option D
rent = 25b + 10
where b is hours for boat rented
85 = 25b + 10
25 b = 75
b = 75/25 = 3
It is given that
a+b=20 -------------------- (1)
b+c=30 -----------------------(2)
We have to calculate
3 a + 4 b +7 c
Now multiplying equation(1 )by 3,we get
3 a+ 3 b=60 ----------------------------------(3)
and Multiplying equation( 2) by 4,we get
4 b + 4 c=120 -----------------------------------(4)
Adding expression (3) and (4),we get i.e left hand side of 3 to left hand side of 4 and right hand side of 3 to right hand side of 4.
3 a+ 3 b+ 4 b+ 4 c=60+120
Adding like terms, we get
3 a+ 7 b+ 4 c =180, Which is the required solution.
Hey there!
y-12=20
Add 12 to both sides. (do the inverse of subtraction, which is addition)
y=32
Check answer.
32-12=20 <=== checks out :)
I hope this helps!
