3[x + 3(4x - 5)] = 15x - 24
3(x + 12x - 15) = 15x - 24
3(13x - 15) = 15x - 24
39x - 45 = 15x - 24    |add 45 to both sides
39x = 15x + 21      |subtract 15x from both sides
24x = 21      |divide both sides by 24
x = 21/24
x = 7/8

Answer:

A pint of veggies is approximately $1.75

Step-by-step explanation:

(7 × 2.85) + 5v = 28.70. 19.95 + 5v = 28.70. 5v = 28.70 - 19.95. 5v = 8.75. v = 8.75/5. v = 1.75

Hope this helps!!

Hello from MrBillDoesMath!

Answer:

-9 sqrt(5)


Discussion:

-2 sqrt(20) -  sqrt(125) =

-2 *2 sqrt(5) - sqrt(125)=                                as 20 = 4* 5

-4sqrt(5)- 5 sqrt(5)  =                                      as 125 = 25 *5

(-4 -5) sqrt(5) =

-9 sqrt(5)


Thank you,

MrB
