Answer:
Step-by-step explanation:
A) 4x + 6 = 2x - 12
Subtract 6 from both sides
4x + 6 - 6 = 2x - 12 -6
4x = 2x - 18
Subtract 2x form both sides
4x - 2x = 2x - 18 - 2x
2x = -18
B) 24 = 6x - 18
6x - 18 = 24
6x - 6*3 = 24
6(x - 3) = 24
Divide both sides by 6
x - 3 = 4

Answer:
$8 /yd
Step-by-step explanation:
You probably want dollars per yard. To get that, divide dollars by yards:
$22/(2.75 yd) = $8 /yd
X equals 3 and y equals two
Answer:
A(t) = 1.032^t
Ring rate grows faster
Annual rate of ring: 4.03%
Step-by-step explanation:
A(t) = (1 + 3.2%)^t
A(t) = (1.032)^t
Ring:
(1 + 0.33%)^(12t)
(1 + 0.0033)^(12t)
(1.0033¹²)^t
1.040326705^t
Increase of (1.040326705 - 1) × 100
= 4.0326705%
Faster rate: ring
Answer:
20
Step-by-step explanation:
Knowing that it is a 30-gallon bathtub.
And it fills at a rate of 3 gallons per minute.
But also drains 1.5 gallons per minute.
So this is for the first minute.
3 - 1.5 = 1.5
So there will be 1.5 gallons of water in the tub after the first minute.
Now do,
30 ÷ 1.5 = 20
It will take 20 full minutes for the bathtub to fill up.
