Answer:
Step-by-step explanation:
1) y = 50x + 2500
2) y = 200x + 1000
if we build a system with the two equations, we have:
50x+2500 = 200x + 1000
150x = 1500
x = 10
y = 2000 + 1000 = 3000
3) 10
4) $3000
Answer:
72
Step-by-step explanation:
If he reads 24 pages in 1/3 of an hour, he reads 3 times as many pages in 1 hour.
3 × 24 pages = 72 pages
Answer: 72
4c+c+5c = 5c+5c= 10c
I added the single c to the 4c first to get another 5c then added the two 5c together to get 10c, since all terms have a single c in them all can be combined
Answer:
x = 19
Step-by-step explanation:
All triangle angles equal 180
3x + 9 + 2x + 4x = 180
9x + 9 = 180
9x = 171
x = 19
