

4s+l

Substitute

s=$2.70 and l=$4.30

=4($2.70)+($4.30)

=$15.10

10 you would take 50/ .2

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
