If 3x + 7y = 12 and x-y= 1, then what is the value of 5x + 5y?
lilavasa [31]

Answer:

14.

Step-by-step explanation:

3x + 7y = 12

x - y = 1           Multiply this by -3:

-3x + 3y = -3     Add this to equation 1:

0 + 10y = 9

so y = 9/10 = 0.9.

x - 0.9 = 1

x = 1.9.

So 5x + 5y = 5*1.9 + 5*0.9

= 14.

Ahman has a lawn care business. he charges $25 per lawn to mow the grass. if his monthly expenses are $100, how many lawns must
zmey [24]

Answer:

14

Step-by-step explanation:

you can write an equation to represent the situation:

let x represent the number of lawns he has to mow

then, the monthly profit would be 25x - 100.

in order to make $250, this equation has to be equal to 250:

25x-100=250

now, solve this:

add 100 to both sides

25x = 350

divide both sides by 25

x = 14

he must mow 14 lawns
