Step-by-step explanation:
7 + 3 = 10
+ 679 - 2056 = -1377
- 398 + 1 = -397
-23 - 237 = 260
2 - 6 = -4
-2 × 3 × -4 = 24
absolute value of -36 = 36
6 + 4 = 10
- 5928 - 965 = -6893
215 × 212 + 212 × 314 = 112148
(15 + 5) ÷ (15 + 5) = 20 ÷ 20 = 1
-457 + 1 = -456
- 218 -1 = -219
A=35+5t, b=100-8t, a=b when:
35+5t=100-8t subtract 35 from both sides
5t=65-8t add 8t to both sides
13t=65 divide both sides by 13
t=5 minutes
a=35+5(5)=60 gallons
So the tanks have an equal volume of 60 gallons after five minutes.
