One number is 3 less than 4 times a second number. The difference of the
first number and twice the second number is 7. What are the two numbers?
Show your work.

Answers

Answer 1

Answer:

the two numbers are 5 and 17

Step-by-step explanation:

4y - 3 = x

x - 2y = 7

to find y:

x - 2y = 7

(4y - 3) - 2y = 7

2y - 3 = 7

2y = 7 + 3

2y = 10

y = 10/2

y = 5

to find x :

4y - 3 = x

4 ( 5 ) - 3 = x

20 - 3 = x

17 = x

The diagonal of a rectangle is 2under root 13cm.If its length and breadth are in the ratio 3:2, then find its area.​

Answers

Answer:

Given :

The diagonal of a rectangle is 2 ✓13 cm.

The length and breadth are in the ratio

3:2.

To find :

The Area of the rectangle.

Solution :

Given that

The ratio of the length and breadth of a rectangle = 3:2

Let they be 3X cm and 2X cm

We know that

The diagonal of a rectangle = √(1²+b³)

units

The diagonal of the rectangle

= √[(3X)³+(2X)³] cm

= √(9x³+4x²) cm

=> √(13X²) cm

=> √13 X cm

According to the given problem

The diagonal of the rectangle = 2√13 cm

=> ✓13 X = 2 √13

=> X = 2√13/√13

=> X = 2 cm

If X = 2 cm then 3X=3(2) = 6 cm

If X = 2 cm then 2X = 2(2)=4 cm

Length = 6 cm

Breadth = 4 cm

We know that

Area of a rectangle = length breadth sq.units

Area of the given rectangle = 6 cm x 4 cm

= 24 cm²

Answers

Answer:

11y+22

Step-by-step explanation:

Answer and Step-by-step explanation:

For this equation, you need to use the distributive property. Before we can solve this, we need to know what the distributive property is. (Important:) The distribute property is where a number is directly outside the parenthesis and is multiplied to each number inside the parenthesis.

With that being said, let's rewrite this expression. Because 11 is outside the parenthesis, multiply it to each of the numbers inside the parenthesis. The numbers 11 x 2 = 22, so:

(y + 2)11 = 11y + 22.

We can remove the parenthesis now that the equation has changed. The reason why the 11 is in front of the y is because it is a coefficient. Coefficients always are written before a variable, which is the y in this case.

So, the answer is 11y + 22.

During, an Experiment, The temperature of a solution changes from 9 4/5 F to 17 1/4 F.
What is the percent of increase in the temperature of the solution?
Enter your answer in the box as a percent rounded to the nearest hundredth

Answers

Using improper fractions, it is found that the percent of increase in the temperature of the solution was of 76.08%.

How to convert improper fractions to standard fractions?

The conversion is made according to the following formula:

[tex]a\frac{b}{c} = a + \frac{b}{c} = \frac{ac + b}{c}[/tex]

In this problem, the initial temperature was given by:

[tex]9\frac{4}{5} = 9 + \frac{4}{5} = 9.8[/tex]

The final temperature was given by:

[tex]17\frac{1}{4} = 17 + \frac{1}{4} = 17.25[/tex]

What is the percent change?

The percent change is given by the change divided by the initial temperature, and multiplied by 100%. Hence:

[tex]C = \frac{17.25 - 9.8}{9.8} \times 100\% = 76.02\%[/tex]

Step-by-step explanation:

Let x represent the number of houses on each street. Normally, Jake delivers 7x papers, and Ryan delivers 3x papers. On the day when Ryan delivered 45 of Jake's papers, we have ...

  (3x +45) > (7x -45)

  90 > 4x . . . . . . . . . . . add 45 -3x to both sides

  22.5 > x . . . . . . . . . . divide by 4

The number of houses on each street will be an integer, so the maximum number of houses on each street is 22.

If Jake normally delivers more than 45 papers, then we must also have ...
