Answer:
$17.15
Step-by-step explanation:
15% reduction means 100-15 = 85% of the previous
85/100 × 2200
1870 kWh
he saves:
0.055(2000 - 1870) + 0.05(2200 - 2000)
7.15 + 10
$17.15
12x+15y=34
2(-6X+5Y)=3
12x+15y=34
-12x+10y=6 = 25y=40 25/40 =0.25 then you plug that back into any original equation and you get the x
Step 1
Boiling point of mercury = 357℃
Let the boiling point of the lead be x
41/200 x=357
Step 2
41/200 x=357
41/200 x times 200/41 =357 times 200/41
x=1741.46
Step 3
The boiling point of lead is 1741.46
Result
41/200x=357
The boiling point of lead is 1741.46
Hope this helped
Answer:
Segment AB is corresponding to segment EF, and segment BC is corresponding to segment FG.Angle ABC is corresponding to angle EFG, and BCD is corresponding to angle HGF. If polygon EFGH is a dilation of polygon ABCD, then the scale factor is EFGH.
