(x − 106) = 12 + 7x
Answer:
X=−10
Step-by-step explanation:
i hope this helps you ^_^
have a nice day/night
Equation/Question:
1/2(x-106)=12+7x
Answer/Steps to answer: (x= -10)
1. Simplify 1/2(x-106) to x-106/2.
x-106/2=12 + 7x
2. Multiply both sides by 2.
x−106=24+14x
3. Subtract x from both sides.
−106=24+14x−x
4. Simplify 24+14x-x to 24+13x.
-106=24+13x
5. Subtract 24 from both sides.
-106-24=13x
6. Simplify -106-24 to −130.
-130=13x
7. Divide both sides by 13.
130/13=x
8. Simplify 130/13 to 1010.
-10=x
9. Switch sides.
x=-10
-------------
Checking:
1/2(x−106)=12+7x
1. Let x=-10x=−10.1
1/2(−10−106)=12+7×−10
2. Simplify -10-106 to −116.
1/2×−116=12+7×−10
3. Move the negative sign to the left.
-116/2=12+7×−10
4. Simplify 116/2 to 58
−58=12+7×−10
5. Simplify 7×−10 to −70.
−58=12−70
6. Simplify 12-70 to −58.
−58=−58

Express f(x)=3+|2x-5| as a piecewise function WITHOUT using absolute value
Please give a detailed response not just answer to help me understand
Answer:
[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)=3+|2x-5|[/tex]
Remember that by the definition of absolute value:
[tex]\displaystyle |x|= \left\{ \begin{array}{ll} x & \quad x \geq 0 \\ - x & \quad x < 0 \end{array} \right.[/tex]
Our absolute value is:
[tex]|2x-5|[/tex]
First, we will find when it becomes 0. Set the equation equal to 0:
[tex]2x-5=0[/tex]
Solve for x:
[tex]x=5/2[/tex]
So, we can see that for all values greater than x = 5/2, 2x - 5 is positive.
For all values less than x = 5/2, 2x - 5 is negative.
Therefore (the positive case go above, and the negative case go below):
[tex]|2x-5|= \left\{ \begin{array}{ll} 2x-5 & \quad x \geq 5/2 \\ -(2x-5) & \quad x < 5/2 \end{array} \right.[/tex]
Finally, we can add a three:
[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 3+(2x-5) & \quad x \geq 5/2 \\ 3+(-(2x-5)) & \quad x < 5/2 \end{array} \right.[/tex]
Simplify if desired:
[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.[/tex]

=
[tex]8 \times {2}^{2} \div 2[/tex]
STEP 2:
Calculate Exponents:
[tex] {2}^{2} = 4[/tex]
=

6. Two numbers are in the ratio of 2:3 If the bigger number is 6. what is the smallest one
_7. What number compared with 6 is the same as 36 compared to 6?
8. There are 24 red roses for every 6 roses. How many red roses are there if there
are 8 roses?
9.There are 7 children for every 2 adults in a plaza. How many adults are there,
if there are 21 children?
10.1f 12 pencils are bought for P60, how much will you pay for 25 pencils
Ratio of two numbers = 2:3
The larger number = 6
Let the smaller number be x.
Which means :
[tex] =\tt 2 : 3 \: = \: x : 6[/tex]
[tex] = \tt \frac{2}{3} = \frac{x}{6} [/tex]
[tex] =\tt 2 \times 6 = 3 \times x[/tex]
[tex] =\tt 12 = 3x[/tex]
[tex] =\tt x = \frac{12}{3} [/tex]
[tex]\hookrightarrow\color{plum}\tt \: x = 4[/tex]
▪︎Therefore, the smaller number = 4
○=> Solution (7) :36 compared to 6 = [tex] \tt \frac{36}{6} [/tex]
Let the number be x.
Which means :
[tex] = \tt \frac{36}{6} = \frac{x}{3} [/tex]
[tex] =\tt \frac{36 \div 2}{6 \div 2} = \frac{x}{3} [/tex]
[tex] =\tt \frac{36}{6} = \frac{18}{3} [/tex]
▪︎Therefore, the fractional number [tex] \tt \frac{18}{3} [/tex] is equal to [tex] \tt \frac{36}{6} [/tex].
○=> Solution (8) :Number of Rose's for 24 red Rose's = 6
This can be written in a ratio as 24:6
Number of roses = 8
Let the number of red roses for these roses be x.
Which means :
[tex] =\tt \frac{24}{6} = \frac{x}{8} [/tex]
[tex] =\tt 24 \times 8 = 6 \times x[/tex]
[tex] =\tt 192 = 6x[/tex]
[tex] =\tt x = \frac{192}{6} [/tex]
[tex]\hookrightarrow \color{plum}\tt x = 32[/tex]
▪︎Therefore, 32 red roses are there if there are 8 roses.
○=> Solution (9) :Number of children for 2 adults = 7
This can be written in a ratio as 7:2
Number of children in the plaza = 21
Let the number of adults be x.
Which means :
[tex] = \tt \frac{7}{2} = \frac{21}{x} [/tex]
[tex] =\tt7 \times x = 2 \times 21 [/tex]
[tex] =\tt 7x = 42[/tex]
[tex] =\tt x = \frac{42}{7} [/tex]
[tex] \hookrightarrow \color{plum}\tt \: x = 6[/tex]
▪︎Therefore, 6 adults were there in the plaza.
○=> Solution (10) :Cost of 12 pencils = P60
Cost of 1 pencil :
[tex] = \tt \frac{60}{12} [/tex]
[tex] =\tt P5[/tex]
Thus, the cost of one pencil = P5
Cost of 25 pencils :
= Cost of one pencil × 25
[tex] =\tt 5 \times 25[/tex]
[tex] \color{plum}=\tt \: P \: 125[/tex]
▪︎Therefore, the cost of 25 pencils = P125

Find the value of. X in the proportion 5/9=x/36
Answer:
x=20 hope this helps :)
The value of X is 20.
To find this answer, you must first find the least common denominator of both fractions. In this case, the LCD is 36.
Next, you multiply the left side by 4/4. The fraction 4/4 is simply found by dividing the right side denominator (36) by the left side denominator (9). 9 goes into 36 4 times.
5/9 * 4/4 = 20/36.
Thus meaning X = 20. I hope this helps!
