answer
x=6,y=14
Step-by-step explanation:
make -5x+5x=40 as equation (1)
4x+3y=24...... (2)
Find equation (3) from (1)
-5x+5y=40
-5x/-5=(40-5y)-5
x= y-8............. (3)
Substitute (3) from (2)
4x+3y=24
4 (y-8)+3y=24
4y-32=24
4y=24+32
4y=56
y=14
find x from equation (3)
x=y-8
x=14-8
x=6
40/60= 0.67 (i.e. 2/3)= about 66.67%
I think you can chose your own points like (0,296) and (2,592)
Yes because it is an all real numbers equation.
You need to multiply 2.25 by 80 and it will equal 180 so the answer is....you need to sell 80 keychains. Hope i helped :-)
