Firstly the coefficient, or the number next to the variable, which is x, goes before it. So instead of x3, it's 3x.

So, to solve to find what x is, you need to divide by 3 on both sides of the equal sign.

3x=729

Dividing by 3 on the left cancels out the 3, leaving just the x.

Dividing the other side gets you what x equals.

x= 243

x3=729

729/3= 243

x=243

There is a total of 1,500 people in the town of Markston. Only 55% of them voted during the town's elections this year. How many
AfilCa [17]

Answer:

825 people voted in the town of Markston during the elections this year.

Step-by-step explanation:

Hi there!

The total number of people of the town of Markston (1500) is the 100%. Then, the 55% of 1500 can be calculated by multiplying 1500 by 55/100:

55% of 1500 = 1500 · 55/100 = 825

Another way to see this:

If 100% is 1500, then the 55% will be x:

100% -------- 1500

55% ----------- x = 55 · 1500 / 100 = 825

Then, 825 people voted in the town of Markston during the elections this year.

Have a nice day!

90 points!!! Algebra - Please check these
Korvikt [17]

First picture:

2 and 7 are alternate exterior angles, which when added together need to equal 180 degrees.

Angle 7 = 180 - 146 = 34

Answer is B.34

Second picture:

Angle 8 = 48

Angle 8  + angle 7 = 180

Angle 7 = 180 - 49 =  131

Angle 5 and angle 7 are vertical angle, so angle 5 = angle 7 = 131

Angle 6 is a vertical angle to angle 8 so = 49

Angle 1 = angle 5 = 131

Angle 2 = angle 6 = 49

Angle 3 = angle 7 = 131

Angle 4 = angle 8 = 49

What are the correct answers and why? Simple and concise explanation please!!!
dezoksy [38]

Answer:

\large\boxed{-\bigg[(x-3)^2+2x\bigg]+1}\\\\\boxed{-x^2+4x-8}

Step-by-step explanation:

(g\ \circ\ f)(x)=g\bigg(f(x)\bigg)

f(x)=(x-3)^2+2x\\\\g(x)=-x+1\\\\g\ \circ\ f\to\text{put f(x) instead of x in the function g(x)}:\\\\(g\ \circ\ f)(x)=-\bigg[\underbrace{(x-3)^2+2x}_{x}\bigg]+1

-----------------------------------------

-\bigg[(x-3)^2+2x\bigg]+1=-(x-3)^2-2x+1\\\\\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\=-(x^2-(2)(x)(3)+3^2)-2x+1=-(x^2-6x+9)-2x+1\\\\=-x^2-(-6x)-9-2x+1=-x^2+6x-9-2x+1\\\\\text{combine like terms}\\\\=-x^2+(6x-2x)+(-9+1)=-x^2+4x-8

-----------------------------------

-x^2+4x-8=-x^2+4x-2^2+2^2-8=-(x^2-4x+2^2)+4-8\\\\=-(\underbrace{x^2-(2)(x)(2)+2^2}_{(a-b)^2=a^2-2ab+b^2})-4=-(x-2)^2-4=-(x+1-3)^2-4

In\ (-x+1-3)^2+2x,\ x^2\ will\ be\ positive.\\In\ (-x+1-3)^2+2(-x+1),\ x^2\ will\ be\ positive.
