One yard company charges $10x + $50 a month to mow and edge a lawn. a second company charges $8x + $60 a month to mow and edge a lawn. each lawn company also offers additional services for an extra fee. let x represent the number of additional services. mr. mead is comparing the two companies. how many additional services are needed for the two companies to be the same price?

Are needed 5 additional services for the two companies to be the same price

Step-by-step explanation:

If the two companies charge the same price:

$10x + $50 = $8x + $60

$10x - $8x = $60 - $50

$2x = $10

x = $10/$2

x = 5

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
