The difference between two numbers is 9
Find these numbers if their sum is 45.​

Answers

Answer 1

Answer:

spoe that x and y are the two numbers. Then we have x-y=9 and x+y=45. By adding the two equations together we obtain 2x=54 and so x=27. This implies that y=45-27=18.

Ade cycled for 2 hours at an average speed of 15 km/h. Kali travelled the same route as Ade but it took her 2 hour 15 minutes. What is Kali's average speed to 1 dp?

Answers

Answer: 14.0 km/h

Step-by-step explanation:

First find the distance that both Ade and Kali travelled. Use the time and speed of Ade to find this out:

Distance = Speed * Time

= 15 * 2

= 30 km

Kali took 2 hours 15 minutes to travel 30km. Her speed is therefore:

= Distance / Time

Convert the time to decimal:

Mixed fraction = 2¹⁵/₆₀

= 2¹/₄

Decimal = 2.15 hours

Average speed = 30 / 2.15

= 13.95

= 14.0 km/h

Un mester popular a confectionat intru-n an 480 de fluiere,ocarine si viori.Cate instrumente de fiecare fel a confectionat mesterul,stiind ca fluiere si ocarine erau 296,iar ocarine si viori-342?

Answers

Answer:

138 fluiere, 158 ocarine, 184 viori

Step-by-step explanation:

given:

(1) fluiere + ocarine +viori = 480

(2) fluiere + ocarine =296

(3) ocarine + viori =342

din ecuatia (3) avem: viori= 342-ocarine

din ecuatia(2) avem : fluiere= 296-ocarine

in ecuatia (1) inlocuieste ce ai gasit ca sa fie o ecuatie doar cu necunoscuta ocarine: fluiere + ocarine +viori = 480

296-ocarine +ocarine+ 342-ocarine  =480

296+342-480 = ocarine =158

viori = 342-158 = 184

fluiere = 296-158 = 138

Answers

The number 30 represents that the fitness club charges members a separate monthly membership fee of $30.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables

Let f(x) represent the total fee that a person pays for x months of membership. Hence:

f(x) = 30x + 25

Answer:

x=6

Step-by-step explanation:

x+54+5x=90

6x+54=90

6x=36

x=6

Answer:

x=6

Step-by-step explanation:

So, lets go over what we know.

Angle 5x and angle x+54 make up 90 degrees.

We know its 90 degrees since there is a square like symbol on the side of the line.

To sovle for x, we must add the two angles together. This will make them equivelent to 90 degrees.

So:

5x+x+54=90

=

6x+54

Now that we combined our two angles, we can solve it like a normal equation:

6x+54=90

subtract 54 from both sides to get 6x alone:

6x=36

Now divide both sides by 6 so x is alone:

x=6

So now we know that x=6.

If you wan to check your answer, just look at the orginal graph, plug in 8 for x, and see if the two angles add up to 90:

Angle 5x:

5*6

=

30

Angle x+54

6+54

=

60

Add the two angles together:

30+60

=

90

So we have checked and the answer is still correct!

Hope this helps! :D

Rajib wrote the equations y = 8 x minus 2 and y = negative 4 x minus 5. What can Rajib conclude about the solution to this system of equations? The point (2, 14) is a solution to this system of equations. The point (14, 2) is a solution to this system of equations. The point (Negative 4, negative one-fourth) is a solution to this system of equations. The point (Negative one-fourth, negative 4) is a solution to this system of equations.

Answers

Answer:

The point (Negative 4, negative one-fourth) is a solution to this system of equations

Step-by-step explanation:

y = 8x - 2

y = - 4x - 5

y - 8x = - 2 - - (1)

y + 4x = - 5 - - - (2)

Subtract 1 and 2

-8x - 4x = - 2 - (-5)

-8x - 4x = 3

-12x = 3

x = - 1/4

y = 8(-1/4) - 2

y = - 2 - 2

y = - 4

A.24 7/12 sq. inches
B. 24 7/12 cubic inches
C.175/6 sq. inches
D. 175/6 cubic inches

Answers

Answer:

Volume of rectangular prism = 175 / 6 inch³

Step-by-step explanation:

Given:

Base area of rectangular prism = 23 ¹/₃ inch² =  70 / 3 inch²

Height of rectangular prism = 1 ¹/₄ inch = 5 / 4 inch

Find:

Volume of rectangular prism

Computation:

Volume of rectangular prism = Base area of rectangular prism x Height of rectangular prism

Volume of rectangular prism = [70 / 3] x [5 / 4]

Volume of rectangular prism = [350 / 12]

Volume of rectangular prism = 175 / 6 inch³

C.
It will be positive and less than or equal 30.

D.
It will be negative and less than or equal to -30.

Answers

A because it will be positive and greater than 30

Tyson is dividing -30 by a negative integer then the statement C. It will be positive and less than or equal 30 Tyson will get.

What is an integer ?

An integer is a number which has no decimal part.

According to the given question Tyson is dividing -30 by a negative integer.

Let us take the greatest negative integer which is - 1.

Now of e divide (-30/-1) we get 30 which is the quotient.

Now let us take an negative integer which is same as the dividend which will be - 30 it self now if we divide (-30/-30) we get quotient as 1.

So, the least quotient is 1 and the greatest quotient is 30.

∴ In both the cases it is positive and less than or equal to 30.
