Answer:

Step-by-step explanation:

Each of the quantities is described in terms of the number of Schnauzers, and that is the number we are asked for. It is convenient to write an equation for the number of Schnauzers. We choose to use s for the variable representing that number.

  s = # of Schnauzers

  s+3 = # of Scotties, 3 more than the number of Schnauzers

  2s-5 = # of Wire-haired Terriers, 5 less than twice the number of Schnauzers

The total number of dogs is then ...

  (s+3) +(s) +(2s-5) = 78

  4s -2 = 78 . . . . simplify

  4s = 80 . . . . . . add 2

  s = 20 . . . . . . . divide by 4

There were 20 Schnauzers at the dog show.

Answer: See explanation

Step-by-step explanation:

Let the number of hamburger he ate on Monday be represented by x.

Monday = x

Tuesday = 0

Wednesday = x + 4

Thursday = 0

Friday = 3(x + 4)

Total hamburgers ate = 26

To find the amount of hamburger ate each day we add the number of hamburger ate per day all together. This will be:

= x + 0 + x + 4 + 0 + 3(x+4) = 26

2x + 4 + 3x + 12 = 26

5x + 16 = 26

5x = 26 - 16

5x = 10

x = 10/5

x = 2

Monday = x = 2 hamburgers

Tuesday = 0

Wednesday = x + 4 = 2 + 4 = 6 hamburgers

Thursday = 0

Friday = 3(x + 4) = 3(2 + 4) = 18 hamburgers

Step-by-step explanation:

If the sum of 1 and 3 times a number is 22, then x=7 is the solution and graph that represents the number

Two or more expressions with an Equal sign is called as Equation.

Given,

The sum of 1 and 3 times a number is 22.

Let the unknown number be x

1+3x=22

Now subtract 1 from both the sides

1+3x-1=22-1

3x=21

Divide both sides by 3

x=7

So the solution of sentence sum of 1 and 3 times a number is 22 is 7.

x=7 is the equation of graph that represents the number

Hence x=7 is the equation of graph that represents the number

Complete question :

a researcher compared the Heights and shoe sizes for 50 men, selected at random. The equation shown describes a line of best fit for the data, where X is the shoe size and y is the height, in inches (y=1.6x + 58)

Based on the equation, what is the approximate shoe size for a man having a height of 60 inches

Answer:

1.25

Step-by-step explanation:

Given the regression equation :

y=1.6x + 58

X = shoe size ; y = height

Using the equation, the approximate shoe size of a man with a height of 60 will be ;

60 = 1.6x + 58

60 - 58 = 1.6x

2 = 1.6x

2/1.6 = 1.6x / 1.6

x = 2 / 1.6

x = 1.25

Hence, approximate shoe size of a man with a height of 60 will be 1.25

x+12=86

The equation that can be used to find x is x + 12 = 86

A linear equation is of the form:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the number of seashells in the collection before the 12 were added.  Hence to find x, we use the equation:

x + 12 = 86

Step-by-step explanation:

Sally visited 16 stores when shopping for 2 hours.

Since Sally could look in 6 stores in 45 minutes. Hence:

Time spent in each store = 45 minutes/6 stores = 7.5 minutes per store.

Given a time of 2 hours = 2 hours * 60 minutes per hour = 120 minutes

Number of stores visited in 2 hours = 120 minute / 7.5 minute per store = 16 stores

Therefore Sally visited 16 stores in 2 hours.

Answer:

There are [tex]2.6\times 10^{4}[/tex] spectators in the soccer stadium.

Step-by-step explanation:

From this statement, we can calculate the number of spectators in a soccer stadium by dividing the amount of bacteria among the spectators in a soccer stadium by the amount of bacteria in the human body. That is:

[tex]x = \frac{2.6\times 10^{18}\,bacteria}{1\times 10^{14}\,bacteria}[/tex]

[tex]x = \frac{2.6}{1}\times \frac{10^{18}}{10^{14}}[/tex]

[tex]x = 2.6\times 10^{18-14}[/tex]

[tex]x = 2.6\times 10^{4}[/tex]

There are [tex]2.6\times 10^{4}[/tex] spectators in the soccer stadium.

Answer:

[tex]log_3(\frac{7}{16}) =-0.753[/tex]

Step-by-step explanation:

Use the laws of log()

[tex]log_x(\frac{a}{b}) =log_x(a)-log_x(b)[/tex]

[tex]log_3(\frac{7}{16}) =log_3(7)-log_3(16)[/tex]

[tex]log_3(\frac{7}{16}) =log_3(7)-log_3(4^2)[/tex]  you can move exponent outside of log()

[tex]log_3(\frac{7}{16}) =log_3(7)-2log_3(4)[/tex]  

[tex]log_3(\frac{7}{16}) =(1.771)-2(1.262)[/tex]

[tex]log_3(\frac{7}{16}) =-0.753[/tex]

The required value of log₃ (7/16) is 0.753 which is determined by properties of logarithms.

There are four basic properties of logarithms:

logₐ(xy) = logₐx + logₐy.

logₐ(x/y) = logₐx - logₐy.

logₐ(xⁿ) = n logₐx.

logₐx = logₓa / logₓb.

The functions of logarithmic are given in the question

log₃ 4 = 1.262 and log₃ 7 = 1.771

We have to determine the value of log₃ (7/16)

⇒ log₃ (7/16) = log₃ 7 - log₃ 16

⇒ log₃ (7/16) = log₃ 7 - log₃ 4²

Using property of logarithm logₐ(xⁿ) = n logₐx.

⇒ log₃ (7/16) = log₃ 7 - 2 log₃ 4

Substitute the values of log₃ 4 = 1.262 and log₃ 7 = 1.771 in the above equation,

⇒ log₃ (7/16) = 1.771 - 2(1.262)

⇒ log₃ (7/16) = 1.771 - 2.524

⇒ log₃ (7/16) = 0.753

Therefore, the required value of log₃ (7/16) is 0.753.
