Answer:
Natalie saved 16%
Step-by-step explanation:
Natalie saved 16% because 20 divided by 125 is 0.16
When we find percentages our goal is to get something like 0.24 which would mean 24% or 0.14 or 14% in this case it is perfect because we immediately see 0.16 or 16% leaving us with our answer, Natalie got 16% off her new phone.
Answer: first sawmill charges more for each meter of wood. And first mill has a cheaper price for 5-meter wooden beam.
Step-by-step explanation:
P=5+20x. The first sawmill charges $20. Then 110-20/5-0=18 Which means The second sawmill charges $18 for each meter of wood. Since 20>18 The first sawmill charges more for each meter of wood.
P = 5+20x
=5+20x•5
= 105
The first mill charges $105 For a 5 meter beam while the second beam charges $110
Answer:
The solution would be (6, 2)
Step-by-step explanation:
In order to solve this using elimination, simply add the two equations together.
2x + 3y = 18
3x - 3y = 12
-----------------
5x = 30
x = 6
And now that we have the value for x, we can solve for y.
2x + 3y = 18
2(6) + 3y = 18
12 + 3y = 18
3y = 6
y = 2
