if you meant to put
, then the answer is 7
Step-by-step explanation:
h=-2
+32
solve for t
0=-2
+32
subtract 32 from both sides
-32=-2
divide both sides by -2
16=
find suare root of 16
4= t-3
add 3 to both sides
7 = t
Answer: 2405970 ways
Step-by-step explanation:
When the order of selecting r individuals out of n individual , we use permutations.
The number of permutations of r things taking out of n things is given by :-

Given : There are 135 people and three door prizes .
i.e. n= 135 , r= 3
Then, the total number of ways = 

Hence, there are 2405970 ways to distribute door prizes of $7,500, $750 and $75 .
Answer:
x = 11/2
Step-by-step explanation:
We would first put it in an equation
5x - 1 = 10 + 3x
We would first add 1 on both sides
5x = 11 + 3x
Then we subtract 3x on both sides
2x = 11
Divide both sides by 2
x = 11/2
the algebraic expression is 4(0.25)+2x=17
STEP 1: Simplify both sides of the equation
1+2x=17 or 2x+1=17
STEP 2: Subtract 1 from both sides
2x=16
STEP 3: Divide both sides by 2
2x/2 = 16/2
x=8
