Answer:
No.
Step-by-step explanation:
There are two different ways to do this - solve for x in the given equation or substitute the value for x and see if you get a true statement.
3x + 7 = 13 subtract 7 from both sides
3x = 6 divide by 3 on both sides
x = 2
3(3) + 7 = 13
9 + 7 = 13
16 ≠ 13
Therefore, x = 3 is not a solution for 3x + 7 = 13.

I'm not sure if your question was to find the number of girls, but if it was, here's the answer
Step-by-step explanation:
Total number of students= 572
number of boys= 5
So, number of girls= 572-5 =567 (ans)
Answer:
((x+3)^2)/49 - (y^2)/36 = 1
Step-by-step explanation:
Experimental probability is the chance an event has to occur. It is derived from the number of times an event occurs to the total number of trials. You can use the following formula to calculate it. P = (o/t) * 100%, where o is the number of times the event occurred, and t is the total amount of trials ran. In this case, P = (66/101) * 100, which evaluates to P = 65.3% (after rounding)
Answer: 65.3%
It’s the first one.
I hope this helps :)
