The tens digit is 3 and the unit digit is 8. So, the number is 38.

Important information:

Let x be the tens digit and y be the unit digit.

The tens digit is 5 less than the unit digit.

[tex]x=y-5[/tex]           ...(i)

The number itself is five more than three times the sum of its digits.

[tex]10x+y=3(x+y)+5[/tex]

[tex]10x+y-3x-3y=5[/tex]

[tex]7x-2y=5[/tex]           ...(ii)

Using (i) and (ii), we get

[tex]7(y-5)-2y=5[/tex]

[tex]7y-35-2y=5[/tex]

[tex]5y=40[/tex]

[tex]y=8[/tex]

Substitute this value in (i).

[tex]x=8-5[/tex]

[tex]x=3[/tex]

Therefore, the number is 38.

Answer:

I believe the answer is p = -7/5

Step-by-step explanation:

Here's the equation and the workthru of my logic:

-5 (p + 3/5) = -4

Divide both sides by -5 to remove the -5 from the left side of the equation,

p + 3/5 = -4/5,

Subtract 3/5 from both sides to solve for p,

p = -4/5-3/5

p = -7/5

Solution is -7/5

92

Step-by-step explanation:

Angle (x+1) is equal to 92 degrees, and x equals 91. If x equals 91, then (x+1) equals 92. (x+1) and angle y are equal angles, so therefore, you can determine that angle y is equal to 92 degrees.

625 is the correct answer :)

Step-by-step explanation:

The newspaper has 625 readers.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

8% = 50 people

Multiply 100/8 on both sides,

100% = 100/8 x 50 people

100% = 625 people

Thus,

There are 625 readers.

Answer:

Step-by-step explanation:

The Perfect Squares  are the squares of the integers

Perfect square trinominal is:   a² ± 2ab + b²  {which is (a±b)²}

So:

The first and third terms must be perfect squares and neither of the perfect  squares can have a minus sign and If the perfect square terms are A2 and B2 then the other term  must be 2AB or -2AB

Answer:

The equation of line is as follows:

Slope-intercept form: [tex]y = 7x-5[/tex]

Standard Form: [tex]-7x+y = -5[/tex]

Step-by-step explanation:

Given that

Slope of line: 7

Point : (1,2)

Slope-intercept form of equation of line is given by:

[tex]y = mx+b[/tex]

Here m is the slope and b is y-intercept.

Putting the value of slope

[tex]y = 7x+b[/tex]

To find the value of b, we have to put the point in the equation

[tex]2 = 7(1) +b\\2 = 7+b\\2-7 = b\\b = -5[/tex]

So the equation will be:

[tex]y=7x-5[/tex]

The standard form of equation of line is:

[tex]Ax+By = C[/tex]

To convert the equation in standard form, subtracting 7x from both sides

[tex]y-7x = 7x-5-7x\\-7x+y = -5[/tex]

Hence, the equation of line is as follows:

Slope-intercept form: [tex]y = 7x-5[/tex]

Standard Form: [tex]-7x+y = -5[/tex]

The equation of a line in slope-intercept and standard form through (1, 2), slope = 7 is  7x - y = 5.

To find the equation of a line in slope-intercept and standard form.

First, we can write the equation in point-slope form. The point-slope formula states:

(y − y₁) = m (x − x₁)

Where m is the slope and

(x1, y1) is a point the line passes through.

Substituting the values from the problem gives:

(y − 2) = 7(x − 1)

Now, we need to convert to standard form.

The standard form of a linear equation is:

Ax + By = C

where, if at all possible,

A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1

We convert as follows:

y − 2 = (7 × x) − (7 × 1)

y − 2 = 7x − 7

−7x + y − 2  = − 7

Adding 2 in both side.

−7x + y − 2 + 2 = − 7 +2

-7x + y = -5

7x - y = 5

Therefore,  the equation of a line in slope-intercept and standard form is 7x - y = 5.

Answer:

x = ± [tex]\sqrt{\frac{a^2b^2-a^2y^2}{b^2} }[/tex]

Step-by-step explanation:

Given

[tex]\frac{x^2}{a^2}[/tex] + [tex]\frac{y^2}{b^2}[/tex] = 1

Multiply through by a²b² to clear the fractions

b²x² + a²y² = a²b² ( subtract a²y² from both sides )

b²x² = a²b² - a²y² ( divide both sides by b² )

x² = [tex]\frac{a^2b^2-a^2y^2}{b^2}[/tex] ( take the square root of both sides )

x = ± [tex]\sqrt{\frac{a^2b^2-a^2y^2}{b^2} }[/tex]

In formula x²/a²+y²/b²=1

Value of  x as subject, x = ± [a√(b² - y²)]/b

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side.

Given equation,

x²/a² + y²/b² = 1

moving y²/b² to right side

x²/a² = 1 - y²/b²

multiplying a² on both sides

a². x²/a² = a². 1 - a². y²/b²

Simplifying

x² = a² - a²y²/b²

x = ± √(a² - a²y²/b²)

x = ± a√(1 - y²/b²)

x = ± [a√(b² - y²)]/b

Hence, value of x = ±[a√(b² - y²)]/b in formula x²/a² + y²/b² = 1
