Answer:
10 pastries
Step-by-step explanation:
To find how many they made in 1 hour, divide 35 by 3 1/2
35/3.5
= 10
So, he made 10 pastries in 1 hour
-7 > = 13 - 5x
-7 - 13 > = -5x
- 20 > = -5x....divide both sides by -5, changing the inequality sign
-20/-5 < = x
4 < = x......or x > = 4 <=== its C
Answer: x = -1
Step-by-step explanation:
You need to convert to the same base
![\frac{1}{16} = \frac{1}{2^{4} } = 2^{-4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B16%7D%20%20%3D%20%5Cfrac%7B1%7D%7B2%5E%7B4%7D%20%7D%20%3D%202%5E%7B-4%7D)
So
![2^{-4} = 2^{-2x-6}](https://tex.z-dn.net/?f=2%5E%7B-4%7D%20%3D%202%5E%7B-2x-6%7D)
For these values to be equal, the exponents have to be equal
-4 = -2x - 6
2 = -2x
x = -1
