Answer is the ratio 42:63:15:20

=======================================================

Explanation:

The weight of A is 2/3 that of B. This flips to saying "the weight of B is 3/2 that of A". Because 3/2 = 1.5, we can then have this equation

B = 1.5A

The statement "C is 75% the weight of D" leads to the equation

C = 0.75D

----------------------------

The sum of A and B is triple that of the sum of C and D, giving us this equation:

A+B = 3(C+D)

Plug in the previous two equations we found in the previous section. Afterward, solve for the variable "A".

A+B = 3(C+D)

A+1.5A = 3(0.75D+D)

2.5A = 3(1.75D)

A = 3(1.75D)/2.5

A = 2.1D

----------------------------

Let's revisit the first equation we set up, and then apply substitution like so:

B = 1.5A

B = 1.5*2.1D

B = 3.15D

----------------------------

There's a lot of equations to keep track of. The key equations are these:

A = 2.1D

B = 3.15D

C = 0.75D

The one common factor of all these equations is the variable "D". This will be useful when setting up the ratio A:B:C:D

We'll go from the ratio

A:B:C:D

to

2.1D:3.15D:0.75D:1D

afterward we can divide all four parts by the GCF variable D, to arrive at

2.1:3.15:0.75:1

----------------------------

This last section will focus on converting each part of that ratio into integers. This is done by multiplying all four parts by 100 (as shown in the 2nd step).

Then we divide all parts by the GCF 5 to get the final reduced ratio.

2.1:3.15:0.75:1

100*2.1:100*3.15:100*0.75:100*1

210:315:75:100

5*42:5*63:5*15:5*20

42:63:15:20

Solve for x:

Answers

Answer:

X = 2

Step-by-step explanation:

First we'll need to simplify this equation:

Add 9x on both sides:

13x - 21 = 5

Add 21 on both sides:

13x = 26

Divide 26/13

26/13 = 2

X=2

(You can check this yourself by plugging x into the equation)

Priya is making burgers for a party. She has 5 pounds of meat and uses 1/3 of a pound for one burger. How many burgers can priya make?

Answers

Answer: Priya can make 15 burgers with 5 pounds of meat

Step-by-step explanation:

Step 1

From Priya's receipe,

1 burger can be made from  1/3 of a pound of meat  

  How many burgers can be made from 5 pound of meat

Step 2 Using the equation below, that

1 burger = 1/3 pound of meat

Therefore 5 pounds of meat

5 x 1 / 1/3 = 5/(1/3)

= 5 x3 = 15 Burgers.


For the inverse variation equation p=8/v what is the value of V when p = 4?
O 1/8
o 1/2
O 2
O 32

Answers

Answer:

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form

y*x=k or y= k/x

in this problem we have that

the value of the constant K is equal to 8

so

pv=8

Solve for V

v=8/p

Find the value of V for p=4

substitute the value of P in the formula

v=8/4=2

therefore

the answer is

the value of V is equal to 2

We'll need 2 points so we'll choose (-6, 0) and (0, -3).  

Let's calculate the slope (or 'm') using

Slope or m = (Y2 -Y1) ÷ (X2 -X1)

Slope ('m') = (-3 -0) / (0, - -6) = -3 / 6 = -1/2

Then we calculate the equation using:

(y - y1) = m • (x -x1)

(y - 0) = -1/2 * (x - -6)

y = -1/2 x -3

Source: http://www.1728.org/distance.htm

Step-by-step explanation:

Answer:

         x + 2y = - 6

Step-by-step explanation:

X-intercept:  (-6, 0)

Y-intercept:  (0, -3)    ⇒   b = -3

Slope:   [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{0+3}{-6+0}=-\dfrac12[/tex]

Slope-intercept form  y = mx + b

[tex]y=-\frac12x-3[/tex]        {multiply both sides by 2}

2y = - x - 6          {add x to both sides}

x + 2y = - 6

[tex]x = 8[/tex]

Step-by-step explanation:

1) Subtract 6 from both sides.

[tex]3(x + 1) = 33 - 6[/tex]

2) Simplify 33 - 6 to 27.

[tex]3(x + 1) = 27[/tex]

3) Divide both sides by 3.

[tex]x + 1 = \frac{27}{3} [/tex]

4) Simplify 27/3 to 9.

[tex]x + 1 = 9[/tex]

5) Subtract 1 from both sides.

[tex]x = 9 - 1[/tex]

6) Simplify 9 - 1 to 8.

[tex]x = 8[/tex]

Therefor the answer is, x = 8.
