Positive numbers are always greater than -15. Therefore, it's a greater than.
-2x = - 15
Dividing both sides by -2, we get
x = 7.5
Negative cancels on both sides, so we get a positive equation.
Positive numbers are always greater than -15. Therefore, it's a greater than.
What is greater than or less than?
- Greater than and less than are the comparison symbols.
- When the number is bigger or smaller than the other, then greater than and less than symbols are used.
- If the number is greater than the other, the greater than (>) symbol is used.
- If the number is lesser than the other, the less than the (<) symbol is used.

Answer:
274560
Step-by-step explanation:
We can "choose" one of the 66 athletes for the gold medal. That athlete can't win any other medals, so there are 65 athletes left.
We can then "choose" one of the 65 athletes left for the silver medal. That athlete can't win any other medals, so there are 64 athletes left.
We can then "choose" one of the 64 athletes left for the bronze medal.
That leaves us with 66 possible choices * 65 possible choices * 64 possible choices=274560 possible choices
It’s using the distributive method. 7 x a is 7A and 7 x 13 is 91, therefor it is 7A+91.
Answer:
237
Step-by-step explanation:
This is a system of equations.
The theater sold 364 adult and child tickets, so a + c = 364
They made a total of $1930. Each adult ticket was $6 & child tickets were $4. The second equation is 6a + 4c = 1930.
Let's line them up
a + c = 364
6a + 4c = 1930
Since we need to solve for the number of adult tickets, we want to get rid of the c variable. I'm going to multiply the entire first equation by -4 to do this. The second equation stays the same. Now, I have:
-4a - 4c = -1456
6a + 4c = 1930 Add them together
----------------------
2a = 474 Divide by 2 to solve for a
a = 237
There were 237 adult tickets sold
