The  simplified equation leads Alex to this conclusion is x=5 or x= 0.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have given few Resultant value.

So, x = 5 shows that the resultant value of x is 5.

and,  x = 0 shows that the resultant value of x is 0.

and, 5 = 5 shows only equality and for equation there must be variable.

and, 5 = - 5 shows only inequality and for equation there must be variable.

Assuming the force is applied horizontally over a flat surface, the net horizontal force is

F (h) = 24 N - 12 N = (10 kg) a

Solve for the acceleration a :

12 N = (10 kg) a

a = 1.2 m/s²

Meanwhile, the net vertical force is zero since the box of only moving horizontally.

F (v) = n - (10 kg) g = 0

where n is the magnitude of the normal force exerted upward by the surface. We see that

n = (10 kg) (9.8 m/s²)

n = 98 N

The friction force has a magnitude that is proportional to the normal force,

12 N = μ (98 N)

where μ is the coefficient of kinetic friction. Solve for μ :

μ = (12 N)/(98 N)

μ ≈ 0.12

Step-by-step explanation:

x = 7

3 + 4x = 5x - 4

3 + 4(7) = 5(7) - 4

3 + 28 = 35 - 4

31 = 31

Option C

The equations having the solutions 7 are 65−2x=6x+9 and 3+4x=5x−4. the correct options are A and C.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that we have to check all the equations having solution 7.

Checking option A,

65−2x=6x+9

65 - ( 2 x 7 ) = ( 6 x 7 ) + 9

51 = 51

Checking option B,

x²+1=8x−5

(7²) + 1 = ( 8 x 7 ) - 5

50≠ 51

Checking option C,

3 + 4x = 5x - 4

3 + 4(7) = 5(7) - 4

3 + 28 = 35 - 4

31 = 31

Checking option D,

9 - x = 14x

9 - 7 = 14 x 7

2≠ 98

Therefore, the equations having the solutions 7 are 65−2x=6x+9 and 3+4x=5x−4. the correct options are A and C.

Answer:

From construction, we construct point M as the center of the figure. According to the linear pair postulate, we know that the sum of the angles on a straight line equal to 180 degrees. Therefore, we know that the other angles have to be 90 degrees. Therefore the angles are congruent because all right angles are congruent.

Answer:

When f(x) = 3x - 3 and g(x) = 2x - 3,

f(3) - g(5) + 12 = 11.

Step-by-step explanation:

Given:

f(x) = 3x - 3

g(x) = 2x - 3

First solve f(3).

f(x) = 3x - 3

Substitute input value.

f(3) = 3(3) - 3

Multiply 3 and 3.

f(3) = 9 - 3

Subtract 3 from 9.

f(3) = 6

Next, solve g(5).

g(x) = 2x - 3

Substitute input value.

g(5) = 2(5) - 3

Multiply 2 and 5.

g(5) = 10 - 3

Subtract 3 from 10.

g(5) = 7

Knowing these values, solve the expression.

f(3) - g(5) + 12

Replace functions with their values.

6 - 7 + 12

Subtract 7 from 6.

(-1) + 12

Add -1 and 12.

429.165

Step-by-step explanation:

I think 1.65 x 260 = 429.165

To solve for 'a' we have to make it the subject of the equation. Since there are two unknowns ('a' & 'b'), we won't get a numerical value of 'a', but an expression in terms of the second unknown 'b'.

Since 2a - b = 4                     [add 'b' to both sides]

then          2a = 4 + b             [divide both sides by 2 = multiplying by  ¹/₂]

                   a = ¹/₂ (4 + b)
