Answer:
<em>150</em>
Step-by-step explanation:
The ratio of boys to girls is 3 to 7.
We don't know the number of boys or girls. The number of boys and the number of girls are multiples of 3 and 7, respectively. Since they are in the ratio of 3 to 7, then by multiplying both 3 and 7 by the same number, you will get the number of boys and the number of girls. We need to find that number. Call that number x.
The ratio of boys to girls is:
3x to 7x
There are 3x boys and 7x girls.
The number of girls is 200 more than the number of boys.
7x = 3x + 200
Subtract 3x from both sides.
4x = 200
Divide both sides by 4.
x = 50
The number of boys is 3x, so
3x = 3(50) = 150
Answer:
x=0
Step-by-step explanation:
2x+4-6=
We move all terms to the left:
2x+4-6-()=0
We add all the numbers together, and all the variables
2x=0
x=0/2
x=0
The probability will be equal to P = 1 / 3.

What is probability?</h3>
Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Given that:-
Kenji and mary are members of a school committee that will be meeting this afternoon. the 6 members of the committee will be seated randomly around a circular table. what is the probability that Kenji and mary will not sit next to each other at the meeting
The probability will be:-
There are 6 positions so the total samples are 6 and two positions are locked because they will always seat opposite each other so the
The probability will be calculated as:-
Therefore the probability will be equal to P = 1 / 3.

Answer:
Expression please
Step-by-step explanation:
Add the expression or image/pic of your homework.
Answer:
f'(x) = 18x² - 18x + 12
Step-by-step explanation:
Differentiate using the power rule
(a ) = na
Given
f(x) = (3x² + 6)(2x - 3) ← expand factors using FOIL
= 6x³ - 9x² + 12x - 18 , then
f'(x) = 3.6x² - 2.9x + 12
= 18x² - 18x + 12
