nt / (n+t)
substitute n=15 and t=7
(15*7)/(15+7)
105/22
22 goes into 105 4 times with 17 left over
4 17 /22
Answer:
the defect percentage is 21% (i think)
Step-by-step explanation:
3x-8y=-35
- First thing you need move the 3x to the right hand like this one
-8y=-3x-35 ( positive move to another side change to negative )
And then you need to move -8 to the right hand to !
y=-3/-8 -35/-8 so you need to change the negative to positive y=3/8 + 35/8 ( 3/8 mean 3 over 8 )
The answer is y= 3/8 + 35/8
Answer:
see below
Step-by-step explanation:
The second equation tells us x = y - 3 so when we plug in y - 3 for x in the first equation we get 4(y - 3) + 3y = -5 → 4y - 12 + 3y = -5 → 7y = 7 → y = 1. Plugging this value into the second equation we get x = y - 3 = 1 - 3 = -2.
