Write 5 ratio equivalent to 9:13?

Answer:

=PxTxR/100

=12000x5x2/100

=1200

Answer:

1) x= -3

  y= 4

2)

  x= 1

  y= -4

Step-by-step explanation:

1)

-4x+3(3x+13)=24

-4x+9x+39=24

5x+39=24

   -39.  -39

5x=-15

/5.    /5

x= -3

Now fill in X to find y

y=3(-3)+13

y=-9+13

y=4

2)

-4x+3(3x-7)=-16

-4x+9x-21= -16

5x-21 = -16

   +21.   +21

5x=5

/5. /5

x=1

3(1)-7=y

3-7=y

-4=y

Answer:

$8

Was the original price.

Step-by-step explanation:

100% - 25% = 75%

$6 ⇒ 75%

$A ⇒ 100%

A = $6* 100% / 75%

A = 8

Answer:

y = 120

Step-by-step explanation:

If x = y, they can be written as a fraction to show their proportionality as [tex]\frac{10}{80}[/tex]. This is equal to [tex]\frac{1}{8}[/tex], so when x = 1, y = 8. To find when y is equal to x when x = 15, just multiply y by 15. 15(8) = 120, so y = 120 when x = 15.

Answer:

120

Step-by-step explanation:

set up a proportion: 80/10=y/15

solve: 80*15=10y

1200=10y

y=120

Please remember to vote this answer as Brainliest if I earned it!

Answer:

31, 43, 57

Step-by-step explanation:

Work out the differences between the terms of the sequence:

[tex]1 \underset{+2}{\longrightarrow} 3 \underset{+4}{\longrightarrow} 7 \underset{+6}{\longrightarrow} 13 \underset{+8}{\longrightarrow} 21[/tex]

The differences between terms increase by 2 each time.

Therefore, from inspection of the pattern, the next three terms in the sequence are:

The correct answer is y = -2x.

Direct proportion can also be known as Direct variation. When the ratio of two quantities equals constant, we call it Direct Proportion. Direct Proportion is denoted by  [tex]\alpha[/tex] .  

Let us consider two quantities a and b, then the direct proportion between a and b can be expressed as,

                                          a  [tex]\alpha[/tex]  b

                                 =>    [tex]a/b = k[/tex] ( where k is constant)

                                 =>     [tex]a = kb[/tex] [tex]--- >[/tex] 1

Substitute a=x and b=y in 1, and then we get

                                          [tex]x = ky[/tex]

Therefore, the general form of an equation which satisfies direct proportion is x = ky.

[tex]y=1/2x-2, y=-2x+3,y=4/x[/tex]  are not in the form of [tex]x = ky[/tex].

So, The equation of direct proportion is y = -2x.

Answer:

Marc: 8 meters & 4 seconds

Prisha: 6 meters & 3 seconds

Step-by-step explanation:

Marc: If Marc travels 8 meters in 4 seconds it means that he has a speed of 2m/s

Prisha: If Prisha travels 6 meters in 3 seconds it means that she has a speed of 2m/s

To find speed we simply have to divide distance by time

The way that I figure out the answer was by trial and error. This is when we have to get random numbers and try them.

2 seemed a reasonable answer as it couldn't a number such as 5 as there is only 1 factor of 5 between 0 and 9. There are 4 factors of 2 between 0 and 9

Answer:

45 ∘,45 ∘ ,90 ∘

Step-by-step explanation:

Since, the angle is right angled isosceles triangle. One of the angles will be 90 ∘

. let the other two angles be x

Thus, sum of angles = 180

90+x+x=180

2x=90

x = 45 ∘

The measure of each angle is: 45 ∘ ,45 ∘ ,90 ∘
