Answer: is there a picture so that i can help you figure out his equation
1) -15x-9y= -2
-9y = 15y-2
y = 15/9 - 2
2) -35x-5y= 14
-5y = 35x+14
y = -7x + 14
Answer:
0.1088 or 10.88%
Step-by-step explanation:
q = 1 - 0.35 = 0.65
P(X=2) = 12C2 × (0.35)² × (0.65)¹⁰
= 0.1088
Answer:
Step-by-step explanation:
hello :
3x − 2y = −9 ...(*)
4x + 3y = 22...(**)
multiply (*) by 3 and(**) by 2 you have : 9x-6y = -27
8x+6y =44
add this equations : 17x = 17 so : x=1
put this value in : 8x+6y=44
8(1)+6y=44
6y=36
y=6
one solution : (1 ; 6)
Simply find the total medium cofees sold
then divide that by the number of medium cofees that weren't caffeinated
so..
then
so x will be 1.5 & 100 ÷ 1.5 = 66.666...
rounded is 67%
