the equation is 7x-3 over 9 > 8-2x
Answer:
solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]
First we will solve the inequality to find value of x
Solving:
[tex]\frac{7x-3}{9}\geq 8-2x[/tex]
Step 1: Multiply both sides by 9
[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]
Step 2: Adding 3 on both sides
[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]
Step 3: Add 18x on both sides
[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]
Step 4: Divide both sides by 25
[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]
So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.

Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20

If you solve the inequalty 2x < 14, the solution set is x < 7. Graph x < 7 on a number line. Which one of the listed values of x is included in x < 7
A) x=8
B) x = 7
C) x = 12
D) x= -8
Answer:
D) x = -8
Step-by-step explanation:
All the values less than 7 are included in the number line. The graph on number line is shown in figure attached. In the options given, all values in Option A, B and C are greater than 7 so these cannot be included.
4) Which pair of triangles is congruent by Angle - Angle- Side?
We want to see which pair of triangles is equivalent by the Angle-Angle-Side criteria.
The correct option is 2, where we have two equal angles, and the bottom side is equal in both triangles.
The Angle-Angle-Side criteria means that if two triangles have an equal side, and the two correspondent angles also are equal, then these triangles are equivalent.
So we just need to see (by notation, not by how the triangles look like) in which ones we have two equal angles and one equal side.
That one is the second pair of triangles.
We can see that the two top angles are equal (two curves) and that the left angle in the left triangle is equal to the right angle on the other triangle (so we have two equal angles).
Also, the bottom side is equal on both triangles.
Then the angle-angle-side criteria is meet, meaning that these two triangles are equivalent.

Matt can walk 500 m from his home on King Street, and then 900m along Queen Street to go to his school. He can also walk across a diagonally across a park from his home to his school. Assuming King Street and Queen Street meet at right angles, how far does he walk across the park to go to school?
Answer:
He walks 1030 meters if he walks across the park.
Step-by-step explanation:
In order to solve this question we will need to know that [tex]c^{2} = a^{2} + b^{2}[/tex] (were c is the length of the hypotenuse (the diagonal line) of a right angle triangle, and a and b are the legs (the sides that form a right angle). So them means that.....
Let "c" be the distance he will need to walk if he was going to go through the park
Let "a" be the distance he walks on King Street
Let "b " be the distance he walks on Queen Street, then.....
[tex]c^{2} = a^{2} + b^{2}[/tex]
[tex]c = \sqrt{a^{2} + b^{2} }[/tex]
(Now plug in the values of a and b and get.....)
c = [tex]\sqrt{500^{2} + 900^{2} }[/tex]
c = [tex]\sqrt{1060000 }[/tex]
c = 1029.563014............
So I would assume that you have to round to the nearest meter. And as a result we get 1030 meter.
what is the coefficient of -2x+8=10
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+8=10
Step 1: Subtract 8 from both sides.
−2x+8−8=10−8
−2x=2
Step 2: Divide both sides by -2.
−2x−2=2−2
x=−1
Answer:
Answer:
-2
Step-by-step explanation:
The coefficient of an equation or expression is any constant that precedes a variable. So, in this case, the only variable is x, so the coefficient is the preceding number, -2.

Answer:
7 [tex]\frac{1}{2}[/tex] miles
Step-by-step explanation:
The problem above is under the topic, "Subtracting Mixed Numbers with Similar Fractions."
In order to find the answer, you have to subtract the whole number parts first.
12-5 = 7
Then, you have to subtract the fractional parts. All you have to do is to get the difference of the numerators and copy the denominator.
7/8 - 3/8 = [tex]\frac{4}{8}[/tex]
Therefore, 12 [tex]\frac{7}{8}[/tex] - 5 [tex]\frac{3}{8}[/tex] = 7 [tex]\frac{4}{8}[/tex] miles
Let's simplify: 7 [tex]\frac{1}{2}[/tex] miles
David biked 7 [tex]\frac{1}{2}[/tex] miles farther on Tuesday than on Wednesday.

How many hours until the charges for each company will be equal and what is that charge
Answer:
25 hours, charge= 800
Step-by-step explanation:
300 + 20x = 500 + 12x
8x = 200
x = 25
300 + 20(25)
300+500 = 800
500 + 12(25)
500 + 300 = 800

Identify the domain of the function.
Answer:
Step-by-step explanation:
domain represents the numbers at the x endpoints of a graph.
on the graph we see that on the left, the line ends when x is -4
on the right, the line ends when x is 4
the domain is
-4, 4
but notice how on the left there is an open circle
this will be written with a parentheses
( -4, 4
and notice how on the right there is a closed circle
this will be written with a bracket
(-4, 4]
so the answer is C
Solve 4x + 8y = 16 for x.
O A. x=-8y + 4
O B. x= -2y+ 16
O C. x= -2y+ 4
D. X = 8y + 16
4x + 8y = 16
4x = 16 - 8y
4x = 4 (4 - 2y)
x = 4( 4 - 2y)/4
X = 4 - 2y
X = -2y + 4

Need help ASAP!! Will mark brainliest
Answer:
The answer is D-16
Step-by-step explanation:
Since we have x on one side, and 49 degrees on the other, both angles are the same, so we subtract 1 from 49 to get 48, so that 3x has to equal 48. So we just divide 48 by 3 to get 16, so x = 16.
