(2/7)^0= 1
(9)^0=1
i think that's what your asking if not let me know
C = 15n + 85....when C = 385
385 = 15n + 85
385 - 85 = 15n
300 = 15n
300/15 = n
20 = n <== 20 watches were made
Answer:
b = 43
Step-by-step explanation:
So let's plug things in first:
y= 2x - 20 and y= -5x +b which can become →
2x - 20 = -5x + b (now you said that x=9 so let's plug that in)
2(9) -20 = -5(9) + b (now try solving that)
18 -20 = -45 + b → -2 = -45 + b ( so then add 45 to both sides)
43 = b ( and there's your answer )
The quality is to bad, ask your teacher 15-19
Answer:
(86 – h) + h = 86
Step-by-step explanation:
$70+$260= $330
34 lemonade + 52 hot dogs = 86 items = $330
With 34 lemonade + 52 hotdogs h= 52
(86 – h) + h = 86 = 86-52+52=86
