Answer 2

for problem #1...1/8y + 10 = 14 1/8

whatever you do to one side, u have 2 do 2 the other and since you are trying equal it out, u have subtract 10 because 10 -10 = 0 so...
1/8y +10 = 14 1/8
- 10 =-10
-------------------------
1/8y = 4 1/8

now, do the same thing...if u r multiplying there than, u have to divide. u r trying to find y by itself

1/8y = 4 1/8
----- ------
1/8 = 1/8

y = ?

how many time will 1/8 go into 4 1/8


y = 33

Answer 3

(problem #1) 1/8y + 10 = 14 1/8
1/8y = 4 1/8
y=33

(problem #2) 1/2 x h x (a+b)
1/2 x 4 x (7+13)
1/2 x 4 x 20
40

(problem #3) you need to explain what you are talking about more thouroghly because i do not understand this question

Answer 4

of the top of my head i can only answer the first one

(1/8y +10)=14 1/8 0r 113/8

mutiply both sides by 8

y +80 = 113

subtract 80 from each

y=33
