Answer:
Price per pound for cashews = $7
Price per pound for peanuts = $4
Step-by-step explanation:
Let,
x be the price per pound of cashews
y be the price per pound of peanuts
According to given statement;
4x+2y=36 Eqn 1
7x+6y=73 Eqn 2
Multiplying Eqn 1 by 3
3(4x+2y=36)
12x+6y=108 Eqn 3
Subtracting Eqn 2 from Eqn 3
(12x+6y)-(7x+6y)=108-73
12x+6y-7x-6y=35
5x=35
Dividing both sides by 5
Putting x=7 in Eqn 1
4(7)+2y=36
28+2y=36
2y=36-28
2y=8
Dividing both sides by 2
y=4
Hence,
Price per pound for cashews = $7
Price per pound for peanuts = $4
Hmmm the increase, wel is just the difference 367 - 312, which is 55.
now, if we take 312 to be the 100%, what is 55 off of it in percentage?
Answer:
41) x = 8
Step-by-step explanation:
41)
Arc MN is 100 degrees because it is the double of 50 degrees.
12x+4=100
12x-4=100-4
12x=96
x/12=96/12
x=8
