To do this, first divide 85 by 10

You get 8.5

Then, divide 391 by 8.5

You get 46

Therefore, 46 students are left-handed in Tom's school.

johnathan class has 30 boys of the students in his class 60% are girls how many girls are in johnathans class
Gekata [30.6K]

Answer:

45 girls

Step-by-step explanation:

If 60% of the class is girls then 40% of the class is boys.

30 boys are in the class, meaning that 40% of the class comprises those 30 boys

First, we need the total number of class members: 30/x = 40/100 -> 40x=3000 -> x=3000/40 -> x=75

Now that we know the total class members, at 75, we can calculate the number of girls in the class. You can do this:

0.6*75=45

or

60/100=x/75 and solve for x

(X-3) (2x-3)= (x-3) (x+1) solve for x
yanalaym [24]

(x  - 3)(2x - 3) = (x - 3)(x + 1)

Do the multiplication both sides,

2 {x}^{2}  - 9x + 9 =  {x}^{2}  - 2x - 3

Arrange the terms to LHS according to their variables,

2 {x}^{2}  -  {x}^{2}  - 9x  +  2x + 9 - 3 = 0 \\  {x}^{2}  - 7x  + 6 = 0


Factorise this polynomial

{x}^{2}  - 6x - 6x + 6 = 0 \\ x(x - 6) - (x - 6) = 0 \\ (x - 1)(x - 6) = 0


So what we notice here is when you're multiplying two numbers you're getting 0 as answer.

So one of them must be 0.

If (x-1) is 0
then x = 1

similarly,

x-6=0

then, x= 6.


So the possible values of x are 1 and 6.

Help me plz. I dont understand.
Ahat [919]
For this, you would use simultaneous equations.

w=walnuts
a=almonds

3w+6a=51
5w+4a=55

Find a way to make one of the unknowns equal. since we are trying to work out the price of a pound of walnuts, I am going to make a equal on each side to leave us with w. This leaves us with:

15w+12a=165
6w+12a=102

Then take them away to leave w:

9w=163

Then solve:

w=163/9
= 18.11111111...

Then round it to 2 decimal places as the measurement is currency.

So 1 pound of walnuts equals $18.11
