Answer:

Length = 11 1/3 ft; Width = 4 2/3 ft

Step-by-step explanation:

First question:

The length is 2 more than twice the width, so

L = 2W + 2

Second question:

2L + 2W = 32

L = 2W + 2

Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.

2L + 2W = 32

2(2W + 2) + 2W = 32

4W + 4 + 2W = 32

6W = 28

W = 28/6 = 14/3 = 4 2/3

L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3

L = 11 1/3

W = 4 2/3

Answer: Length = 11 1/3 ft; Width = 4 2/3 ft

At Breakfast Break, 2 eggs and 1 sausage patty cost $2.23 and 3 eggs with 2 sausage patties cost $3.76. Assuming that these amounts only pay for the eggs and sausage, how much does one sausage patty cost?

Answers

I am thinking one sausage patty cost $4.25

Cost of one sausage patty is $0.83.

What is an equation?

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Given that,

Cost of 2 eggs and 1 sausage patty = $2.23,

Cost of 3 eggs and 2 sausage patties = $3.76.

Write above expression in equation form,

2 eggs + 1 patty = 2.23 (1)

3 eggs + 2 patties = 3.76 (2)

To find the cost of patty, multiply equation (1) with 3 and equation (2) with 2,

6 eggs + 3 patties = 6.69 (3)

6 eggs + 4 patties = 7.52 (4)

By solving equation (3) and (4)

1 patty = 0.83

The cost of 1 sausage patty is $0.83.

The ratio of cats to dogs is 8/6, which can be simplified to 4/3. The ratio of fish to birds is 20/2. Can it be simplified to 10? Why or why not? Answer in complete sentences.

Answers

Answer:

Not exactly. It can't be simplified as "10" but can be simplified as 10:1 or 10/1. (At least I'm pretty sure).

Step-by-step explanation:

Sorry if it didn't helped D:

If it did help, then thanks! :D

Ratios can only be written as 10:1. So the answer is no because you can’t write a ratio by just saying “10” you must write 10:1 or 10/1

Solve the equations:
1. 9x - 5 = 5x + 7
2. 8x - 2 = x - 16
3. 8x + 5 = 2x + 23
4. 2x + 8 = 5x + 20
5. 5(2x + 6) = 3x - 5

Answers

Answer:

5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x

step1:- 5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

step2:- 5x + 3x - 9x - 20 = 8x - 2x + 6 - 5

-x - 20 = 6x + 1

stp 3

-20 = 7x + 1

step 4

-21 = 7x

divide both sides by 7:-

thats the solution x = -3
