Answer: A) is the right answer. 
Step-by-step explanation:
Given product : 
To multiply above expression, first we need to combine like terms and then we need to use the law of exponents.
![2.3\times3\times10^{-3}\times10^8\\=(2.3\times3)\times(10^{-3}\times10^8)\\=6.9\times10^{-3+8}......[\text{by law of exponents }a^n\cdot\ a^m=a^{m+n}]\\=6.9\times10^{5}](https://tex.z-dn.net/?f=2.3%5Ctimes3%5Ctimes10%5E%7B-3%7D%5Ctimes10%5E8%5C%5C%3D%282.3%5Ctimes3%29%5Ctimes%2810%5E%7B-3%7D%5Ctimes10%5E8%29%5C%5C%3D6.9%5Ctimes10%5E%7B-3%2B8%7D......%5B%5Ctext%7Bby%20law%20of%20exponents%20%7Da%5En%5Ccdot%5C%20a%5Em%3Da%5E%7Bm%2Bn%7D%5D%5C%5C%3D6.9%5Ctimes10%5E%7B5%7D)
Thus, the answer is
.
Answer:
y=4x-22
Step-by-step explanation:
Answer: Choice B) -5.2 degrees
=====================
Work Shown:
Add up the given temperatures
-42 + (-17) + 14 + (-4) + 23 = -26
Then divide by 5 since there are 5 values we're given
-26/5 = -5.2
Answer and Explanation:
Five one-step equations with the answer of 0:
1. x - 8 = -8
2. x - 4 = -4
3. x / 2 = 0
4. x - 3 = -3
5. 5 * x = 0
Five one-step equations with the answer of -5:
1. y + 2 = -3
2. y - 3 = -8
3. y + 10 = 5
4. y * (-2) = 10
5. y / 1 = -5
Five one-step equations with the answer of 4:
1. 4 * z = 16
2. 8 - z = 4
3. 7 + z = 11
4. z / 2 = 2
5. z + 11 = 7
Hope these help!
