[tex] x = \frac{1}{10} , y = \frac{83}{10} [/tex]

Step-by-step explanation:

y=53x+3

y=73x+1

Solve y = 53x + 3 for equ 2 | equ means equation

[tex] \sf \: 53x + 3 = 73x + 1[/tex]

Substract 73x from both sides

[tex] \sf \: 53x - 73x + 3 = 1[/tex]

Solve 53x - 73x

[tex] \sf - 20x + 3 = 1[/tex]

Substract 3 from both sides

[tex] \sf - 20x + 3 - 3 = 1 - 3[/tex]

Solve

[tex] \sf \: - 20x = - 2[/tex]

Divide both sides by -20

[tex] \sf \frac{- 20x}{ - 20}= \frac{ - 2}{ - 20} [/tex]

Solve

[tex] \sf x = \frac{1}{10} [/tex]

[tex] \sf ------------------------------------------------- [/tex]

Substitute x = 1/10 into equ 1

[tex] \sf y = 53x + 3[/tex]

Insert x = 1/10

[tex] \sf y = 53( \frac{1}{10} ) + 3[/tex]

multiply 54 by the numerator which is 1

[tex] \sf \: y = \frac{53}{10} + 3[/tex]

Turn 3 to 3/1

[tex] \sf \: y = \frac{53}{10} + \frac{3}{1} [/tex]

L.C.M = 10

[tex] \sf y = \frac{ \frac{53}{10} \times 10 \: + \: \frac{3}{1} \times 10 }{10} [/tex]

The number of hours Bruce spent doing homework last week if he spent 1/5 of Darell's time is 1 hour.

Time Darell spent doing homework last week = 5 hours

Time Bruce spent doing homework last week = 1/5 of Darell's time

= 1/5 of 5

= 1/5 × 5

= (1 × 5) / (5 × 1)

= 5/5

= 1 hour

In conclusion, given the fraction of time Bruce spent doing homework last week, that means, he spent 1 hour doing homework.

Answer :

The shaded region composed of triangle and square has an area of 28 in²

An equation is an expression relating two or more numbers and variables.

The area of a rectangle is the amount of space occupied by the rectangle. It is given by:

Area = length * width

From the diagram:

Area of rectangle = length * width = 8 in * 5 in = 40 in²

Area of triangle = (1/2) * base * height = (1/2) * 8 in * 3 in = 12 in²

Area of shaded region = Area of rectangle - Area of triangle = 40 in² - 12 in² = 28 in²

The length of the hypotenuse of a 45 45 90 triangle with one side of length 8 is 8√2.

The length of the hypotenuse of a 45 45 90 triangle can be calculated using the Pythagorean Theorem. The Pythagorean Theorem states that the sum of the squares of the two sides of a right triangle is equal to the square of the hypotenuse. This can be expressed mathematically as a2 + b2 = c2, where a and b represent the lengths of the two sides and c represents the length of the hypotenuse.

In a 45 45 90 triangle, both sides are equal in length. This means that the mathematical equation simplifies to a2 + a2 = c2 or 2a2 = c2. To calculate the length of the hypotenuse, we can solve for c by taking the  square root of both sides, resulting in c = √2a.

In this particular example, if the length of one of the sides is 8, then the length of the hypotenuse can be calculated as c = √2(8) = 8√2. Therefore, the length of the hypotenuse of a 45 45 90 triangle with one side of length 8 is 8√2.

From linear equation of a line,

y=mx+c or y=mx+b

Slope of a line is m and y-intercept is c (or b).

So first we have to make y the subject in

→8x+y=9

→y= - 8x+9

y = mx + c

Hence slope is (-8) and y-intercept is 9.

for x-intercept, put y=0 and we get

0 = -8x+9

x=-8/-9

x= 8/9

therefore x intercept is 8/9.

The equation of variation is xy = k.

The required values are given below.

A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.

Given:

y inversely varies as x.

That means, y ∝ 1/x.

So, y = kx, where k constant of variation.

Then, x × y = k

When y = 8, x = 3.

k = 3 × 8 = 24

So, the equation of variation is xy = 24.

When x = 6,

6y = 24

⇒ y = 4

When y = 9, x = 6.

k = 6 × 9 = 54

So, the equation of variation is xy = 54.

When y = 4,

4x = 54

⇒ x = 27/2

When y = 1.5, x = 14.

k = 1.5 × 14 = 21

So, the equation of variation is xy = 21.

When x = 9,

9y = 21

⇒ y = 7/3

When y = 20, x = 10.

k = 20 × 10 = 200

So, the equation of variation is xy = 200.

When y = 25,

25x = 200

⇒ x = 8

Therefore, the values are given above.

When a number greater than 1 is written in scientific notation, the exponent is positive.

Scientific notation is a way of expressing numbers that are very large or very small using a decimal number between 1 and 10, multiplied by a power of 10. For example, instead of writing the number 100,000,000 as 100,000,000, it can be written in scientific notation as 1 x 10^8.

The exponent of a number in scientific notation is the power of 10 that the decimal number is multiplied by, and it gives the number of places the decimal point is moved to the right or left to obtain the original number. In the example above, the exponent is 8, which indicates that the decimal point has been moved 8 places to the right to get the original number 100,000,000.

When the number is greater than 1, the exponent of scientific notation is positive and indicates that the decimal point is moved to the right.

Brad takes 6 minutes to run a mile assuming he can maintain the same pace.

Given that,

One lap around the inside lane of a standard track = 400m

Time taken for Brad to jog one lap around a track = 1 minute and 30 secs

We know that one mile = 1609.34 meters = 1600 meters (approximately)

Since Brad can jog 400m in 1 minute and 30 secs

1600 meters = 400*4 meters

Assuming that he can maintain the same pace:

so, the total time taken to run 1 mile = 1 minute 30 secs * 4 = 6 minutes

Hence, Brad takes 6 minutes to run a mile assuming he can maintain the same pace.

We must remember to multiply each integer by a power of 10 while subtracting numbers in scientific notation.

A value's accuracy is influenced by the number of significant digits in the value, which is frequently a measurement. Count the significant digits starting with the first non-zero digit. All zeros are permitted in the decimal places to the right of the last non-zero place. Consider the five significant digits in the number 0.0079800. Any zeros to the right of the last non-zero digit, when they come from the measurement, are significant. rounding an integer to 3 significant digits and 3 decimal places is identical. Go up to three and begin counting at the first digit that is not zero. Remove the last digit after that. The final two digits to the right of the decimal point should be increased by zeros.

To make it simple to subtract these integers, they must all be in the same power, as demonstrated in the example below.

5×10^2−3×10^2=

5(100)−3(100)^2×10^2=

Answer:

-2

Step-by-step explanation:

Let's call the unknown number x.

We are given that:

1/x + 15 = 13

To find the value of x, we need to isolate x on one side of the equation.

To do this, we can subtract 15 from both sides:

1/x + 15 - 15 = 13 - 15

This gives us:

1/x = -2

To find x, we can multiply both sides by x:

x * (1/x) = x * (-2)

This gives us:

x = -2x

Therefore the number is -2

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important.

Similar to a set, it has members (also called elements, or terms).

The length of the series is the number of elements (potentially infinite). In contrast to a set, the same items might appear more than once in a sequence at various points, and unlike a set, the order is important.

A sequence can be described formally as a function from natural numbers (the positions of the sequence's elements) to the items at each of those positions.

An indexed family, which is a function from any index set, can be thought of as a generalization of the idea of a sequence.
