12 + v/5 = -3
step 1. subtract 12 from both sides...
v/5 = -15
step 2. Do the opposite operation, since your diving 5, multiply 5 and -15
v = -75
the variable 'v' equals -75
Answer:
The answer to your question is:
Step-by-step explanation:
1.-
Data
3.3 x 10 ⁴ pounds of paper
1.5 x 10³ pounds of aluminum
Amount of aluminum / amount of paper = 1.5 x 10³ / 3.3 x 10⁴
= 0.045 times
= 4.5 x 10 ⁻²
2.-
Data
1.2 x 10 ³ text messages in a month
text messages in a year = ?
1.2 x 10³ text messages ------------------- 1 month
x ------------------- 12 months
x = (12 x 1.2 x 10³) / 1
x = 14400 text messages
x = 1.44 x 10⁴ text messages
3.-
Data
distance = 4 x 10⁶ miles I am not sure if the power is 6 or 8
speed = 1.6 x 10³ mi/h
Formula
time = distance / speed
time = 4 x 10⁶ / 1.6 x 10³
time = 2500 h
time = 2.5 x 10 ³ h
You could multiply 1/4 by 3 and 1/6 by 2. You would get 3/12 and 2/12. The common denomonator is 12. 4 and 6 are both multiples of 12.
<1 and <2 are supplementary angles. They add up to 180 degrees.
92 and <2 are corresponding angles, they have the same measure.
So,<2 = 92 degrees
180-92= 88 degrees
<1= 88 degrees
I hope this helps!

Answer:
36, 45
Step-by-step explanation:
Using equations you get 
because one number is 9 more than the other and the sum is 81. Simplifying you get, 
. Divide both sides by 2 to get 
. Remember this is only x so to get the other number you have to add 9 to 36 to get 45 as the other number.
