Answer:
0=0
Step-by-step explanation:
Simplifying
-5(x + -7) = 35 + -5x
Reorder the terms:
-5(-7 + x) = 35 + -5x
(-7 * -5 + x * -5) = 35 + -5x
(35 + -5x) = 35 + -5x
Add '-35' to each side of the equation.
35 + -35 + -5x = 35 + -35 + -5x
Combine like terms: 35 + -35 = 0
0 + -5x = 35 + -35 + -5x
-5x = 35 + -35 + -5x
Combine like terms: 35 + -35 = 0
-5x = 0 + -5x
-5x = -5x
Add '5x' to each side of the equation.
-5x + 5x = -5x + 5x
Combine like terms: -5x + 5x = 0
0 = -5x + 5x
Combine like terms: -5x + 5x = 0
0 = 0
Solving
0 = 0
Couldn't find a variable to solve for.
This equation is an identity, all real numbers are solutions.
To figure out the degrees, you would create a ratio.
Since there are 360 degrees in your circle, that would be representative to 100 (because both are the total of what you want to find), and x would be representative to what degrees 65 is equal to.
your ratio should look like,
65/100=x/360
cross multiply and get
65(360)=100x
23400=100x
x=234
It looks hard to read like this, but if you write it out on your paper it should make more sense!
To solve this problem, we are going to set up an equation. Let the number that we are trying to find be represented by the variable x. If we plug in the numbers that we know, we get the following equation:
3x/4 = 24
To simplify this equation, we need to multiply both sides by 4, to begin getting the x alone on the left side of the equation.
3x = 96
Finally, we need to divide both sides by 3, to get rid of the coefficient that is being multiplied to x.
x = 32
Therefore, the number that you are trying to find is 32.
Answer: 77°
Step-by-step explanation:
First we are going to find x and then insert it in 18x +5 to be able to get our <WZX
But to find x, we will have to apply the the exterior angle theorem
The exterior angle theorem state that : the exterior angle is equal to the sum of the two opposite interior anges
Using this theorem, then from the diagram above ;
18x + 5 = 48 + 8x - 3
we collect like term
18x - 8x = 48-3-5
10x = 40
Divide bothside by 10
10x/10 = 40/10
x = 4
but <WZX = 18x + 5
Then we substitute x=4
<WZX = 18(4) + 5
<WZX = 72 +5
<WZX =77
Therefore the measure of <WZX is 77°

<u>Answer</u><u>:</u><u>-</u></h2>
Jessica sells = 240 books,
Josh sells = 16 books.
<h3>
Given:-</h3>
The price of one book is = $15
Jessica sold 15 times more books than Josh.
In total, they have sold 256 books.
<h3>Solution:-</h3>
We can easily find the answer using variables.
Let,
Josh sold a total of x books whereas Jessica sold a total number of 15x books.
together they sold 16x books.
So we can form the equation
16x= 256
by solving this equation we will get x=16
So, Josh sold 16 books and Jessica sold 16×15=240 books in total.
