the ratio of the number of kids is 4:7

that means for every 7 kids we have 4 adults

7 kids ---- 4 adults

the difference is 3

we dived the difference of the kids between the difference of the ratio

150/3 = 50

the number we obtained must be multiply by the ratio of each part

7(50) = 350 number of kids

4(50)=200 number of adults

there are 200 adults at the fun fair

What is 2 2/3 minus 1 1/2
vagabundo [1.1K]

Answer:

1 1/6

Step-by-step explanation:

2 2/3 = 2+2/3

1 1/2 = 1+1/2

So (2 2/3) - (1 1/2)=2+2/3-(1+1/2)=

2+2/3-1-1/2=1+(2/3-1/2)=1+(4-3)/6=1+1/6=

MrMuchimi

Answer:

Video Games = $5.25

Movies = $1.25

Step-by-step explanation:

(3x + 5y = 30)2

6x + 2y = 18

                                           Video Games (y) = 5.25

  6x + 10y = 60

<u>-  6x + 2y = 18   </u>

      (8y)/8 = (42)/8

<u>                                                                                </u>

6x + 2(5.25) = 18

6x + 10.5 = 18

6x = 7.5

x = 1.25

Find the value of x so that the function has the given value. f(x) = 6x + 9; f(x) = 21
Olin [163]

Answer:

x = 2

Step-by-step explanation:

We need to find the value of x so that the value of given function becomes 21 .

We have ,

f(x)=21\\\\ f(x)= 6x + 9

Now , for finding x ,

6x +9 = 21 \\\\ 6x = 21 -9 \\\\ 6x = 12 \\\\ x = 2

Factor the GCF: −12x4y − 9x3y2 + 3x2y3
monitta
Factor the coefficients:
-12=(-1)(3)(2^2)
-9=(-1)(3^2)
3=3

The greatest common factor (GCF) is 3

Next we find the GCF for the variable x.
x^4
x^3
x^2
The GCF is x^2.

Next GCF for variable y.
y
y^2
y^3
the GCF is y

Therefore the GCF is 3x^2y
To factor this out, we need to divide each term by the GCF,
(3x^2y)(−12x4y/(3x^2y) − 9x3y2/(3x^2y) + 3x2y3/(3x^2y) )
=(3x^2y)(-4x^2-3xy+y^2)     
if we wish, we can factor further:
(3x^2y)(y-4x)(x+y)
