Abby has x dolls. Lauren has 9 times as many as Abby. Betsy has 7 fewer than Lauren. How many dolls do they have in all?
makkiz [27]

Answer: x + 9x + (9x - 7)

Simplified: 19x - 7

Step-by-step explanation: We see that Abby already starts off with x dolls. We put a 9 infront of the x for the second part of the expression because Lauren has 9 times as many dolls as Abby. Since Betsy has 7 less than Lauren, we take away 7 from 9x. We put that part in parenthesis because that part needs to be done first before we add everything together. Once simplified, we have "19x - 7". (I really tried my best so I hope this is the correct answer!)

Answer:

Option 2.

Step-by-step explanation:

The antifreeze claims to protect between -30 C and 130 C. The inequality should be this: -30

You can replace C with the Fahrenheit formula: C=\frac{5}{9} (F-32)

So, the inequality becomes -30
