Answer:
24
Step-by-step explanation:
Let t represent the volume of the tank in gallons. Then we have ...
(1/8)t + 15 = (3/4)t . . . . . . . . . . . adding 15 gallons fills the tank to 3/4
15 = (6/8 -1/8)t = (5/8)t . . . . . . . subtract 1/8t
15(8/5) = (8/5)(5/8)t . . . . . . . . . multiply by 8/5 (the inverse of 5/8)
24 = t
The tank holds 24 gallons.
Answer:
ans=10
Step-by-step explanation:
Answer:
3. 9x+5+x-7=25
4. 10x-2=25
5. 10x=27
Step-by-step explanation:
3. 9x+5+x-7=25
4. 10x-2=25
10x=25+2
5. 10x=27
x=27÷10
x=2.7
|x – 55| = 4.2
where x is the speed.
-4.2 < x - 55 < 4.2
-4.5 + 55 < x < 55 -4.2
50.8 < x < 59.2
The upper boundary for x is 59.2
The speed must be in the range 55 - 4.2 to 55 + 4.2.
70% = 0.7
0.7 of 200 = 0.7*200
= 140
So, 70% of 200 is 140
