Pi aka 3.14 is a very commonly know irrational number
Answer:
True
Step-by-step explanation:
Key idea: the graph of a proportional relationship is a straight line through the origin.
Answer: the answer is x=72
Step-by-step explanation:
Step 1: simplify both sides we know 15=x/4 -3 (the x holds a invisible 1)
the equation should look something Like: 15=1/4x-3 then FLIP the equation such as:
1/4x-3=15 then add 3 on both sides so 15+3=18
step 2: our equation is now 1/4x=18 (we see 4 is being divided the opposite of division is multiply) therefor multiply the 18 with 4
18*4=72 which means x=72
The constant potion contains no variables ( no 'x')
So its 16
