Enter the value for x that makes the equition true. "
3(x - 5) – 3 = 5(x - 2) + 2x
Answer: x = −2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x−5)−3=5(x−2)+2x
(3)(x)+(3)(−5)+−3=(5)(x)+(5)(−2)+2x(Distribute)
3x+−15+−3=5x+−10+2x
(3x)+(−15+−3)=(5x+2x)+(−10)(Combine Like Terms)
3x+−18=7x+−10
3x−18=7x−10
Step 2: Subtract 7x from both sides.
3x−18−7x=7x−10−7x
−4x−18=−10
Step 3: Add 18 to both sides.
−4x−18+18=−10+18
−4x=8
Step 4: Divide both sides by -4.
-4x / -4 = 8 / -4
x = −2

Which represents the solution set to the inequality -1.5(4x + 1) > 4.5 -2.5(x + 1)?
x >-1
x> 7/16
(-∞,-1]
(-∞,7/16]
The solution to the inequality -1.5(4x + 1) > 4.5 -2.5(x + 1) is x > 7/16.
How do we determine the value?Start by simplifying the expressions on both sides of the inequality:
-1.5(4x + 1) = -6x - 1.5
and
4.5 - 2.5(x + 1) = 4.5 - 2.5x - 2.5
Now that the expressions are simplified, substitute them back into the inequality:
-6x - 1.5 > 4.5 - 2.5x - 2.5
Solve for x by adding 2.5x to both sides and subtracting 4.5 from both sides:
-3.5x > 1
0.5x > 1
Finally, divide both sides by 0.5 to get:
x > 2
So the solution set is x > 2.

Plot C(-1,–7), D (6,–7), E(5,3), and F(5,-5) in a coordinate plane. Are CD and EF congruent?
O Yes
O No
(Must show work!!!)
Answer:
No, they are not congruent
Step-by-step explanation:
By CD and EF being congruent, we want to know if they are equal.
What we can simply do here is to find the distance between the points present.
That is, the distance between C and D, the distance between E and F
To get the distances between two points , we use the following equation
D = √(x2-x1)^2 + (y2-y1)^2
For CD, we have
D = √(6 -(-1)^2 + (-7 + 7)^2
D = √(7)^2 = 7 units
For EF, we have
D = √(5-5)^2 + (-5-3)^2
D = √(-8)^2
D = √(64) = 8 units
This clearly shows that they are both not congruent

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
given:
Trey weighs 7 pounds less than his brother.
Together they weigh 119 pounds.
let the weight of Trey's brother is x

what are the solution of the equation 2|×+7|-3=5
Answer:
Solution of the equation 2|x +7|-3=5 is :
x1 = - 11 and x2 = - 3
Answer:
x = -3 and x = -11
Step-by-step explanation:
Find the "bare" absolute value function, then solve the two resulting equations.
2|x+7| -3 = 5
2|x +7| = 8 . . . . . add 3
|x +7| = 4 . . . . . . divide by 2
This resolves to two equations:
x +7 = 4
x = -3 . . . . . subtract 7
and
x +7 = -4
x = -11 . . . . . subtract 7
The two solutions are ...
x = -3 and x = -11

What is the volume of a hemisphere with a radius of 6.1 ft, rounded to the nearest
tenth of a cubic foot?
Answer:
[tex]V_{sm}=475.4\ ft^3[/tex]
Step-by-step explanation:
Hemisphere
It's defined as half of a sphere. The volume of a sphere is:
[tex]\displaystyle V_s=\frac{4}{3}\pi r^3[/tex]
Thus, the volume of a semisphere is half of that:
[tex]\displaystyle V_{sm}=\frac{2}{3}\pi r^3[/tex]
We know the radius is r=6.1 ft, thus:
[tex]\displaystyle V_{sm}=\frac{2}{3}\pi\cdot (6.1)^3[/tex]
[tex]V_{sm}=475.38789\ ft^3[/tex]
Rounded to the nearest tenth:
[tex]\boxed{V_{sm}=475.4\ ft^3}[/tex]

In a video game, players form teams and work together
to earn as many points as possible for their team.
Each team can have between 2 and 4 players.
-
Each player can score up to 20 points in each round of
the game.
Han and three of his friends decided to form a team and
play a round.
Write an expression, an equation, or an inequality for
the number of points Han's team earns in one round if
every player earns a perfect score
Answer:
[tex]20*4[/tex]
Step-by-step explanation:
Han's team has 4 players.
A perfect score is the maximum possible score. Each player can score up to 20 points in each round, so 20 points is the maximum score.
If each of the 4 players scores 20 points, then the total score for the team is:
[tex]20*4[/tex]
That is the expression for the team's points.
Answer: [tex]20*4[/tex]
The expression that represents the number of points that Han's team earns in one round if every player earns a perfect score is 20 × 4.
Maximum point that each player can get = 20
Number of people in Han's team = 4
Therefore, the expression that will represent the number of points that Han's team earns in one round if every player earns a perfect score will then be:
= 20 × 4
= 80
