3 x 50 = 150
1000 + 150 = 1150

2. 30 x 82
30 x 80 = 2400
30 x 2 = 60

Answer:

For the first one, it is 1150. For the second one, it is 2460.

Step-by-step explanation:

Think of 23 x 50 as (20 x 50) + (3 x 50).

20 x 50 is 1000. 3 x 50 is 150. 1000 + 150 is 1150.

Think of 30 x 82 as (30 x 80) + (30 x 2)

30 x 80 is 2400. 30 x 2 is 60. 2400+60 is 2460.

PT=y,TR=x+3,QT=2y,TS=3x-1 I'm confused and u really need help. My teacher isn't the greatest and wasn't much help.

Answer:

y=10, x=7

Step-by-step explanation:

Since the diagonals of a parallelogram bisect each other, PT should be equal to TR and QT should be equal to TS. So, y=x+3 and 2y=3x-1. Multiplying the first equation by 3 gives you 3y=3x+9. Using elimination to subtract these two equations gives you y=10. And since y=x+3, substitute y=10 there. 10=x+3, x=7.
