16 = -12 + -7x
Solving
16 = -12 + -7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7x' to each side of the equation.
16 + 7x = -12 + -7x + 7x
Combine like terms: -7x + 7x = 0
16 + 7x = -12 + 0
16 + 7x = -12
Add '-16' to each side of the equation.
16 + -16 + 7x = -12 + -16
Combine like terms: 16 + -16 = 0
0 + 7x = -12 + -16
7x = -12 + -16
Combine like terms: -12 + -16 = -28
7x = -28
Divide each side by '7'.
x = -4
Simplifying
x = -4

Simplify 5 - 2 · 3 + 4.
Using the order of operation you would multiply first so
2 · 3 = 6
5 - 6 + 4 then we would subtract
5 - 6 = -1
-1 + 4 = 3 as your answer.
5−(2)(3)+4=3
Answer: 3
Step-by-step explanation: By using the order of operations,
2 x 3 = 6
5 - 6 = -1
-1 + 4 = 3
Therefore, 3 will be the correct answer for this problem! <3

Answer:
The answer is B x^3
Step-by-step explanation: I just took the FLVS exam and this was the correct answer
x3 is the Greatest Common Factor of x6 and x3.
How do you find the greatest common factor?The greatest common factor is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 shares one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.
What is the GCF of 4 and 6?The largest number of all those common factors is known as the greatest common factor (GCF). Here, 2 is the largest number found in both factors. Hence, the GCF of 4 and 6 is 2.

Since the slope of a vertical line is undefined, is it possible for vertical lines to be parallel.(Explain)
Yes the slope of a vertical line is parallel.
Parallel lines never intersect each other.
Y-axis is a vertical axis cartesian coordinate plane.
All vertical lines would be parallel to y-axis.
Because all vertical lines would have same slope, that is undefined slope.
Therefore, all vertical lines would be parallel lines.
So, we can finally say that it is possible for vertical lines to be parallel.
G.o has 3 orange picks for every two green. If there are 25 picks in all, how many picks are orange
15 picks are orange....
Answer:
15 orange picks.
Step-by-step explanation:
Let x represent the number of orange picks.
We have been given that G.o has 3 orange picks for every two green. We are asked to find the number of orange picks, if there are 25 picks in all.
Since there are 3 orange picks for every two green. so there will be 3 orange picks for all 5 (3+2) picks.
We will use proportions to solve our given problem.
[tex]\frac{x}{25}=\frac{3}{5}[/tex]
Upon multiplying both sides of our equation by 25, we will get:
[tex]\frac{x}{25}*25=\frac{3}{5}*25[/tex]
[tex]x=3*5[/tex]
[tex]x=15[/tex]
Therefore, there are 15 orange picks for all 25 picks.

Julie is digging a square area in her backyard a for a vegtable garden. If the area is 52 square feet, what is the approximate length of one of her garden?
(a) 6 feet
(b) 7 feet
(c) 8 feet
(d) 9 feet
Answer:
The correct option will be: (b) 7 feet.
Step-by-step explanation:
Suppose, the length of the garden is [tex]x[/tex] feet.
As the shape of the garden is like a square, then the area of the garden will be: [tex](length)^2 = x^2[/tex] feet²
Given that, the area is 52 square feet. So, the equation will be.......
[tex]x^2= 52\\ \\ x=\sqrt{52} = 7.211.... \approx 7[/tex]
So, the approximate length of the garden will be 7 feet.
Calculate the slope of the line that passes through the labeled points on the graph.
m=(Y2-Y1)/(X2-X1)
(1.) m=(2-(-1))/(-2-3) = 3/-5 = -3/5
(2.) m=(-2-1)/(-3-2) = -3/-5 = 3/5
(3.) m=Infinity (equation: x=-2)
The slopes of the lines passing through the given points are: 1. [tex]\((-2,2)\)[/tex] and [tex]\((3,-1)\)[/tex]: [tex]\(m = -\frac{3}{5}\)[/tex]. 2. [tex]\((-3,-2)\)[/tex] and [tex]\((2,1)\)[/tex]: [tex]\(m = \frac{3}{5}\)[/tex]. 3. [tex]\((-2,-2)\)[/tex] and [tex]\((-2,3)\)[/tex]: The slope is undefined (vertical line).
To calculate the slope m of a line given two points [tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex], you can use the formula:
[tex]\[m = \frac{y_2 - y_1}{x_2 - x_1}\][/tex]
Let's apply this formula to the given points:
1. For points (-2,2) and (3,-1):
[tex]\[m = \frac{-1 - 2}{3 - (-2)} = \frac{-3}{5}\][/tex]
2. For points (-3,-2) and (2,1):
[tex]\[m = \frac{1 - (-2)}{2 - (-3)} = \frac{3}{5}\][/tex]
3. For points (-2,-2) and (-2,3):
[tex]\[m = \frac{3 - (-2)}{(-2) - (-2)} = \frac{5}{0}\][/tex]
The slope for the third set of points is undefined because the denominator becomes zero, indicating a vertical line. The first two sets of points have slopes of [tex]\(-\frac{3}{5}\)[/tex] and [tex]\(\frac{3}{5}\)[/tex] respectively.

