Answer:

Step-by-step explanation:

6/9+x=7/10

x=7/10-6/9

when adding fractions both denominators must be equal, we’ll make them 90

x=(7/10)(9/9)-(6/9)(10/10)

x=63/90-60/90

x=3/90, the greatest divisor of 3 and 90 is 3 so divide both the numerator and denominator by 3

x=(3/3)/(90/3)

x=1/30

A group of high school students are volunteering for Habitat for Humanity during their summer break. They
are putting the finishing touches on a house they built. Working alone, Kendra can paint a certain room in 7
hours. Joe can paint the same room in 6 hours. Write an equation that can be used to find how long it will
take them working together to paint the room. How many hours will it take them to paint the room? If
necessary, round your answer to the nearest tenth.

Answers

In response to the question, we may say that It will take Kendra and Joe expression approximately 3.2 hours to paint the room together.

what is expression ?

An expression in mathematics is a collection of representations, numbers, and conglomerates that mimic a statistical correlation or regularity. A real number, a mutable, or a mix of the two can be used as an expression. Mathematical operators include addition, subtraction, fast spread, division, and exponentiation. Expressions are widely used in arithmetic, mathematics, and shape. They are employed in the depiction of mathematical formulas, the solving of equations, and the simplification of mathematical relationships.

Let's denote the time it takes Kendra to paint the room as "K" and the time it takes Joe to paint the room as "J". We can use the formula:

[tex]1/K + 1/J = 1/T\\1/7 + 1/6 = 1/T\\13/42 = 1/T\\13T = 42\\[/tex]

Therefore, T = 42/13 ≈ 3.2 hours (rounded to the nearest tenth).

It will take Kendra and Joe approximately 3.2 hours to paint the room together.

Question 1

A tiling pattern is defined by the pattern rule equation 'n = 6 + 4p`,

where `p is the position number and 'n' is the number of tiles.

How many tiles would there be in position 22?

Answers

Answer:

There would be 94 tiles.

Step-by-step explanation:

The number of tiles is given by the following equation:

[tex]n = 6 + 4p[/tex]

In which p is the current position.

How many tiles would there be in position 22?

This is n when [tex]p = 22[/tex]. So

[tex]n = 6 + 4*22 = 6 + 88 = 94[/tex]

There would be 94 tiles.

The number of titles would there be in the position 22 is 94 titles.

Given that,

A tiling pattern is defined by the pattern rule equation 'n = 6 + 4p.Here p denotes the position number and n denotes the no of titles.

Based on the above information, the calculation is as follows:

n = 6 + 4p

= 6 +  4(22)

= 6 + 88

= 94

Therefore we can conclude that the number of titles would there be in the position 22 is 94 titles.

If 13 candy bars cost $19.76, how much do 20 candy bars cost?

Answers

Answer:

$30.40

Step-by-step explanation:

to find out how much 20 candy bars would cost, first, we have to find out how much 1 candy bar costs. we do this by dividing $19.76 by 13.

$19.76 ÷ 13 = $1.52

so now we know that one candy bar costs $1.52. now, we multiply this value to 20, to know how much 20 candy bars cost. therefore, we get:

20 × $1.52 = $30.40

At Nolan's Car Rentals, customers will pay $60 to rent a mid-sized car for the first day, plus $5 for each additional day. At Westford Rent-a-Car, the price for a mid-sized car is $50 for the first day and $10 for every additional day beyond that. Find the solution to the system.

Answers

Answer:

2, 70

Step-by-step explanation:

It is given that :

At Nolan's Car rentals, if a customer rents a car, he or she has to pay $60 for the car for the first day and more $ 5 for every additional days.

Therefore this gives the equation :

y = 5x +60 ..........(1)

At Westford car rental, the price of the car for first day is $ 50 and additional $10 for every additional day.

So the equation will be :

y = 10x + 50.......(2)

Solving (1) and (2), we get

 5x + 60 = 10x + 50

⇒ 60 - 50 = 10x - 5x

⇒ 10 =  5x

∴ x = 2

Now putting the value of x = 2 in equation (1), we get

y = 5x +60

y = 5(2) +60

y = 70

Therefore, (x, y) = (2, 70)
