Answer: A.71

Step-by-step explanation: 1.set up the equation

2. 4n-18+n+9=151-5n

3.combine like terms ->  5n-9=151-5n

4.solve for n

5.10n=160

n=16

now you have to plug 16 in for n in order to get the remote exterior angle.

151-5(16)

151-80

3. ms. Johnson placed two different orders with TR's special item store. each order was for 40 jars with the circus logo imprint
denis23 [38]
1.The height is 6 inches ad the width (diameter) is 3 inches!
2. So the jars are Volume ≈  42.41 inches so each boy needs 200 / 42.41 which equals approximately 4.72 inches per jar. So if wach boys have half the amount of jars which is 20 you multiply 20 by 4.72 which is 94.4 inches for each boy!

A factory can assemble 150 cars in 3 hours. At this rate, how many cars can be assemble in 8 hours?
Orlov [11]
To find this out first we will see how many cars they assemble in 1 hour. Lets do it:-

150 / 3 = 50
50 cars per hr
 
50 * 8 = 400
400 cars in 8 hrs
 
CHECK OUR WORK;-
 
400 / 8 = 50
We were RIGHT!!
 
So, in 8 hrs the factory can assemble 400 cars.
 
Hope I helped ya!! xD
