Imagine that the variable c represents something tangible, like an orange. So what this equation is asking is subtract 1 orange from 12 oranges. So you are left with 11 oranges.
Another way to think about this problem is if you rewrite the equation slightly to:
12c - c =
12c - 1c =
11c
Answer:
3 3/4 in length is equal to 22.5 picas
Step-by-step explanation:
If there are 6 picas in 1 in, then in 3 3/4 in, we will first take this to decimal form, which is
3.75 in
Therefor 3.75 in = 6 picas × 3.75 = 22.5 pisca
Answer:
B. The root/index.
Step-by-step explanation:
For example:
∛x = x^1/3
3 is the root index which becomes the denominator (3) of the exponent.
NH: UD=0 ; AH: UD<0.
U is a Greek letter but I don't have a Greek keyboard. Both D shapes are subscript. NH stands for null hypothesis, AH is for alternative hypothesis. Just took the test.
