Answers

Answer:

x = x + 7

Step-by-step explanation:

In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.

Solve 7x + 2 =4x+11 please i have 100 points to offer

Answers

Answer:

x=3

Step-by-step explanation:

7x+2=4x+11 ---> subtract 2 to the other side and subtract 4x to the other side

7x-4x=11-2 ---> combine like terms

3x=9 ---> divide by 3

x=3

Answer:

x = 3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

7x + 2 = 4x + 11

Step 2: Solve for x

Subtract 4x on both sides:                    3x + 2 = 11Subtract 2 on both sides:                      3x = 9Divide 3 on both sides:                          x = 3

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    7(3) + 2 = 4(3) + 11Multiply:                               21 + 2 = 12 + 11Add:                                     23 = 23

Here we see that 23 does indeed equal 23.

∴ x = 3 is the solution to the equation.

2.3y+3.2-y=2.1+1.3y+1.1
2/3x+2/3+1/5x=2/3x
20+4r=32-2r

Answers

Answer:

2.3y+3.2-y=2.1+1.3y+1.1

Step-by-step explanation:

The first equation has one solution: z = 0.25.

The second equation has infinitely many solutions.

The third equation has one solution: x = -10/3.

The fourth equation has one solution: r = 2.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

(a) 2.2z+3z=4.5-3.2

Simplifying the left-hand side, we get: 5.2z = 1.3

z = 1.3/5.2 = 0.25

Therefore, the equation has one solution: z = 0.25.

(b)2.3y+3.2-y=2.1+1.3y+1.1

1.3y + 3.2 = 2.2 + 1.3y

Therefore, the equation has infinitely many solutions.

(c) 2/3x+2/3+1/5x=2/3x

Simplifying the left-hand side, we get: 1/5x + 2/3 = 0

1/5x = -2/3

x = -10/3.

(d) 20+4r=32-2r

6r = 12

r = 2

Therefore, the equation has one solution: r = 2.

Hence, The first equation has one solution: z = 0.25.

The second equation has infinitely many solutions.

The third equation has one solution: x = -10/3.

The fourth equation has one solution: r = 2.

Step-by-step explanation:

180-102=78

Answer:

Step-by-step explanation:

first find the final interior angle since we need it to find the exterior

60 + 42 = 102

180 - 102 = 78 degrees

then we just have to do 180 - 78 bc we have a straight line and straight lines are always 180 degrees

180 - 78 = 102 degrees

x = 102

Solve for m: -8 = m/-10 - 16

Answers

Answer:

m = -80

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

-8 = m/-10 - 16

Step 2: Solve for m

Add 16 to both sides:                    8 = m/-10Multiply -10 on both sides:            -80 = mRewrite:                                          m = -80

Answer:

We have this equation:

-8 = m/-10 -1

We can add 8 at both sides:

-8 + 8 = m/-10 -16 + 8

0 = m/-10 -8

Now, we can multiply -8 by -10 with the objective of having the same denominator (-10) in all numbers:

0 = m/-10 - 8*(-10)/-10

0 = m/-10 +80/-10

Now, we can delete all denominators

0 = m + 80

And we can say m = -80

Now, we can replace it to see if it's true:

-80/-10 - 16 = -8, so we know that's true

-80/-10 -16 = 8 - 16 = -8 ..

The ratio of no. of boys to no. of girls in a class is 4:5.Number of boys in class = 12

To find:

Number of girls in class?

Solution:

☯ Let number of girls be x.

Given that,

The ratio of no. of boys to no. of girls in a class is 4:5.

Therefore,

→ 12/x = 4/5

→ x = 12 × 5/4

→ x = 60/4

→ x = 15

∴ Hence, number of girls in a class is 15.

Which of these strategies would eliminate a variable in the system of equations?2x−5y=13
−3x+2y=13
A. Multiply the top equation by 2, multiply the bottom equation by 3, then add the equations.
B. Subtract the bottom equation from the top equation
C. Multiply the top equation by 3, multiply the bottom equation by 2, then add the equations.

Answers

Answer:

We conclude that when we multiply the top equation by 3, multiply the bottom equation by 2, then add the equations, it would eliminate the variable 'x'.

Thus, option (C) is true.

Step-by-step explanation:

Given the system of the equation

2x−5y=13

−3x+2y=13

Multiply the top equation by 3

3(2x−5y) = 3(13)

6x - 15y = 39

Multiply the bottom equation by 2

2(−3x+2y) = 2(13)

-6x + 4y = 26

Adding both equations

6x - 15y = 39

+

-6x + 4y = 26

___________

0x - 11y = 65

-11y = 65               ∵ x variable eliminates

Divide both sides by -11

y = -65/11

Therefore, we conclude that when we multiply the top equation by 3, multiply the bottom equation by 2, then add the equations, it would eliminate the variable 'x'.

Thus, option (C) is true.

The Big Time Band put on a community concert. A total of 1,236 people attended the concert. There were twice as many adults as children who attended the concert. How many adults attended the concert?

Answers

Answer:

412 adults

Step-by-step explanation:

Let the number of adults be x

Let the number of children be y

If a total of 1,236 people attended the concert, then;

x + y = 1236 .....1

If there were twice as many adults as children who attended the concert, then;

y = 2x

Substitute y = 2x into 1

x + 2x = 1236

3x= 1236

x = 1236/3

x = 412

Hence 412 adults attended the concert.
