Find the missing number so that the equation has no solutions.
?missing number? x+18=5x–12
Answers
Answer:
x=1.5
Step-by-step explanation:
Simplifying
5x + 12 + -1x = 18
Reorder the terms:
12 + 5x + -1x = 18
Combine like terms: 5x + -1x = 4x
12 + 4x = 18
Solving
12 + 4x = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 4x = 18 + -12
Combine like terms: 12 + -12 = 0
0 + 4x = 18 + -12
4x = 18 + -12
Combine like terms: 18 + -12 = 6
4x = 6
Divide each side by '4'.
x = 1.5
Simplifying
x = 1.5
Answer:
Firstly: collect like terms
Secondly: simplify
Lastly: divide the number you got from the one without the letter x by the number you got with the letter x

Tuesday was warmer than monday but colder than wednesday
Wednesday was the warmest day.
As -10° is farther from zero than -3°, Tuesday was colder than Wednesday.

A rectangular shaped parking lot is to have a perimeter of 656 yards if the width must be 82 yards because of a building code what will the length need to be
Answers
The length of the rectangular shaped parking lot will be: 246 yards.
What is the Perimeter of a Rectangular Shape?A rectangular shape has a width and a length. The perimeter of the rectangular shape is simply the sum of all its width and its length. The formula for the perimeter of the rectangular shape would therefore be:
Perimeter = 2(length + width).
Given the following:
Perimeter of the rectangular shaped parking lot = 656 yards
Width of the rectangular shaped parking lot = 82 yards
Length = x = ?
Plug in the values into the perimeter formula for a rectangular shape:
2(x + 82) = 656
Divide both sides by 2
2(x + 82)/2 = 656/2
x + 82 = 328
x + 82 - 82 = 328 - 82
x = 246
Length would need to be 246 yards.

Answers
For the given measures of exterior angle and angles in a triangle , the unknown measure of angle x is equal to 23°.
As given in the question,
In a given triangle,
Measure of exterior angle is equal to 135°
Exterior angle +Adjacent interior angle = 180°
⇒ 135° + Adjacent interior angle = 180°
⇒ Adjacent interior angle = 180° -135°
⇒ Adjacent interior angle = 45°
In a triangle,
Sum of opposite interior angles = Measure of exterior angle
⇒ x° + 112° = 135°
⇒ x° = 135° -112°
⇒ x° = 23°
Therefore, for the given measures of exterior angle and angles in a triangle , the unknown measure of angle x is equal to 23°.

If families consumed apples and granola bars at constant rates, which food had the higher unit rate per hour? Write an equation that represents the rate apples were consumed per minute Write an equation that represents the rate granola bars were consumed per minuteEnter the equation in y=mx format
Answers
Answer:
• Apples: y=1/6x
,• Granola bars: y=1/5x
Explanation:
Apples
First, we calculate the unit rate for the consumption of apples.
Using the points (0,0) and (12,2):
[tex]\begin{gathered} \text{Unit Rate=}\frac{2-0}{12-0} \\ =\frac{2}{12} \\ =\frac{1}{6} \end{gathered}[/tex]Therefore, an equation that represents the rate apples were consumed per minute is:
[tex]y=\frac{1}{6}x[/tex]Granola Bars
We calculate the unit rate for the consumption of granola bars.
Using the points (0,0) and (60,12):
[tex]\begin{gathered} \text{Unit Rate=}\frac{12-0}{60-0} \\ =\frac{12}{60} \\ =\frac{1}{5} \end{gathered}[/tex]Therefore, an equation that represents the rate apples were consumed per minute is:
[tex]y=\frac{1}{5}x[/tex]Which function has the greatest y-intercept?Group of answer choicesf(x)g(x)h(x)All three functions have the same y-intercept.
Answers
Three functions are given. It is required to find the greatest y-intercept of the three functions.
To do this, find the y-intercept of each function and check which of them has the greatest value.
The given equation for f(x) is:
[tex]f(x)=-3x-5[/tex]Notice that this is a linear function in the slope-intercept form, y=mx+c.
Where m is the slope and c is the y-intercept.
Compare to the given equation; it follows that the y-intercept of f(x) is c=-5.
The y-intercept of f(x) is -5.
The graph of g(x) is given.
Recall that the y-intercept is the point where the graph of a function intersects the y axis.
Hence, the y-intercept of g(x) is -3.
The equation for h(x) is:
[tex]h(x)=2\cos\left(2x-\pi\right)+4[/tex]To find the y-intercept, substitute x=0 into the equation:
[tex]\begin{gathered} h(0)=2\cos\left(2(0)-\pi\right)+4 \\ \Rightarrow h(0)=2\cos\left(0-\pi\right)+4=2\cos(-\pi\rparen+4 \\ \Rightarrow h(0)=2(-1)+4=-2+4=2 \end{gathered}[/tex]Hence, the y-intercept of h(x) is 2.
It follows that h(x) has the greatest y-intercept.

Answers
Answer:

b^3 = 125
cube root of b^3 = cube root of 125
the cube root of 125 is 5
-5 is not an equivalent solution (-5)(-5)(-5) =/ (not equal to) 125
so b=5
remember ± means if -5 and 5 are equal to 125, in this case it is not...so its just 5.

The value of b for the expression b³ = 125 is 5.
Option C is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,

Cube root on both sides.
b = ∛125
b = 5
We can not use -5 because.
-5 x -5 x -5 = -125
This is not possible
Thus,
The value of b is 5.

The constant of proportionality that Busy Bee store bottles of fresh jars of honey is 12 hours.
What is the constant of proportionality?The rate at which the fresh jars of honey is stored increases with time. This means that there is a direct proportional relationship between the jars of honey stored and time.
When there is a direct proportion, the two variables move in the same direction. As time increases, the jars of honey stored increases.
The equation that is used to represent direct proportion is:
y = bx
Where:
y = dependent variable = jars of honey stored b = constant of proportionality x = independent variable = number of hours36 = b3
