Two cars that are 150 miles apart start driving toward each other on parallel roads. The average speed of the first car is 60 mi

les per hour. The average speed of the second car is 55 miles per hour. Which equation can be used to determine t, the time it takes for the two cars to pass each other?
A table showing Rate in mile per hour, Time in hours, and Distance in miles. The first row shows First Car and has 60, t, and 60 t. The second row shows Second Car and has, 55, t, and 55 t.

60t – 55t = 0
60t + 55t = 1
60t + 55t = 150
60t – 55t = 150

Answer:

60T + 55T = 150

Step-by-step explanation:

T(60+55)=150\\115T=150

T=150/115=1.304 hr

The cars takes 1.304 hrs (1h 18 min aprox) to pass each other

KIM [24]
To find the greatest possible product, you need the greatest possible numbers. The largest possible 2-digit number is 99. The largest possible 1-digit number is 9. Therefore, 99 * 9 will be the largest possible product under these circumstances.

99 * 9 = 891

Hope this helps! :)

Lalo has 1,500 minutes per month on his cell phone plan. How many more minutes can he use if he has already talked for 785 minut
Ket [755]

Answer:

715 minutes

Step-by-step explanation:

we know that

To find out how many more minutes he can use, subtract the number of minutes he has already talked from the number of minutes  of his plan

Let

x -----> the number of minutes  of his plan

y -----> he number of minutes he has already talked

so

x-y

we have

x=1,500\ min\\y=785\ min

substitute

1,500-785=715\ min

The process is similar to (and easier* than) adding three 4-digit numbers. Add the numbers in each column.

The sum is ...
  (2+1-3)x³ +(-4+6+2)x² +(6-8-4)x +(-3+12-7)
  = 0x³ +4x² -6x +2

The sum is 4x² -6x +2


_____
* The process is easier because there are no "carry" operations from one column to another as there may be when adding multi-digit numbers.
