Answer:
Greenland offers the lowest unit rate, dollars per pound
Step-by-step explanation:
For McCoy, $4.5 = 5 pounds
Therefore $1 = 5pounds/4.5= 1.11 pounds
1 pound= 1/1.11= $0.9009
For Eat smart
$3=2 pounds
Therefore $1=2pounds/3 = 0.667 pounds
1 pound = 1/0.667= $1.499
For Greenland
$1/5= 1/4 pounds
$0.2=0.25 pounds
$1= 1.25 pounds
Therefore 1 pound= 1/1.25= $0.8
For Mother Nature
$0.95= 1 pound
Therefore Greenland offers the lowest unit rate at $0.8 per pound
The value of x where the expression –4x – 8 will be equivalent to –9x –1 will be 7/13.
<h3>How to calculate the value?</h3>
It should be noted that we are simply to find the value of x where the expression –4x – 8 will be equivalent to –9x –1.
This will be:
= +4x - 8 = -9x - 1.
4x + 9x = -1 + 8
13x = 7
Divide
x = 7/13
The value is 7/13.
