1 mile is 5,280 ft, and 1 second has 1,000,000 microseconds.
So 186,000 miles per second multiplied by 5,280 feet per mile gives 982,080,000 feet per second.
Dividing this value by 1,000,000 microseconds per second gives the final answer of 982.08 feet per microsecond.
Answer: B. 
Step-by-step explanation:
1. By definition, the associative property of addition is:
2. Therefore, if you have the following expression:
You apply the Asociative property of addition by regrouping the numbers as following:
3. Then, you can conclude that the correct option is B.
x^2+6x-5=0
x^2=2x
2x+6x-5=0
2x+6x=8x
8x-5=0
+5 +5
(if you don’t know what I’m doing here is that I’m removing the negative 5 by putting a positive 5 since both of them make 0. Also the “x” always stay alone and the unit stays as the unit)
(I putted the positive under the 0 because what u do to the unit you need to do the same thing with the other.)
8x/8=5/8
(If ur lost here it means dividing.)
The answer
X=0.625
(btw I’m not really sure if this is right so um don’t really trust me in this lol)
<u>Slope -2/5.</u>
Answer:
Solution given:
(x1,y1)=(0,0)
(x2,y2)=(-2,5)
now
slope =(x2-x1)/(y2-y1)=(-2-0)/(5-0)=-2/5
Find the total price
original price × sales tax
33 × 0.04 = 1.32
Add original price & sales tax
33 + 1.32 = 34.32
