Answer:

x = 15

Step-by-step explanation:

Given

3(2x + 5) = 3x + 4x ← collect like terms

3(2x + 5) = 7x ← distribute parenthesis on left side by 3

6x + 15 = 7x ( subtract 6x from both sides )

15 = x ⇒ x = 15

Answer:

The 3rd option

Step-by-step explanation:

The pattern is every 2 hours is $15 so 4 hours would be equal to $30

Since 4 hours would equal 30 and we need 12 hours multiplying both numbers by 3 would get you the answer

4x3=12

30x3=90

Making it equal

Factoring expressions: 17x-34xy
Katarina [22]

17x(1-2y)

17x-34xy

because both expressions have a x, it would be easier to factor out the x first. but because 17 is a factor of 34 you can simply divide 34 by 17 and get 2. so you put it together to this,

17x(1-2y)

Because, 17x times 1 is 17x but 17x times -2y would be -32xy.
