Answer:
A=1/2 or A=0.5,A=2 negative 1 on top of two.
Step-by-step explanation:
3+0.5(4a+8)=9-2a
parentheses first
3+2a+4=9-2a
add the numbers
7+2a=<em>9</em><em>-</em><em>2</em><em>a</em>
<em>move</em><em> </em><em>terms</em>
<em>2</em><em>a</em><em>+</em><em>2</em><em>a</em><em>=</em><em>9</em><em>-</em><em>7</em>
<em>colle</em><em>ct</em><em> </em><em>the</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em><em>and</em><em> </em><em>subt</em><em>ract</em>
<em>4</em><em>a</em><em>=</em><em>2</em>
Answer:
C. (0, 7)
Step-by-step explanation:
Just use a graphing calculator.
A typical shower drain can remove 480 gallons of water in 3 hours.
For the first-rate;
1,440 gallons in 3 hours
We calculate the unit rate.
By Dividing the total volume by the total time,
1440 / 3 = 480 gallons/ hours
For the second rate:
960 gallons in 120 minutes
Converting minutes to hours:
120 minutes = 2 hours
We calculate the unit rate.
By dividing the total volume by the total time,
960 / 2 = 480 gallons / hour
For the third rate:
720 gallons in 1.5 hours
We calculate the unit rate.
By dividing the total volume by the total time,
720 / 1.5 = 480 gallons / hour
Now,
480 gallons/ hour = 480 / 60 gallons/ minute = 80 gallons per minute
