1 mile is made up of 1760 yards.

If the library is 5 miles from the post office then the library is (5 x 1760) yards from the post office.  

5 x 1760 = 8800

So the library is 8800 yards from the post office.

If 5x - 3y = 1 and x = 2y - 4, then x • y = ?
Inessa05 [86]

Answer:

x = 2,  y = 3

Step-by-step explanation:

i) It is given that 5x - 3y =1

ii) It is also given that x = 2y - 4

iii) we can substitute the value of x from ii) in the equation in i) and we will get 5(2y - 4) - 3y = 1   ⇒ 10y - 20 -3y =  1   ⇒  7y = 21  ∴ y = 3

iv) substituting the value of y obtained in ii) we get x = (2 × 3) - 4 = 6 - 4 = 2.

v) Therefore x = 2.

I have a two digit number the sum of the digits is 12 the first digit is 4 Less Than 3 times the second what is my number​
nignag [31]

Answer:

84

Step-by-step explanation:

Let the first digit = x

Let the second digit =y

x + y = 12

x + 4 = 3*y

===========

From the second equation, we learn that x = 3y - 4

Put that into the first equation.

3y - 4 + y = 12          Combine the left side

4y - 4 = 12                Add 4 to both sides

4y = 16                     Divide by 4

4y/4 = 16/4        

y = 4  

=================

x + 4 = 12

x + 4 - 4 = 12-4

x = 8

So the number is 84

A cabinet shop wants to determine the effect of adhesive brands on the bonding of veneer to cabinets. The shop divides the cabin
vodomira [7]

Answer:

A. Randomized experiment.

Seee explanation below.

Step-by-step explanation:

Previous concepts

In a Randomized experiment the results can be use to establish causal inferences about means of control. and present two important characteristics:

a) "the independent or explanatory variable is controlled by direct manipulation.

b) "All other sources of variability are controlled by chance".

An observational study is an empirical but is nonexperimental investigation in order to see the effects caused by an specific treatment.

Solution to the problem

For this case we want to determine the effect of adhesive brands on the bonding of veneer to cabinets.

The experiment is conducted with 6 different groups defined with different adhesive and all the groups are the same except by the type of brand for the adhesive used.

So on this case we see that the variable of interest is controlled with direct manipulation with the creation of the 6 groups. And we have that all the the others sources of variability are controlled by chance since all the groups are identical except by the brand type.

So for this case the correct answer would be:

A. Randomized experiment.
