Answer:
x=35
Step-by-step explanation:
When a is parallel to b, the two angles will add to 180
x+ 3x+40=180
Combine like terms
4x+40 =180
Subtract 40 from each side
4x= 180-40
4x= 140
Divide by 4
4x/4 = 140/4
x=35
36/48 simplified is 3/4
divide both by 12
36÷12

Answer: There are 16 million different phone numbers possible.
First, let's find the number of possible phone numbers without the area code. There are 7 numbers in a phone number. There are 10 digits for each position. However, the first one can't be 1 or 0, so there are only 8 options.
Multiply the possibilities to find the total number.
8 x 10 x 10 x 10 x 10 x 10 x 10 = 8,000,000
Since, there are 2 different area codes, just multiply 8 million by 2 to get 16 million.
