Answer:
5 pounds
Step-by-step explanation:
Given that:
Amount of gift card = $80
Cost of coffee per pound = $8.24
Amount left in the card = $38.80
To find:
Number of pounds of coffee bought = ?
Solution:
Let the number of pounds of the coffee bought =
pounds
Cost of 1 pound = $8.24
Cost of
pounds = $8.24 ![\times x](https://tex.z-dn.net/?f=%5Ctimes%20x)
Writing the equation as per question statement:
![80 - 8.24x = 38.80\\\Rightarrow 80 - 38.80 = 8.24x\\\Rightarrow 8.24x = 41.2\\\Rightarrow x = \dfrac{41.2}{8.24}\\\Rightarrow \bold{x = 5\ pounds}](https://tex.z-dn.net/?f=80%20-%208.24x%20%3D%2038.80%5C%5C%5CRightarrow%2080%20-%2038.80%20%3D%208.24x%5C%5C%5CRightarrow%20%208.24x%20%3D%2041.2%5C%5C%5CRightarrow%20x%20%3D%20%5Cdfrac%7B41.2%7D%7B8.24%7D%5C%5C%5CRightarrow%20%5Cbold%7Bx%20%3D%205%5C%20pounds%7D)
Therefore, 5 pounds of coffee was bought.
24 units by 15 units. Divide the original feet by 5 to get the units.
Answer:
z=-21
Step-by-step explanation: (9-3)/2=(6+z)/5
We move all terms to the left:
(9-3)/2-((6+z)/5)=0
We add all the numbers together, and all the variables
-((z+6)/5)+6/2=0
We add all the numbers together, and all the variables
-((z+6)/5)+3=0
We multiply all the terms by the denominator
-((z+6)+3*5)=0
We calculate terms in parentheses: -((z+6)+3*5), so:
(z+6)+3*5
We add all the numbers together, and all the variables
(z+6)+15
We get rid of parentheses
z+6+15
We add all the numbers together, and all the variables
z+21
Back to the equation:
-(z+21)
We get rid of parentheses
-z-21=0
We add all the numbers together, and all the variables
-1z-21=0
We move all terms containing z to the left, all other terms to the right
-z=21
z=21/-1
z=-21
