Please solve this proportion with steps (I'm stuck)
(9x+6)/18= (20x+4)/3x

Answers

Answer 1

Answer: $(9x+6)/(18)=(20x+4)/(3x)$

Cross multiply. Distribute...
$3x(9x+6)=18(20x+4)\n27x^2+18x=360x+72\n27x^2-342x-72=0\n3x^2-38x-8=0$

OH GOD IT'S A QUADRATIC
(our equation is in ax² + bx + c = 0 form. a=3. b= -38. c= -8.
plug these values into the quadratic formula and simplify.)
$x=(-b\pm√(b^2-4ac))/(2a)=(-(-38)\pm√((-38)^2-4(3)(-8)))/(2(3))=\frac{38\pm√(1444+96)}6\n\n√(1444+96)=√(1540)=√(4*345)=2√(345)\n\n\frac{38\pm2√(345)}6=\boxed{x=\frac{19\pm√(345)}3}$

Approximate values for x: -0.20714 or 12.874

Answer 2

Answer:

First, distribute your like terms, which in this case is 'x'

you should get (9x+6)/18= 60x + 12

then you have to multiply both sides by 18 to get rid of the fraction

you should then get 9x+6= 1080x + 206

next, subtract 9x from 1080x, you should get 1071x

then subtract 206 on the side the 6 is on and you should get -200=1080x

divide both sides by 1080 and you should get x=0.19

For future preferences use PEMDAS = Parentheses, exponents, multiplication, division, addition, and subtraction. (Yeah, I know I didn't do it in that order)

basically, factor
first distribute
a(b+c)=ab+ac

p(c-d)=pc-pd

now we have
pc-pd+c-d
grou the c's with c's and d's with d's
(pc+c)+(-pd-d)
undistribute c's and -d's
c(p+1)-d(p+1)
undistribute with (p+1) as the a
(p+1)(c-d)

tada

(p+1)(c-d)

the answer is pc-pd +c-d hope this helped

Jeff had reached the highest level in his new computer game. The computer reported his score as 1.35x10^5 points. How should Jeff write his score in standard form?

Answers

Answer:

135,000 points

Step-by-step explanation:

An easier way to solve these type of questions is to understand that the $10^(5)$ is basically asking you to move the decimal point 5 spaces to the right, adding a zero in every free spot. So 1.35x10^5 would be

1.35x10^5 = 135000

In other words Jeff's high score written in standard form would be 135,000

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

you have to use pemdas or as other people call it ...

(p)lease (e)xcuse (m)y (d)ear (a)unt (sa)lly
parenthesis exponents multiply divide add subtract
you start with the exponent and you take 10 to the 5th power
that will equal 100000
so now you have 1.35x100000=135000
