5x-7=2x+8 solve for x

Answers

Answer 1

Answer:

x=5

Step-by-step explanation:

Simplifying 5x + -7 = 2x + 8 Reorder the terms: -7 + 5x = 2x + 8 Reorder the terms: -7 + 5x = 8 + 2x Solving -7 + 5x = 8 + 2x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. -7 + 5x + -2x = 8 + 2x + -2x Combine like terms: 5x + -2x = 3x -7 + 3x = 8 + 2x + -2x Combine like terms: 2x + -2x = 0 -7 + 3x = 8 + 0 -7 + 3x = 8 Add '7' to each side of the equation. -7 + 7 + 3x = 8 + 7 Combine like terms: -7 + 7 = 0 0 + 3x = 8 + 7 3x = 8 + 7 Combine like terms: 8 + 7 = 15 3x = 15 Divide each side by '3'. x = 5 Simplifying x = 5

Answer 2
5x-7=2x+8
5x-2x=8+7
3x=15
x=5

The number of players the team can bring to the tournament is 13.

The first step is to determine the total budget for all the players. To do this, subtract the cost of renting the bus from the total money raised.

Budget for all the players = $1158.25 - $836.50 = $321.75

The second step is to determine the number of players that can go for the tournament, divide the total budget by the budget per player.

Number of players that can attend the tournament = $321.75 / $24.75 = 13 players.

Normal curve A has a wider distribution than Normal curve B. The distribution A must has ____________.

A. a smaller mean
B. a larger standard deviation
C. a smaller standard deviation
D. a larger mean

Answers

The correct answer is C

The distribution A must has a smaller standard deviation. So, option C is correct.

What does "normal" describe in statistics?

Normal usually refers to the word "normal" in normal distribution.

The normal distribution is somewhat similar where the main observation (mean or its surrounding) occurs frequently and as we go far from mean, its chances decrease.

If we've got a normal distribution, then we can convert it to a standard normal distribution and its values will give us the z score.

If we have

[tex]X \sim N(\mu, \sigma)[/tex]

(X is following a normal distribution with mean and standard deviation )

then it can be converted to a standard normal distribution as

[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]

Normal curve A has a wider distribution than Normal curve B.

The distribution A must has a smaller standard deviation.

Solving number 29

1/2m(10 + 6m) - 1/5m(10m+10)

(Trust me, it looks harder than it really is)

1/2m(10 + 6m) - 1/5m(10m+10)

So first we need to simplify this problem...

In the figure below, m 110°, m 68°, and KN bisects LKM. Find JKN.

Answers

Answer:

m<JKN=76º

Step-by-step explanation:

since the angle bisects just divide 68 by 2

m<LKN=34º

then since JKM is the total of all angle measurements

110-68=42

so m<JKL=42º

JKL+LKN=JKN

42+34=76

to check just add the measurements and makes sure that they make 110

so 76+34=110

The value of an angle ∠JKN will be 76 degrees.

What is an angle?

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet. In geometry, the ray, line, or segment that divides a given angle into two equal pieces is known as the angle bisector.

Given that In the figure, m 110°, m 68°, and KN bisects LKM.

Since the angle bisects just divide 68 by 2

∠LKN=34º

Then since JKM is the total of all angle measurements

110-68=42

∠JKL=42º

JKL+LKN=JKN

42+34=76 degrees

Therefore, the value of an angle ∠JKN will be 76 degrees.

The answer is the opposite of 104°.  The negative inverse of 104° is -104° I think.

HGI is -140°.

EFG is 140°.

Gotcha!
Answer & Explanation:
Angles EGF And HGI are congruent to each other, Which means if EGF is 104 degrees then HGI is 104.
1. The size of HGI is 104 degrees


Angle EGF is 104 degrees, and we are looking to find the size of EFG,
So since E to F is a straight line, we are going to add 104(EGF) to 180, and we have 284.

2. The size of EGF is 284 degrees.


Define:
Congruent: Triangles that have both the same shape and the same size.
Straight line= 180degrees
Scalene triangle: A triangle that has no equal sides.
Isosceles Triangle: a triangle that has two sides the same length.
Equilateral triangle: A triangles all three sides are congruent.

Step-by-steThe graph represents the heights of two climbers on a climbing wall over a 12-minute time period.

A graph titled The Climbing Wall where the horizontal axis shows time (minutes), numbered 1 to 12, and the vertical axis shows height (feet) numbered 2 to 24. The line labeled Brynn's climb begins at 0 feet in 0 minutes, to 15 feet from 5 to 7 minutes, to 0 feet in 10 minutes. The line labeled Abby's climb begins at 4 feet in 0 minutes, to 14 feet from 4 to 6 minutes, to 22 feet in 8 minutes, to 0 feet in 12 minutes.

Which statement is true about the climbers’ heights?

Brynn was resting at a constant climbing height when Abby’s climbing height was decreasing.

Abby’s climbing height was decreasing when Brynn’s climbing height was increasing.

The heights of both climbers increased, then decreased, with no rest at a constant height.

Both climbers rested on the wall at a constant height for 2 minutes.p explanation:

Fourth option is true, because both climbers had a 2-minute rest.

correct choice is D.

What is a graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter. Each object in a graph is called a node.

The graph represents the heights of two climbers on a climbing wall over a 12-minute time period.

Consider each graph separately.

Brynn's graph: The height was increasing from the start to the 5th minute. Then Brynn was resting 2 minutes at a constant climbing height, then the   height was decreasing from the 7th minute to the 10th minute.

Abby's graph: The height was increasing from the start to the 4th minute. Then Abby was resting 2 minutes at a constant climbing height, then the   height was again increasing from the 6th minute to the 8th minute and then the height was decreasing from the 8th minute to the 12th minute.

First option is false, because actually Abby was resting from 4th to 6th minutes and from 4th to 5th minute Brynn was still climbing.

Second option is false, because Abby’s climbing height starts decreasing later than Brynn's climbing height starts.

Third option is false, because both Brynn and Abby has a rest.

Fourth option is true, because both climbers had a 2-minute rest.

correct choice is D.
