A quart is a 1/2 of a half dollar because half a dollor is 50 and a quart is 25 so thats half <span />
Answer:
2774
Step-by-step explanation:
start by multiplying 2 by 7, the answer is 14 put the 1 above the 8 in 1387 then put the 4 under the equation, similar to addition. repeat but next time when you multiply 2 by 8 add the 1 (from the previous multiplication) to the answer under and put the 1 from 17 on top of the 3. you get it?
<span><span>4a+6b=10
4a=10-6b
a=(10-6b)/4
a=(5-3b)/2
</span>
<span>2a-4b=12
2((5-3b)/2)-4b=12
(5-3b)-4b=12
5-7b=12
-7b=7
b=-1
</span>
<span>2a-4b=12
2a-4(-1)=12
2a+4=12
2a=8
a=4
a=4, b=-1 </span>
12a=48</span>
Answer:
see the explanation
Step-by-step explanation:
The given rate is
Create three different rates, that are all equivalent to this rate
<u>First rate </u>
1,440 gallons in 3 hours
Find the units rate
Divide the total volume by the total time
<u>Second rate </u>
960 gallons in 120 minutes
Find the units rate
Divide the total volume by the total time
Convert minutes to hours
<u>Third rate </u>
720 gallons in 1.5 hours
Find the units rate
Divide the total volume by the total time
<em>Convert gal/h to gal/min</em>
Remember that
Answer:
x<9
Step-by-step explanation:
-5(x-1) > -40 ---> divide each side by -5(you flip the inequality because of dividing by negative)
(x-1)<8 ---> add 1 to each side
x<9