3(2 – 0.9h) (1.3h 4)
If you are solving for "h" here you go.
Simplifying
3(2 + -0.9h) + (-1.3h + -4) = 0
(2 * 3 + -0.9h * 3) + (-1.3h + -4) = 0
(6 + -2.7h) + (-1.3h + -4) = 0
Reorder the terms:
6 + -2.7h + (-4 + -1.3h) = 0
Remove parenthesis around (-4 + -1.3h)
6 + -2.7h + -4 + -1.3h = 0
Reorder the terms:
6 + -4 + -2.7h + -1.3h = 0
Combine like terms: 6 + -4 = 2
2 + -2.7h + -1.3h = 0
Combine like terms: -2.7h + -1.3h = -4h
2 + -4h = 0
Solving
2 + -4h = 0
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Add '-2' to each side of the equation.
2 + -2 + -4h = 0 + -2
Combine like terms: 2 + -2 = 0
0 + -4h = 0 + -2
-4h = 0 + -2
Combine like terms: 0 + -2 = -2
-4h = -2
Divide each side by '-4'.

Nita wants to buy a new keyboard for her computer. She will buy the keyboard when it is on sale for under $50 Write an inequality that describes k, the price in dollars at which Nita will buy the keyboard
This would be k < 50.
This inequality states that k, the price at which Nita wants to buy the new keyboard, is less than 50 dollars.
Answer:
0 ≤ k ≤ 50
Step-by-step explanation:
Here k represents the price of the keyboard ( in dollars ),
Given,
Nita will buy the keyboard,
If the price of the keyboard is under $ 50,
That is, [tex]k \leq 50[/tex]
Also, the price can not be negative,
⇒ [tex]0 \leq k[/tex]
Hence, the required inequality is,
[tex]0 \leq k \leq 50[/tex]
an equation that is true for every value of the variable is a ___
An identical equation is a literal equation that is true for every value of the variable, e.g., the equation (x+1)2=x2+2x+1. A conditional equation (usually referred to simply as an equation) is a literal equation that is not true for all values of the variable, e.g., only the value 2 for x makes true the equation x+3=5.

5x+2(x+9)=x+4x+43
How do you solve this?
x = 25/2
this is your answer
Step 1. Simplify x + 4x + 43 to 5x + 43
5x + 2(x + 9) = 5x + 43
Step 2. Cancel 5x on both sides
2(x + 9) = 43
Step 3. Divide both side by 2
x + 9 = 43/2
Step 4. Subtract 9 from both sides
x = 43/2 - 9
Step 5. Simplify 43/2 - 9 to 25/2
x = 25/2

An engineer designing a ramp in a football stadium was told to keep the slope to a ratio of 1:10. The ramp height is 25 ft. What is the Ideal Mechanical Advantage of the ramp? (Its 10.05, but how do I solve it?)
we know that
To calculate the ideal mechanical advantage for an inclined plane, divide the length of the incline by the height of the incline
Step 1
Find the horizontal distance of the ramp
we know that
the ramp has a slope of [tex]1:10[/tex]
so
by proportion
[tex]\frac{1}{10} \frac{height}{long} =\frac{25}{x} \frac{height}{long} \\ \\x=25*10 \\ \\ x=250\ ft[/tex]
Step 2
Find the length of the incline of the ramp
Applying the Pythagorean Theorem
[tex]incline^{2}=height^{2}+horizontal^{2}[/tex]
substitute the values
[tex]incline^{2}=25^{2}+250^{2}[/tex]
[tex]incline^{2}=63,125[/tex]
[tex]incline=251.25\ ft[/tex]
Step 3
Find the ideal mechanical advantage
[tex]Ideal\ Mechanical\ Advantage=\frac{incline}{height}[/tex]
substitute the values
[tex]Ideal\ Mechanical\ Advantage=\frac{251.25}{25}=10.05[/tex]
therefore
the answer is
the Ideal Mechanical Advantage of the ramp is [tex]10.05[/tex]
