Answer:
50
Step-by-step explanation:
4 black cards = 5C4 = 5
2 red cards = 5C2 = 10
5 x 10 = 50
3(3x+4)(2x+5)
Because you factor out the 3 and then factor 6x^2+23x+20
That becomes (6x^2+8x)+(15x+20)
Factor out a two from the left and five from the right.
That makes 2x(3x+4) + 5(3x+4)
That becomes (3x+4)(2x+5)
Then put the three back in front.
From my understanding, there are 124 5 dollar bills which would equal $620.
The total money of the value is $840 then you would subtract. $840-$620=$220.
Divide that by ten so, $220/10= 22.
She has 22 ten dollar bills.
<h3>Total number of students in Ms. Perron’s class is 25</h3>
<em><u>Solution:</u></em>
In Ms. Perron’s class, 40% of the students are boys
There are 10 boys in the class
Let "x" be the total number of students in Perron class
From given,
40 % of total students are boys
Therefore,
40 % of x = 10

Thus total number of students in Ms. Perron’s class is 25
