Jessica wanted to know how much farther she ran in Week 1. Her work is below. 15.05 minus 11.90 = 5.95. The decimals in the equation are all aligned. The 0 in 15.05 is crossed out and a 10 is above it. The first 5 in 15.05 is crossed out and a 6 is above it. What mistakes did Jessica make when solving the problem? Select all that apply. She did not align the decimal points. She did not subtract 10 aectly. She subtracted instead of adding. She did not rename correctly.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
