Answer:
1210 acres
Step-by-step explanation:
Given data
let the old farmland be x acres
new farmland = 968 acres
therefore
let us find 20% of the old farmland
=20/100x
=0.2x
Hence
968+0.2x=x
collect like terms
968=x-0.2x
968=0.8x
x= 968/0.8
x=1210 acres
This is true.
These are perfect squares: 4, 9, 25. These are not: 7, 8, 11
Answer:
x^2-4/7x-12/49=0
x= 6/7 and -2/7
Step-by-step explanation:
The unit rate of the proportional relationship y = 3x is 3
<h3>How to determine the unit rate?</h3>
The proportional relationship is given as:
y = 3x
Divide both sides by x
y/x = 3
For a proportional relationship y/x = k;
The unit rate is 3
This means that the unit rate of the proportional relationship y = 3x is 3
