<u>Given:</u>

Turkey bought = 5 pound

Cost of 5 pound of turkey = 14.45

<u>To find:</u>

Cost of 7 pound of turkey

<u>Solution:</u>

Using unitary method, if the cost of 5 pound of turkey is 14.45 then the cost of one pound of turkey would be \frac{14.45}{5}=2.89

Therefore, the cost of one pound of turkey is 2.89.

So, cost of 7 pound of turkey = 2.89\times7=20.23

Thus, 7 pounds of turkey costs 20.23 units.

<u>Unitary method:</u>

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.

What is the slope of a line perpendicular to the line whose equation is 5x+6y=425x+6y=42. Fully reduce your answer.
Vlada [557]

Answer:  m= 1/420

Step-by-step explanation:

5x + 6y - 6y - 425x = 42

5x -425x = 42

0 = -420x - 42

m = -420

slope of a perpendicular line = 1/420

if that helps.

Which could be the first step in solving this system of equations by substitution?
Ainat [17]

Answer:

The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)

solve and get

(2.5,17.5)

or x= 2.5 y=17.5

Step-by-step explanation:

The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x

7x-x=15

6x=15

x=2.5

Then we can solve for y

y=7(2.5)

y=17.5
