Ravi Had 124 Dollars To Begin With. He Just Spent B Dollars. Using B , Write An Expression For The Number

Answers

Answer 1
We know that Ravi has 124$, but we don’t need how much he spent! So, for the money he’s spent we are using B to represent it. The way I see the expression is:

124 - B = T

B is how much money he spent.
T is his total after.

I hope this helped! Good luck :D
Answer 2

An expression for the number of dollars he has left is: 124 - B = T

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.

Answer:

length= 35 feet and width= 10 feet

Step-by-step explanation:

You are given the perimeter of the rectangular deck is

90 feet.

2 x length + 2 x width = 90 You are also given that the deck's length is 5 feet less than 4 times it's width. That is length = 4 x width - 5

Those two equations are your system of linear equations. The second equation can be plugged into the first equation. This gives us an equation entirely in terms of width.  

2x (4 x width - 5) + 2 x width =90

Distribute the 2 though

8 x width - 10 + 2 x width = 90

Combine like terms with width.

10 x width - 10 = 90

Add 10 to both sides.

10 x width = 100

Divide both sides by 10 width = 100

Now you can plug width into your original equation for length above. Recall: length = 4 x width - 5

Length = 4 x 10 - 5

Length = 40 - 5

Length = 35

length is 35 feet and width is 10 feet

Please give me explanations too.

No Solution

Step-by-step explanation:

If we solve for the equation, we get a statement that isn't true.

9x + 7 = 9x - 4

-9x        -9x

7 = - 4

*subtract 9x from both sides*  

We know that 7 ≠ -4, so there aren't any solutions to this problem.

Answers

Answer:

12 shirts

Step-by-step explanation:

First, let x = # of shirts and y = total cost in $. Then create an equation with x and y representing each company. The first company is y = 9.65x + 43 and the second company is y = 8.40x + 58. Since we need to find the # of shirts that would result in the equal total cost, we need to find x when y is equal to the other. Thus here is the setup: 9.65x + 43 = 8.40x + 58, and we would get 1.25x = 15, so x = 12.

First you set up your equations
Company 1–> 9.65x+43
Company 2–> 8.40x+58

Next you set them equal to each other
9.65x+43=8.40x+58
9.65x-8.40x=58-43
1.25x=15/1.25
x=12
When you plug 12 into both equations you’ll get that they both equal 158.8

The owner of a lemonade stand mixes juice that costs 2 dollars per gallon with juice that costs 7 dollars per gallon. She gets 20 gallons of punch that costs 4 dollars per gallon. How much of each juice does she use?

Answers

Answer:

8 gallons at $7

12 gallons at $2

Step-by-step explanation:

x gallons at $7 with the remaining (20 - x) gallons at $2 to get 20 gallons at $4

x(7) + (20 - x)(2) = 20(4)

Distribute

7x + 40 - 2x = 80

Combine like terms

5x + 40 = 80

Subtract 40 from both sides

5x = 40

Divide both sides by 5

x = 8 gallons at $7

20 - x = 12 gallons at $2

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ - 3.5 = - 4.6x - 5.1

Now,

Solve the expression as;

The expression is,

⇒ - 3.5 = - 4.6x - 5.1

Solve for x as;

⇒ - 3.5 + 5.1 = - 4.6x

⇒ 1.6 = - 4.6x

⇒ -4.6x = 1.6

⇒ x = 1.6 / - 4.6

⇒ x = - 16/46

⇒ x = - 8/23

Thus, The solution of the expression will be;

⇒ x = - 8/23
