jane loves animals. She has an equal number of beetles, birds and spiders as pets. Apart from human legs, there is a total of 27

kherson [118]

Answer:

16.875 spiders

Step-by-step explanation:

Given

Let

$B = Beetles$

$C = Birds$

$S = Spiders$

So, we have:

$B = C = S$ --- equal amounts

$6B + 2C + 8S = 270$ --- the legs

Required

The number of spider

Since she has an equal amount of B, C and S;

The expression can be written as:

$6B + 2C + 8S = 270$

$6S + 2S + 8S = 270$

$16S = 270$

Solve for S

$S = \frac{270}{16}$

$S = 16.875$

<em>The result of the solution does not represent real life situation because it it is not possible to have a fraction number of spider</em>

Consider the line 7x+9y=5

alisha [4.7K]

Answer:

The slope of a line parallel to this line will be: -7/9

The slope of the perpendicular line will be:

$\frac{-1}{\frac{-7}{9}}=\frac{9}{7}$

Step-by-step explanation:

We know the slope-intercept form

$y=mx+b$

Here,

m is the slope

b is the y-intercept

Given the equation

$7x+9y=5$

simplifying to write in the lope-intercept form

$y=-\frac{7}{9}x+\frac{5}{9}$

Thus, the slope of the line is: -7/9

The slope of a line parallel to the line:

We have already determined that the slope of the line is: -7/9

We know that the parallel lines have the same slope.

Thus, the slope of a line parallel to this line will be: -7/9

The slope of a line perpendicular to the line:

We have already determined that the slope of the line is: -7/9

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

Thus, the slope of the perpendicular line will be:

$\frac{-1}{\frac{-7}{9}}=\frac{9}{7}$

People travel by bus or by train from hiraddug station on tuesday 420 people travelled by bus from the station the ratio of the

goldenfox [79]

The number of people travelled by train from the station on tuesday is 357.

Let us assume the number of people who travelled by train from the station on tuesday be x. Using the concept of ratio and proportion to solve and calculate x.

Forming the ratio-

20 : 17 = 420 : x

Solving the ratio and proportion for the value of x

x = (420 × 17) ÷ 20

Performing multiplication in numerator

x = 7140 ÷ 20

Performing division on Right Hand Side of the equation

x = 357

Therefore, based on the information, 357 people used to travel.

1/3(x - 10) = - 4<br><br> x = ?

ki77a [65]

Answer:

x = -2

Step-by-step explanation:

1/3(x - 10) = - 4

1/3x - 10/3 = - 4

1/3x = -4 + 10/3

1/3x = -2/3

x = -2/3 · 3

x = -2
