Answer:

54/120

Step-by-step explanation:

Ratio to 54 seconds to 2 minutes is 9 : 20

Find:

Ratio to 54 seconds to 2 minutes

Computation:

We know that,

1 minutes = 60 second

So,

2 minutes = 120 second

Ratio to 54 seconds to 2 minutes = 54 / 120

Ratio to 54 seconds to 2 minutes = 27 / 60

Ratio to 54 seconds to 2 minutes = 9 : 20

Answer:

y is already isolated in the top equation

x = 4

y = 12

(4,12)

Step-by-step explanation:

y is already isolated in the top equation

plug y = 3x into bottom equation

5x + 2y = 44

5x +2(3x) = 44

5x + 6x = 44

11x = 44

x = 4

plug x = 4 into y = 3x

y = 3(4)

y = 12

I got you bro!

Answer:

{x,y} = {4-1}

You might be wondering how I got this, well here are the steps:

System of Linear Equations entered :

  [1]    2x + y = 7

  [2]    x - 2y = 6

Graphic Representation of the Equations :

   y + 2x = 7        -2y + x = 6  

Solve by Substitution :

// Solve equation [2] for the variable  x  

 [2]    x = 2y + 6

// Plug this in for variable  x  in equation [1]

  [1]    2•(2y+6) + y = 7

  [1]    5y = -5

// Solve equation [1] for the variable  y  

  [1]    5y = - 5

  [1]    y = - 1

// By now we know this much :

   x = 2y+6

   y = -1

// Use the  y  value to solve for  x  

   x = 2(-1)+6 = 4

Solution :

{x,y} = {4,-1}

I hope this has helped you and have a wonderful day!

4y^{2}+3y  

Step-by-step explanation:

First you need to distribute the values.  

(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials  

You Should get  

8y^{2}+6y  

Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.  

8y^{2}+6y/2  

Doing this you will get  

4y^{2}+3y

Answer:

These are confusing Beth , b/c you have to remember that they will add to 100%

Step-by-step explanation:

so

green = 3*  yellow

100% = green + yellow + 35% + 25%

100% = 3* yellow + yellow +60%

40% = 4* yellow

10% = yellow

30% = green

there are 14 purples in the bag , which is 35% of total

14/.35 = 40

there are a total of 40 pins

so

4    are yellow  (10% of 40  or 40* 0.1)

12 are green    (30% of 40  or 40*0.3)

14  are purple  (35% of 40 or 40*0.35)

10  are grey  (25% of 40  or 40*0.25 )

Answer:

It is better to buy 20 g of flour 3 for 3.50

Step-by-step explanation:

It is given that 20g of 3 for 3.50

It means 3 packets of 20 g is 3*20 =60

So, 60g  is for 3.50

So, 1 g =[tex]\frac{3.5}{60}[/tex]=0.05833 per gram.

Now, let's find unit rate for 40 g of 2 for 9.

2 packets of 40 gram = 2* 40 =80 grams

So, 80 grams costs 9

So, 1 gram =[tex]\frac{9}{80}[/tex] =0.1125

So, it is better to buy 20 g of flour 3 for 3.50
