Step-by-step explanation:
the side with the biggest angel across form it has the longest side
the unknown angle would be 180-50-20=110
so it would go 20,50,110
The number of decorative pillows did the realtor arrange on each twin bed and queen bed is 6 and 9 respectively.
<h3>Simultaneous equation</h3>
let
- Number of decorative pillows for twin bed = x
- Number of decorative pillows for queen bed = y
x + y = 15
2x + y = 21
From equation (1)
x = 15 - y
- Substitute x = 15 - y into (2)
2x + y = 21
2(15 - y) + y = 21
30 - 2y + y = 21
- 2y + y = 21 - 30
-y = -9
y = 9
Substitute y = 9 into
x + y = 15
x + 9 = 15
x = 15 - 9
x = 6

Answer
Find out the how much fertilizer will Timothy need for two fields, one that is 22.5 acres and one that is 38.25 acres .
To proof
As given
Timothy is putting fertilizer on a field after planting some crops
The directions on the barrel state to use 0.75 quarts for each acre of land.
fertilizer will Timothy need for 22.5 acres = 22.5 × 0.75
= 16.875 quarts
fertilizer will Timothy need for 38.25 acres = 38.25×0.75
= 28.6875 quarts
total fetilizer Timothy need for two fields = 16.875 + 28.6875
= 45.5625
= 45.6 ( approx )quarts
Therefore the total fertilizer will Timothy need for two fields be 45.6 ( approx )quarts .
Hence proved
