Average reading score is given by the expression,
y = 0.153x + 255.4
Here, x in the number of years past 1970.
To find the year in which the average reading score is 259.378, substitute the value of 'y' in the given expression.
y = 0.153x + 255.4
259.378 = 0.153(x) + 255.4
0.153x = 259.378 - 255.4
0.153x = 3.978
x = ![\frac{3.978}{0.153}](https://tex.z-dn.net/?f=%5Cfrac%7B3.978%7D%7B0.153%7D)
x = 26
That means given average reading score 259.378 will be 26 years after 1970.
Therefore, 1996 is the year in which the average reading score will be 259.378.

So we just do
cost/number of people=cost per 1 person
so
(6p)/(3p^2)
remember that you can split it up and make ones
![\frac{6p}{3p^{2}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6p%7D%7B3p%5E%7B2%7D%7D%20)
=
![\frac{6}{3p}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B3p%7D%20)
times
![\frac{p}{p}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bp%7D%7Bp%7D%20)
=
![\frac{2}{1p}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B1p%7D%20)
times
![\frac{p}{p}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bp%7D%7Bp%7D%20)
times
![\frac{3}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B3%7D%20)
=
![\frac{2}{1p}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B1p%7D%20)
times 1 times 1=2/p
easy way is
remember that
(x^m)/(x^n)=x^(m-n)
so
(6p)(3p^2)=6/(3p=2/p=2p^-1
each member pays 2/p
Answer:
19.2
Step-by-step explanation:
<u>1st Case:</u>
4 and 5 are legs of the right triangle.
Using the pythagorean therom: a^2+b^2=c^2
We can say that 4^2+5^2=x^2
16+25=x^2
41=x^2
x=√41
√41 is about 6.4
x=6.4
<u>2nd Case</u>
5 is the hypotenuse of the right triangle and 4 is the legs.
Using the pythagorean therom: a^2+b^2=c^2
We can say that 4^2+x^2=5^2
16+x^2=25
x^2=9
x=3
<u>Final Step</u>
We need to multiply the two possible lengths for x. So for case 1 the length of x was 6.4 and for case two the length was 3. 6.4*3=19.2
