Answer:

Step-by-step explanation:

7√144 - 11√45 + 6√500

= 7(12) - 11√(9×5) + 6√(100×5)

= 84 - 11(3)√5 + 6(10)√5

= 84 - 33√5 + 60√5

= 84 + 27√5

Answer:

7√144 - 11√45 + 6√500 = 84 + 27√5

Step-by-step explanation:

7√144 - 11√45 + 6√500

= 7(12) - 11(√9×√5) + 6(√100×√5)

= 84 - 33 √5 + 6(10×√5)

= 84 - 33 √5 + 60√5

= 84 + 27√5

Answer:

Line D represents a proportional relationship.

Step-by-step explanation:

In an easy way to explain what a proportional relationship is, it is basically a line graph that passes through the origin point. When a line graph passes through the origin point (0,0), it is proportional.

Other graphs do not intersect the origin points so they are not proportional.

After a 20% price reduction, a cordless phone sold for $48. What was the phones price before the reduction?

GalinKa [24]

After 20% reduction the price is $48 which means $48 is only 80% of the original price...so let x= original price
48=.8x 
60=x 
it was $60
