ANSWER
3438
EXPLANATION:
<em>PARENTHESIS FIRST</em>
32 x 8 = 256
17 x 4 = 68
256 - 68 = 188
(<u>now the equation is, 6³ ÷ 4 + 2 x 9 (188))</u>
<u />
<em>EXPONENTS NEXT</em>
6³= 216
(<u>now the equation is, 216 ÷ 4 + 2 x 9 (188))</u>
<u />
<em>MULTIPLICATION AND DIVISION NEXT (left to right)</em>
216 ÷ 4 = 54
2 x 9 = 18
18 x 188 = 84
(<u>now the equation is, 54 + 3384)</u>
<u />
<em>LASTLY ADDITION AND SUBTRACTION (left to right)</em>
54 + 3384 = 3438
Ta-da!
Answer:
16 minutes
Step-by-step explanation:
Because the tank already holds 5 gallons of water, you only need to find the number of minutes to fill 4 gallons of water.
Because it fills at a rate of 1/4 gallons a minute, it takes 4 minutes per gallon of water.
Since we are dealing with 4 gallons of water to be filled, we multiply 4 · 4 to get the number of minutes.
4 · 4 = 16
16 minutes
