Answer:

No

There are infinitely many solutions to the system.

{36x+21y=24312x+7y=81

Multiply the second equation by 3.

3(12x+7y36x+21y=81)=243

Subtract this new equation from the first equation.

36x+21y−(36x+21y0+0=243=243)=0 true

There are infinitely many values of x and y are possible.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

Two school groups go to a roller skating rink.

One group pays $243 for 36 admissions and 21 skate rentals.

The other group pays $81 for 12 admissions and 7 skate rentals.

Let x represent the cost of admission and let y represent the cost of a skate rental.

We have a system of equations,

36x + 21y = 243   {equation 1}

12x + 7y = 81        {equation 2}

Simplifying equation 1 we get,

36x + 21y = 243  

Divide by 3,

12x + 7y = 81      

That means, there are infinitely many solutions possible.

Therefore, there are infinitely many solutions possible.

Answer: Answer is -11.95

You can give the unknown value as x to make things easier

( x + 1.75 ) / 2 = -5.1

Find the value of x:

x + 1.75 = –5.1 x 2

x + 1.75 = -10.2

x = -10.2 – 1.75

x = -11.95

Explanation:

Answer:

1) Not Similar. 2/6 does not equal 6\12

2) Yes. 5/3 = 15/9

3)Yes. 10/30=8/24

4) Not Similar. 13/16 does not equal 16/21.

5) Not Similar. 28/48 and 42/36 do not reduce to the same value.

6)No. The angles are not the same.

Step-by-step explanation:

Ask yourself, is it proportional? Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

In other words, ifthe corresponding sides reduce down to the same value, they are similar.

Answer:

B C and D

Step-by-step explanation:

that your unit rate is gonna be 3 dollars for a pound because at one pound it is at 3 dollars.

when it hits 24 it is above the 8 in pounds so it will be 24 dollars for 8 ponds

it is non proportional relationship because the line does not cross back and touch the origin

Answer:

A is true. C is true. D is true

Step by-step explanation:

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

Step-by-step explanation:

What you are going to do is for each value of x (which is the value to the right on the table) you will find the Y value.

So for X = 0

y = 2(0)+5 = 5

x = 1

y = 2(1)+5 = 7

x = 3

y = 2(3)+5 = 11

x = 5

y = 2(5)+5 = 15

x = 10

y = 2(10)+5 = 25

Now for what you do is place the correspanding value into the graph.

(x,y) = (0,5), (1,7), (3,11),(5,15),(10,25)

Answer:

Option 4: 10d + 5

Step-by-step explanation:

Given the algebraic expression, 5(2d + 1), which represents the fines per day, d, for overdue books.

In order to determine the equivalent algebraic expression of 5(2d + 1), we must distribute 5 into the terms inside the parenthesis:

5(2d + 1)

= 5(2d) + 5(1)

[tex]\fbox{\textsf{= 10d + 5 }}[/tex]

Therefore, the equivalent expression is: 10d + 5.

Answer:

The answer i got is this -16 2/3, which i think is greater than -16

The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

A hole needs to arrive at no less than 72 feet subterranean level. This implies it should be multiple 1/2 times its ongoing profundity. This profundity is addressed by the imbalance 4 ¹/₂ d < - 72, where d is the ongoing profundity of the burrow.

4 ¹/₂ d < - 72

Simplify the inequality, then we have

4 ¹/₂ d < - 72

4.5d < - 72

d < - 72 / 4.5

d < - 16

The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.
