Taking into account the definition of a system of linear equations, the weigh of Flemish giant rabbit is 13.75 pounds.

A system of linear equations is a set of two or more first degree equations, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, a solution to a system of two or more linear equations is a solution that simultaneously satisfies all the equations in the system

In this case, a system of linear equations must be proposed taking into account that:

You know:

The system of equations to be solved is

f= 5×h

f= h +11

There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, substituting the first equation in the second you get:

5×h= h + 11

Solving:

5×h- h= 11

4×h= 11

h= 11÷ 4

h= 2.75

Substituting this value in the first equation of the system of equations:

f= 5×2.75

f= 13.75

Finally, Flemish giant rabbit weighs 13.75 pounds.

Considering the situation given, it is found that:

At the null hypothesis, we test if they average the same amount of trouble hours as last year, that is, of 2000 trouble hours, thus:

[tex]H_0: \mu = 2000[/tex]

At the alternative hypothesis, we test if this amount has increased, that is:

Answer:

52 ft.

Step-by-step explanation:

In this case, we need to calculate a perimeter, which is the sum of all sides of the rectangle.

So, rectangles has opposite sides equal, therefore, the perimeter should be:

; having L as the larger side.

Hence, the strip of wallpaper needs to be as least 52 ft.

Answer: 210 grams

Step-by-step explanation:

Given,

One cube= 5 grams of paint

According to question,

There are= (9*2)+(6*4) cubes

               = 18+24 cubes

                =42 cubes

Total paint needed= 5*42 grams

                               =210 grams(answer)

Answer:

x=36

Step-by-step explanation:

first take six away from both sides to get 3/4x=27

then divide 27 by the numerator 3 to get 9. Then multiply 9 by the denominator 4 to get 36. So 3/4 of 36=27+6=33

3/4x+6=33

We move all terms to the left:

3/4x+6-(33)=0

Domain of the equation: 4x!=0

x!=0/4

x!=0

x∈R

We add all the numbers together, and all the variables

3/4x-27=0

We multiply all the terms by the denominator

-27*4x+3=0

We multiply elements

-108x+3=0

We move all terms containing x to the left, all other terms to the right

-108x=-3

x=-3/-108  

x=1/36

Answer:

the amount of interest is $100.80

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6.3%/100 = 0.063 per year,

then, solving our equation

I = 400 × 0.063 × 4 = 100.8

I = $ 100.80

The simple interest accumulated

on a principal of $ 400.00

at a rate of 6.3% per year

for 4 years is $ 100.80.

Answer:

3

Step-by-step explanation:

There are 3 because only numbers with values higher than 0 are counted, unless there is a decimal.

Becuase there is no decimal at the end of this number, there are only 3 counted. Those counted are 1 2 and 9, and all of the 0s dont count.

If there was a decimal at the end this number, it would have been 12

f= −x+3

     7x

Step-by-step explanation:

fx       =  −1          3

x        7     x+  7

-------------------------

x                 x

f= -x+3

       7x

f= -x+3

       7x

Answer:

A.

Step-by-step explanation:

f(x) = (3-x)/7

First we find x in terms of f(x:-.

7f(x) = 3 - x

x + 7f(x) = 3

x =  3 - 7f(x)

Now we replace x by f-1(x) and f(x) by x:

f-1(x) = 3 - 7x.

Step-by-step explanation:

Basically, let's represent the amount of money earned in

July with x

and

August with x+90

x+(x+90)=350

2x+90=350

2x=350-90

2x=260

x=260÷2

x=130

So, Wanda earned $130 babysitting in July and in July, 130+90=$220.

Answer:

1/3 = 2 2/3 eighths.

Step-by-step explanation:

There are 2(2/3) eights in 1/3.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Eighths = 1/8

Now,

(1/8)x = 1/3

Solve for x.

x = 1/3 x 8/1

x = 8/3

x = 2(2/3)

Thus,

There are 2(2/3) eights in 1/3.
