16) 12•(6+3)
17) n^6 where n is the base and 6 is the exponent
18) x / 8=8
pretend the x isn’t there and multiply the 8s by 8. /8 and •8 cancels out and 8•8=64. so ur answer is 64
19) 3•x+3•4+15
20) 34+6(25.50)
21) the student subtracted -28 instead of adding it. in order to find x, we’d need to cancel out the other number whether it’s be subtracting or adding. the correct answer should be 403.
22) the pattern is that each number is being added by 0.09
