Find the absolute and percent relative uncertainty and express cach answer with a reasonable number of significant figures. (a) 9.23 (0.03) + 4.21 (+0.02) - 3.26 (+0.06) = "? ! (b) 91.3 ( 10) x 40.3 (+0.2) / 21.1 (+0.2) = ? (c) 14.97 (+0.05) - 1.86 (+0.011/21.1 (+0.2) = ? (d) 2.016 4 (+0.000 8) + 1.233 (+0.002) + 4.61 (+0.01) = ? (e) 2.016 4 (+0.000 8) x 10+ 1.233 (+0.002) x 102 + 4.61 (+0.01) x 101 = ? (1) (3.14 (+0.05)]1/3 = ? (g) log(3.14 (30.05)] = ?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
