Answer:
12a. 45+0.5x+2x+x = 150
12b. the three unknown sides are 30ft, 60ft, and 15ft.
Step-by-step explanation:
12a. the fence is 150ft. so
45+0.5x+2x+x = 150
12.b solve the equation from 12a.
45+0.5x+2x+x = 150
7x/2 = 105
7x = 210
x= 30
0.5(30) = 15ft
2(30)=30ft
x= 30ft
the three unknown sides are 30ft, 60ft, and 15ft.
Answer:
y=2, x=1
Step-by-step explanation:
3x-6y=12(x2)
5x-2y=10(x6)
Eliminate y
6x-12y=12
<u>3</u><u>0</u><u>x</u><u>-</u><u>1</u><u>2</u><u>y</u><u>=</u><u>6</u><u>0</u><u> </u>
-24x =-48
divide both sides by -24
-24x/-24=-48/-24
y=2
to get our x
3x-6(2)=12
3x-12=12
3x=12+12
3x=24(divide both sides by 3)
x=1
Answer:
Step-by-step explanation:
Charger per 60 sec. = $0.30
Total monthly bill(Sept.)
= $51
0.30 × 120 = 51-36
= 15 (Monthly base fee)
October bill = 165 × 0.30
= 49.5 - 15
October usage bill =$34.5
