Answer:
-52
Step-by-step explanation:
You can clear fractions by multiplying by 3:
3(1/3x) -3(2/3) = 3(-18)
x -2 = -54
add 2:
x = -52
Answer: 6.00 + 3.60x
Step-by-step explanation:
Regular coffee= 2.00 each
Letters= 3.50 each
Samantha buys 3 regular coffees and x letters.
To get the total amount she spends at the coffee shop, we multiply each quantity bought by the price. Therefore, total amount will be:
= (2.00×3) + (3.50×x)
= 6.00 + 3.50x
The expression for the amount spent at the coffee shop is 6.00+3.50x
Answer:
The LCM is 6
Finding the LCM will make them make the same number of brackets.
