Tyler is 9 years old his sister Olivia is 6 years less than twice his age writ a numerical expression for Olivia’s age
liberstina [14]
Hello there!

The following will show you

T = tyler

O = olivia


O = 2t - 6

when you include numbers, it is represented by:

O = (2 * 9) - 6

Now, let's solve this to find out just how old Olivia is.

2 * 9 = 18

18 - 6 = 12

Olivia is 12

This means that olivia is 3 years older than tyler

I hope I helped!

The seventh grade class supplied bags of snacks and beverages for the school dance They supplied19 more beverages than bags of s
Delvig [45]

Answer:

The number of number of bags of snacks = m  = 176

The number of beverages supplied = m + 19  = 176 +9 = 185

Step-by-step explanation:

Let us assume the number of bags of snacks = m

So, the number of beverages supplied = m + 19

Total number of items supplied  =  371

⇒ Number of (snacks + beverages) supplied=  371

⇒   m + (m +19)  = 371

or, 2 m = 371 - 19 =  352

or, m =  352 / 2 = 176  

⇒  m  = 176

Hence the number of number of bags of snacks = m  = 176

So, the number of beverages supplied = m + 19  = 176 +9 = 185
