Answer:
x=8a
Step-by-step explanation:
(3/a) x - 4 = 20
add 4 to both sides
(3/a) x = 24
Divide by 3/a
x = 24 / (3/a)
Use KCF (keep change flip)
x = (24/1) x (a/3)
x = 24a / 3
simplify
x = 8a
A negative average rate of change means that as x increases, y decreases. That means that the graph goes down to the right.
The chart showing the quantities and prices is;
Best Deal 1
Quantity of Flour Price
3 pounds $5.25
5 pounds $9.75
7 pounds $12.60
10 pounds $14.20
12 pounds $18.24
Answer:
difference between last weeks best deal = $0.3
Step-by-step explanation:
Let's calculate the unit price for each of the quantities in the chart.
For quantity of 3 pounds;
We have; unit price = 5.25/3 = $1.75
For 5 pounds;. Unit price = 9.75/5 = $1.95
For 7 pounds; unit price = 12.6/7 = $1.8
For 10 pounds; unit price = 14.2/10 = $1.42
For 12 pounds; unit price = 18.24/14 = $1.3
Thus, last weeks best deal is the lowest = $1.3
Thus; difference between last weeks best deal is given as;
= this weeks best deal - last weeks best deal
This gives;
$1.6 - $1.3 = $0.3
Answer:
The difference between the two position = 20,028 feet
Step-by-step explanation:
North America highest peak distance above sea level = 20,310 feet
Death valley distance below the sea level = 282 feet
Let the sea level be = X
Highest peak point = Y
Death valley point = Z
So As per question
Distance from X to Y = 20,310 feet
Distance from X to Z = 282 feet
So, difference between two points = (X + Y ) - (X + Z ) = Y - Z
So , Y - Z = (20,310) - (282) = 20,028 feet
Hence the difference between the two position = 20,028 feet Answer
