Answer:
0.45
Step-by-step explanation:
Step 1:

Step 2:
8 · x = 0.3 · 12
8x = 3.6
Last Step: Divide both sides by 8 to isolate the value x
Answer:
x has no value
Step-by-step explanation:
me+you=20
3/4
The easiest way to solve this is to test the numbers one by one. 2/3 is not the answer because 2/3 times 3/2 is 1, not 9/8. It is 3/4 because 3/2 times 3/4 is 9/8, 9/8 times 3/4 is 27/32, and so forth.
In this question, you are given the temperate change (increase 2.5 degrees) and the duration (50 years). You are asked the rate of change which has a unit of temperature/year. Then to find it, the calculation would be:
rate of change= temperature change / duration
rate of change= 2.5 degrees / 50 years = 0.05 degrees / year
