Answer: P=2L+2w

Step-by-step explanation:

P=perimeter.

P=2L+2w ==> there are two lengths and two widths in a rectangle. That totals to 4 sides in a rectangle.

The linear equation is

x=33

A linear equation in one variable is defined as an equation with only one variable. The standard form of linear equation in one variable is stated as Ax + B = 0, where A and B can be any two numbers, and x has just one possible value.

36- x=3

x=33

The coefficients can be considered as parameters of the equation, and may be arbitrary expressions, supplied they do no longer incorporate any of the variables. To yield a significant equation, the coefficients required to now not all be 0.

alternatively, a linear equation can be obtained by using equating to zero a linear polynomial over a few area, from which the coefficients are taken.

The answers of such an equation are the values that, whilst substituted for the unknowns, make the equality true.

Answer:

28 nickels and 17 dimes

Step-by-step explanation:

A nickel is worth 5 cents and a dime is worth 10 cents

If there are X nickels and Y dimes

Total value = 5X + 10Y cents

$3.10 == 3.10 x 100 = 310 cents

So 5X + 10 Y = 310

Divide both sides by 5 to get

5X/5 + 10Y/5 = 310/5

X + 2Y = 62  (1)

The total number of coins is X + Y and is given to be 45

X + Y = 45    (2)

Subtract Eq(2) from Eq(1) to get

X + 2Y - (X + Y) = 62-45 = 17

X + 2Y - X - Y = 17

Collecting like terms

(X - X) + (2Y - Y) = 17

Y = 17

So number of dimes = 17

To find X, the number of nickels use equation (2)

X + 17 = 45

Subtract 17 from both sides

X + 17 - 17 = 45 - 17

X = 28

So number of nickels = 28

For the given value of angle;

∠A = 62°

The complement of ∠A is; 90 - ∠A

complement = 90 - 62

complement = 28°

Now, for supplementary angle:

For the given: ∠A = 62°

supplementary = 180 - 62

supplementary = 118°

Thus, the complement and supplement are obtained as 28° and 118°.

Answer:

B

Step-by-step explanation:

None of the provided options are irrational. Irrational numbers are those which cannot be expressed as the ratio of two integers. In other words, if represented in decimal form, they would continue indefinitely after the decimal point, such as the value of π. This also means, by definition, they cannot be both irrational and an integer.

They are all real numbers as they can represent a distance along a line (they could all be plotted on a number line or graph, for instance).

Only 0 and 4 out of the provided options are integers (whole numbers). As mentioned above, all integers are rational by definition.

The measures of the angles are x = 40, x = 110 and y = 70

Angles are formed when two or more lines intersect

The figure represents the given parameters

On the figure, we have the following highlights

Angle 3 and angle y are corresponding angles.

Corresponding angles are congruent

So, we have

y = Angle 3

From the figure

Angle 3 = 70

So, we have

y = 70

The angle on a straight line is 180 degrees

So, we have

x + y = 180

This gives

x + 70 = 180

Evaluate the like terms

x = 110

The triangle is an isosceles triangle.

So, we have

y = Angle 2

This means that

Angle 2 = 70

The sum of angles in a triangle is 180

So, we have

z + y + Angle 2 = 180

This gives

z + 70 + 70 = 180

Evaluate

z = 40

Hence, the measures of the angles are x = 40, x = 110 and y = 70

Answer:

Step-by-step explanation:

The third term of the geometric progression will be 1 / 27 with common ratio 2 / 3.

We are given that:

2nd term of geometric progression = 1 / 18

5th term = 4 / 243

Now, we can also write it as:

2nd term = a r ( where r is the common ratio and a is the initial term.)

a r = 1 / 18

5th term = a r⁴

a r⁴ = 4 / 243

Now divide 5th term by 2nd term, we get that:

a r⁴ / a r = ( 4 / 243 ) / ( 1 / 18 )

r³ = 72 / 243

r³ = 8 / 27

r = ∛ (8 / 27)

r = 2 / 3

3rd term = a r²

a r² = a r × r

= 1 / 18 × 2 / 3

3rd term = 1 / 27

Therefore, the third term of the geometric progression will be 1 / 27 with common ratio 2 / 3.

The equation of a line that is parallel to y = 4x - 7 and goes through the point (4,1) is y = 4x - 15.

Given line: y = 4x - 7

Slope of line m₁ = 4

Two lines are parallel lines when the slopes of the lines are the same.

so, m₁ = m₂

m₂ = 4

Now, the equation of a line with slope 4 and passing through the point (4,1) is:

⇒ y - y₁ = m (x - x₁)

⇒ y - 1 = 4(x - 4)

⇒ y - 1 = 4x -16

⇒ y = 4x - 15

Hence the equation of a line that is parallel to y = 4x - 7 and goes through the point (4,1) is y = 4x - 15.

Answer:

Step-by-step explanation:

You want to find the number of dimes (x) and the number of quarters (y) in 19 coins that have a total value of $3.55.

Using the given variables, we can write two equations. One is for the number of coins; the other is for their value.

  x + y = 19 . . . . . . . . . . . number of coins

  10x +25y = 355 . . . . . value in cents

It usually works well to solve an equation involving the highest-value coin. That means we want to eliminate the x-variable. Using the first equation, we can write ...

  x = 19 -y

Substituting into the second equation, we get ...

  10(19 -y) +25y = 355

  190 +15y = 355 . . . simplify

  15y = 165 . . . . . . . subtract 190

  y = 11 . . . . . . . . . . divide by 15

  x = 19 -11 = 8

The number of dimes is 8.

The number of quarters is 11.

__

Alternate solution

The average coin value is 355/19 = 18 13/19 cents. The proportion of the highest-value coins is the ratio of the difference between this value and the lowest value, divided by the difference in values.

  proportion of quarters = (18 13/19 -10)/(25 -10) = (8 13/19)/15 = (165/19)/15

  proportion of quarters = 11/19

Multiplying this by the number of coins (19) gives the number of quarters:

  (11/19)×19 = 11 . . . . quarters

You may recognize some similarities to the above solution.

The inverse of multiplication is division. If three groups of four add up to twelve, twelve divided into three equal groups adds up to four in each group. The basic purpose of splitting is to determine how many equal groups have been formed or how many people are in each group when equitably sharing.

To divide two numbers, use the formula Dividend Divisor = Quotient + Remainder. The dividend seems to be the number being divided in this case. The number that divides the number (dividend) into equally equal parts is known as the divisor.:
