Answer:

The first option

Step-by-step explanation:

First, multiply the fractions in the parentheses. To do this, multiply the numerators (3 * 4) and the denominators (4 * 9)

You get the fraction 12/36, which you can simplify as 1/3.

Now add -1/2 to 1/3.

First, find a common denominator. If you multiply 2 by 3, you get 6. Multiply the numerators by the same number you multiply the denominators by. In -1/2, you multiply 2 by 3 to get 6. So multiply -1 by 3 as well. You get -3/6.

Do the same with 1/3. To get the denominator of 6, you multiplied by 2, so do the same to the top. You get 2/6.

Now just add -3/6 + 2/6 (or subtract 3/6 from 2/6). You get -1/6, so it's the first option.

The average reading score on certain tests is given by y = 0.153x + 255.4, where x is the number of years past 1970. In what yea

nirvana33 [79]

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 = $\frac{3.978}{0.153}$

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.

Write an expression in factored form that is equivalent to the given expression. 1/2x + 4 . can u also tell how you solved it ?

Rufina [12.5K]

2 ways: Easy and hard
Hard=A
Easy=B
A: 1/2x+4 work from there so we do fun stuff with it make something that can be simplified so 1/2x+4 times (2/2)=x+8 now square the whole thing and put the result in a square root thingie (x+8)^2=x^2+16x+64 $\sqrt{x^2+16x+64}$ multiply the whole thing by 4/4 and put $\sqrt{16} [\tex] on top so then 
[tex] \sqrt{x^2+16x+64}$ times $\frac{ \sqrt{16} }{4}$ = $\frac{\sqrt{(16)(x^2+16x+64)}}{4}$ = $\frac{ \sqrt{16x^2+256x+1024} }{4}$ to solve it, factor out the 16 in the square root and then square root 16 to get 4 then it will be (4 times square root of equation)/4=square root of equatio factor square root of equation and square root it and get x+8 divide by 2 to get 1/2x+4

B: 1/2x+4
put stuff that cancels out
1/2x+3x-3x+4+56-56
move them around
3 and 1/2x-3x+60-56
or
2x-3x+1 and 1/2x+30-20+30-36
then just add like terms to solve
