Celia uses the steps below to solve the equation
(-8-18d) + 20 - 24
Distribute
Step 1
over the expression in parentheses,
Step 2
Step 3
3-16d+ 20-24
Simplify like terms
3-14d=24
Subtract 3 from both sides of the equation,
-140=21
Divide both sides of the equation by --14
Step 4
Which corrects the error in the step in which Celia made the first error?
In step 1, she should have also distributed - over 2d to get 3-16d+
20 = 24

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
