Answer:

x = -0.8

Step-by-step explanation:

2.35+0.25x = 1.75+0.4

To find x, we must first isolate the value.

This is done by subtracting any values on the same side as the x.

Thus, we subtract 2.35 from both sides.

We are now left with the following:

0.25x=1.75+0.4-2.35

Now you should simplify the right side by finding the sum, which is -0.2, so:

0.25x=-0.2

Finally, solve by dividing each side by 0.25.

x = -0.8

Answer:

[tex]x = -\dfrac{4}{5} \ \ \textrm{or} \ \ x = -0.8[/tex]

Step-by-step explanation:

First, multiply both sides by 100 to make the numbers nicer to work with.

[tex](100)(2.35 + 0.25x) = (1.75 + 0.40)(100)[/tex]

[tex]235+25x=175+40[/tex]

Next, isolate x by moving all the constant terms to one side and then dividing by x's coefficient.

[tex]25x=175+40-235[/tex]

[tex]25x = -20\\\overline{\, \, 25 \, \,} \: \, \, \, \, \, \, \, \overline{ \,\, 25 \, \,}[/tex]

[tex]x = -\dfrac{20}{25}[/tex]

[tex]x = -\dfrac{4}{5}[/tex]

So, the value of x is -4/5 or 0.8.

Answer: [tex]x = 34[/tex]

Step-by-step explanation:

Let x be the original amount of Pokémon cards Tommy had, we know that he sold half of them; this can be express as:

                                                              [tex]\frac{x}{2}[/tex]

After this he changed his mind and bought 17 cards, then he has:

                                                         [tex]\frac{x}{2} + 17\\[/tex]

We know that he has 34, then we have the equation:

                                                       [tex]\frac{x}{2} + 17 = 34[/tex]

Solving for x we have:

                                                        [tex]\frac{x}{2} + 17 = 34[/tex]

                                                        [tex]\frac{x}{2} = 34 - 17[/tex]

                                                            [tex]\frac{x}{2} = 17[/tex]

                                                         [tex]x = (2)(17)[/tex]

                                                            [tex]x = 34[/tex]

By simplifying the expression (-4-√7)² we get the value as 23+8√7 in decimals we get 44.12.

Given that,

The expression is (-4-√7)²

We need to find the value and simplify the expression.

Take the expression.

(-4-√7)²

We know that (a+b)²=a²+2ab+b²

The expression is in the form of (a+b)² substitute the formula.

(-4)²+2(-4)(-√7)+(-√7)²

Now do the square

16+2(-4)(-√7)+7

Now do the multiplication.

16+8√7+7

Now do the addition.

23+8√7

We can write the √7 value

23+8(2.64)

Multiply 8 and 2.64

23+ 21.12

Now adding

44.12

Therefore, By simplifying the expression (-4-√7)² we get the value as 23+8√7 in decimals we get 44.12.

The required measure of the angle measured by using a protractor is 70°

Given situation : A protractor is used on an angle

A ray is passed through this angle

we have to find the measure of the total angle

Let the angle is passed through an angle ∠ABC

and the ray be BD

thus the two angles which will be formed will be

∠ABD and ∠DBC

Now let one of the angles , say angle ∠ABD be 13°

and ∠DBC be 57°

Thus the whole angle would be ∠ABD + ∠DBC = ∠ABC

∠ABC = 57 + 13 = 70°

Thus the required measure of the angle is 70°

Linear equations are described for strains withinside the coordinate system. If an equation has  homogeneous variables of diploma 1 (that is, best one variable), the equation is stated to be a linear equation in a single variable. A linear equation may have more than one variables. When linear equations have  variables, they may be known as bivariate linear equations.

Examples of linear equations are 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x - y + z = 3. This article gives definitions of linear equations, preferred types of linear equations in a single, , and 3 variables,  and  examples of them with complete explanations.

Let x=the smaller part

Step-by-step explanation:

The image of the point (0, -4) after the transformation T3,3 R270 is (3, 1).

The image of the given point after transformation considers the given point is P(0, -4)

Rules of transformation R(27°,0)° T<3, 3> representing translation T<3, 3> after that rotate 270 degrees counter-clockwise If a figure translated by T<3, 3>

( x,y)= (( x + 3), ( y + 3))

p (0, -4) = p' (( 0 + 3), ( -4 + 3))  

p (0, -4) = p'(3, -1)

When rotating a point 270 degrees counter-clockwise about the origin our point

p'(x,y) becomes p''(y,-x)

p'(3, -1) = p''(3, -(-1))

p'(-10,2) =p"(3, 1)

Therefore, the image of the point (0, -4) after the transformation T3,3 R270 is (3, 1).

Answer:

Step-by-step explanation:

The slope of the perpendicular line is 1/5

The equation of the line is given as

5x + y = -4

The equation of a line can be represented as

y = mx + c

Where

Slope = m

So, the first step is to make the variable y the subject in 5x + y = -4

This gives

y = -5x - 4

By comparing the equations, we have the following

m = -5

This means that the slope of 5x + y = -4 is -5

So, we have

Slope 1 = -5

The slopes of perpendicular lines are opposite reciprocals

i.e.

Slope 2 = -1/Slope 1

This gives

Slope 2 = -1/-5

Evaluate

Slope 2 = 1/5

Hence, the perpendicular line has a slope of 1/5

Answer: 5x^3 + 4x^2 – (6x^2 – 2x – 9) =

5x^3 + 4x^2 – 6x^2 + 2x + 9 =

5x^3 – 2x^2 + 2x + 9

Step-by-step explanation: We have to find the difference (5x^3 + 4x^2) - (6x^2 - 2x - 9)

On distributing the minus over the parenthesis, we get

5x^3 + 4x^2 - 6x^2 + 2x + 9

Now, we group the like terms and combine them

5x^3 + (4x^2 - 6x^2) + 2x + 9

The probability of x being equal o 19.62 is d) 0.

It is given that x is normally distributed with a mean of 12 and a standard deviation of 3.

Now, Normal distribution is a continuous distribution.

This implies that the probability is measured over an interval, taking an infinite number of points in between.

If we plot a continuous distribution, the probability here at a point is not the value of the y coordinate at that point. Instead, it is seen as an area under the curve of the distribution, between the two intervals, say a and b.

Therefore, if we take up a single point say c, then the probability will be the area under the curve from c to c, which will obviously be 0.

Hence, the probability that x = 19.62 will be 0.
