2.5y + 3x=7 (1st)
5x - 2.5y = 5 re-write -2.5y + 5x = 5 (2nd)
2.5y + 3x=7 (1st)
-2.5y + 5x = 5 (2nd)
---------------------------add
8x = 12
x = 12/8 = 1.5
2.5y + 3x=7
2.5y + 3(1.5)=7
2.5y = 7 - 4.5
2.5y = 2.5
y = 1
answer
solution (1.5 , 1)
Answer:
C, I and II
Step-by-step explanation:
Removing one paperclip or one candy from a container leaves less in the container. This raises the probability of picking a specific item from the bunch.
ex. There's 5 rocks in a box. 20% chance to pick each one. Remove one of the rocks and the percentage rises to 25%. Now there's a higher chance to pick one specific rock.
Answer:
the answer is the first graph on the top row on the left (the one that says x=2,4,6,8, and y=7,9,11,13)
Step-by-step explanation:
a way you can find out is to put these points on a website called desmos and it can help you show which table is a linear function or just making your own graph
18% + 8.5% = 26.5% which is close to 25%
25% of 40 is 10, 40 +10 = 50
so the total bill would be just over $50
real cost:
40*0.085 = 3.40 = 40 + 3.40 = 43.40
43.40 *0.18 = 7.81, 43.40 + 7.81 = 51.21
