Step-by-step explanation:
9 = x/12
We will multiply 12 by 9
12 × 9 = x
108 = x
Yeah, they're equal.
8 * 3 = 24 and 8 * 4 = 32
so 24x+32 = 24x+32
Hey Friend! :) Let's work this out!

Hope this helps! (Don't forget Brainliest) :)
Step-by-step explanation:
comvert units into one unit
4ft 2in = 4 + 2/12 ft
3ft 4in = 3ft + 4/12ft
Know that the ratio of tan(x) = O / A
and set up proportions

solve for h
Answer
39 bills of 1$
16 bills of 10$
Step-by-step explanation:
x-nr of $1
y-nr of $10
x*1+y*10=199
x+y=55 , x=55-y
so I use the substitution method
(55-y)*1+10y=199
55+10y-y=199
-55 -55
9y=144
y=144/9
y=16
so x=55-16
x=39
verify 16*10+39*1=160+39=199
