Answer:

Mike had 14 slice of bread in his loaf while

Joey had 8 slice of bread in his loaf.

Step-by-step explanation:

We should note that a sandwich is made up of two slice of bread.

that is :

A Sandwich = 2 Slice of bread

and for bologna to be in a sandwich, you will have 2 slice of bread together.

So, For Mike,

2 slice of bread × 5 Sandwich = 10 Slice of bread

Remaining Slice of bread = 4 Slice

Total Slice of bread in Mike loaf = 10 + 4

= 14 slice of bread was in Mike loaf of bread.

For Joey

A sandwich = 2 Slice of bread

2 slice of bread × 4 Sandwich = 8 Slice of bread

Remaining slice of bread = 0

Total slice of bread in joey loaf = 8 slice of bread.

Answer:

The correct answer is 28 slices of bread

Step-by-step explanation:

Let there be BO slices of bologna and BR slices of bread in a package.

Mike use  BO/5  ( 5 slides per sandwich) and he use bread, BR- 4= BO/5 x2  

Joey use (BO-4)/4 and BR=(BO-4)/4 x2

We know BO and BR are the same for each one ,  so we can replace BR in one equation and Isolate BO

((BO-4)/4 x2)- 4= BO/5 x2  

We divide each term by 2  

((BO-4)/4 )- 2= BO/5

BO/4-1 -2=BO/5

BO/4-3=BO/5

BO/4- BO/5=3

5BO-4BO/20=3

1BO/20=3

BO= 3x 20

BO=60

 

and BR=(BO-4)/4 x2

BR=(60-4)/4 x2

BR=(56)/4 x2

BR=14 x 2= 28

A=75(125+81/2) how do you this equation? pls Help!!!
Maru [420]
Closing parenthesis is misplaced. Should be: 
<span>A = h(b₁ + b₂)/2 </span>

<span>h = 75 ft </span>
<span>b₁ = 125 ft </span>
<span>b₂ = 81 ft </span>

<span>Then it's just plug & grind: </span>

<span>A = 75(125 + 81)/2 ft² = 75·206/2 ft² = 75·103 ft² = (7500 + 225) ft² = 7725 ft² </span>

<span>If you follow that, it will guide you through any other, similar p</span>

The perimeter of a rectangular field is 84 yards. The ratio of the length to the width is 2:1. What are the length, width and ar
Ivenika [448]

Given:

  • the perimeter of a rectangular field is 84 yards
  • the ratio of the length to the width is 2:1

To find:

  • the length
  • the width
  • the area

Answer:

Let's assume that the length is 2x and the width is 1x.

We know that the formula to find the perimeter of a rectangle is as follows:

Perimeter = 2 × (Length + Width)

Substituting the values that we have, into the formula above,

84 = 2 × (2x + 1x)

84 = 2 × 3x

84/2 = 3x

42 = 3x

x = 42/3

x = 14

Since we know the value of 'x', let's use it to find the length and the width.

Length = 2x = 2 × 14 = 28

Width = 1x = 1 × 14 = 14

Since we now know the length and the width, let's find the area of the rectangle.

The formula to find the area of a rectangle:

Area = Length × Width

Substituting the values we have into the formula,

Area = 28 × 14

Area = 392

Therefore, the area of the rectangle is 392 square yards.

Hope it helps. :)

In a jar of coins, the ratio of nickels to dimes is 2:7. If the jar contains 350 nickels, how many dimes are there? A) 175 B) 35
Dvinal [7]
No nickles = 2x and that of dimes = 7x so 2x = 350 get x and the no of dimes
so like 2x = 350 divide by 2 on both sides so x = 175 ... and no of dimes = 7*x = 7*175 = 1225
Hope it helps :)
