Answer: A. t - 2d = -240 t - d = 320

Step-by-step explanation:

Let t be the price of a lawn mower at Turf Cutters and d be the price of the  same lawn mower at Lawn Masters.

As per given , we have

The price, t, of a lawn mower at Turf Cutters is $240 less than twice the price, d, of the same lawn mower at Lawn Masters.

2d-240=t\\\\\Rightarrow\ t-2d=-240 ...(i)

The difference in price between the mower at Turf Cutters and Lawn Masters is $320.

t-d=320 ...(ii)

So, the system of equations can be used to determine the price of the mower at each store is

t-2d=-240\\\\t-d=320

Hence, the correct option is "A."

What is the answer to the equation 5+2(x-1)=12
S_A_V [24]
5+2(x-1)=12 \\ \\ 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \\ \\ 2(x - 1) = 7 \ / \ simplify \\ \\ x - 1 =  \frac{7}{2} \ / \ divide \ each \ side \ by \ 2 \\ \\ x =  \frac{7}{2}  + 1 \ / \ add \ 1 \ to \ each \ side \\ \\ x =  \frac{9}{2} \ / \ simplify \\ \\

So, the answer to this problem is x = 9/2 or x = 4.5.

Can anyone plz solve this ?? -7 (1+3x) =4+5x
Aleonysh [2.5K]

Step-by-step explanation:

-7(1+3x) = 4 + 5x

-7 - 21x = 4 + 5x

(get all the variables on one side. Don't forget to change the signs)

-7-4 = 5x + 21x

-11 = 26x

(divide both sides by the coefficient [26])

26x/26= -11/26

x = -11/26
