<u>Answer</u>:
x = 20
<u>Explanation</u>:
all the interior angles in the triangle is 180°
<u>therefore</u>:
4x - 17° + 71° + 46° = 180°
4x + 100° = 180°
4x = 180° - 100°
4x = 80°
x = 20°

Step-by-step explanation:
Step one:
given
current (older) fridge
electricity charges= $17 monthly
maintenance costs= $220
let the number of months be x
and the total cost be yo
the expression for the cost for the old fridge is
yo=220+17x---------1
New fridge
electricity charges= $6 monthly
costs= $1,050
let the number of months be x
and the total cost be yn
the expression for the cost for the old fridge is
yn= 1050+6x---------2
Hence the system of equation for the situation is
yo=220+17x---------1
yn= 1050+6x---------2
Step two
for 10 years there are 12*10= 120 months
put x= 120 in both expressions and compare the total
yo=220+17(120)---------1
yo=220+2040
yo=$2,260
yn= 1050+6(120)---------2
yn=1050+720
yn=$1770
<u><em>Based on the analysis it will be less expensive to get the new fridge, hence buying the new fridge is worth it.</em></u>
Answer:
16
Step-by-step explanation:
$4.35 x 15 hr = $65.25
$100 - $ 65.25 = $34.75
$34.75 / $2.2 = 15.79 bushels
round up to 16
16 x 2.20 = $35.20
