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
If u tell me the solution's like are u evaluating or what, which method is it i can tell u the answer <span />
36 3/4 = 36.75
36 3/8 = 36.375
37 1/2 = 37.5
36 5/8 = 36.625
(36.75 + 36.375 + 37.5 + z) / 4 = 36.625
(110.625 + z) / 4 = 36.625
110.625 + z = 36.625 * 4
110.625 + z = 146.5
z = 146.5 - 110.625
z = 35.875 or 35 7/8 <===
First calculate that numeric value. It cannot be done immediately without calculations.
if 85% of studends liked mystery that means that 100% - 85% = 15% didnt like.
Those 15% are 30 that were given in text. Now we can calculate this using proportion:
15% 30 students
85% x students
we use cross multiplication:
15*x = 30*85
x = 30*85/15
x = 170
Answer is 170
