Solve for y: -3y=2x-p;x=-3,0,1

1 answer:

6 0

-3y = 2x - p |divide both sides by (-3)

y = -3/2x + p/3

x = -3 then y = -3/2 · (-3) + p/3 = 4.5 + p/3

x = 0 then y = -3/2 · 0 + p/3 = p/3

x = 1 then y = -3/2 · 1 + p/3 = -3/2 + p/3

Hence, the required inequality is x+y≤4, 7x+4y≤1150

<h2>What is inequality?</h2>

inequality, In mathematics, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

<h3>How to solve?</h3>

Let x be the number of adults and y be the number of campers.

There are rooms for 450 people, so

x+y≤450.

Each adult costs $7, then x adults cost $7x.

Each camper costs $4, then y campers cost $4y.

There is a maximum budget of $1,150, so

7x+4y≤1,150

Hence, you get the system of two inequalities:

x+y≤4

7x+4y≤1150

Daniele has 33 quarters and dimes in her piggy bank. The piggy bank contains a total of $4.95. Write and solve a system of equat

3241004551 [841]

Answer:the number of dimes is 22

the number of quarters is 11

Step-by-step explanation:

A dime is worth 10 cents. Converting to dollars, it becomes 10/100 = $0.1

A quarter is worth 25 cents. Converting to dollars, it becomes 25/100 = $0.25

Let x represent the number of dimes.

Let y represent the number of quarters.

Daniele has 33 quarters and dimes in her piggy bank. This means that

x + y = 33

The piggy bank contains a total of $4.95. This means that

0.1x + 0.25y = 4.95 - - - - - - - - -1

Substituting x = 33 - y into equation 1, it becomes

0.1(33 - y) + 0.25y = 4.95

3.3 - 0.1y + 0.25y = 4.95

- 0.1y + 0.25y = 4.95 - 3.3

0.15y = 1.65

y = 1.65/0.15 = 11

Substituting y = 11 into x = 33 - y, it becomes

x= 33 - 11 = 22
