Answer:
10 and 42
Step-by-step explanation:
The difficulty with word problems is translating them into math.
Let's do that
---------------------
The sum of a number and two times a smaller number is 62.
let's call the bigger number b, and the smaller number s
b + 2s = 62
Three times the bigger number exceeds the smaller number by 116
3b = s + 116
-----------------------
Now manipulate one of the equations to isolate the variable
3b = s + 116
Subtract 116 from both sides
3b - 116 = s
substitute for s = 3b - 116 in
b + 2s = 62
b + 2(3b - 116) = 62
Distribute
b + 6b - 232 = 62
combine like terms
7b = 294
Divide both sides by 7
b = 42
to find s plug in b = 42 into
b + 2s = 62
42 + 2s = 62
subtract 42 from both side
2s = 20
divide both sides by 2
s = 10

Answer: k=1
Step-by-step explanation:
4 - 2k = 2
If it's easier you can also write it like
-2k + 4 =2
Solve for k by isolating it. Move four and then divide the -2.
-2k =2-4
-2k= -2
k= -2/-2
k=1
Answer:
Hello your question has some missing information below is the complete question
answer :
Step-by-step explanation:
Red car and Blue car take up 2 spaces each
Green cars take up 1 space
<u>lets determine the number of ways of filling up the parking spaces</u>
i) First lets assume the last space is filled by Green car then there will be 
space occupied hence there will be ( n - 1 ) spaces left to be filled in 
ways
ii) lets assume the last space is filled by either a Red car or a Blue car then there will be 
parking space occupied hence there will be
( n - 2 ) spaces left to be filled in 
ways
<u>Hence A closed formula for </u>
<u> </u>
where : a1 = 1 way , a2 = 3 ways
