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
2 separate 7 ft boards = (2 * 7) = 14 feet
1 ft = 12 inches....so 14 feet = (14 * 12) = 168 inches
168/11 = 15.27 <== she has 15 eleven inch boards.
Answer:
See below
Step-by-step explanation:
<u>Given function:</u>
m represents the domain and D represents the range of the function, therefore m = x, D = y
<u>Filling in the table:</u>
- for x = 10, y = 35 + 0.4*10 = 35 + 4 = 39 and so on for the rest of the values
- x = 10, 30, 50, 75, 100
- y = 39, 47, 55, 65, 75
