To solve an equation for one variable, we will utilize PEMDAS ( parentheses, exponents, multiplication/division, add/subtract) but backwards. So we will first add/subtract any numbers to the other side to get the variable by itself. We will then divide/multiply any numbers to get the variable by itself.
Answer: d. 102
Why
If 6 is 78 then 5 is 102 and since 1,3,5,and 7 are equal 3 is 102. [180-78=120(180 is the straight line)]
Answer:
It will return 31.5 ft
Step-by-step explanation:
Here, the function is as follows;
let the yard be represented as y and the f be the feet
It takes in yards and return feet
Mathematically, using the relation between the two;
So for every yards it takes in, it returns 3 times the value in feet
Thus, for 10.5 yards, what it will return will be;
10.5 * 3 = 31.5 ft
<span>It's 1/r!
nCr = n! / r!(n-r)!
nPr = n! / (n-r)!
If you divide the two you'd have:
n! / r! (n-r)! * (n-r)! / n! = 1/r!
