Cecilia simplified an expression. Her work is shown below. (6 and one-half + 2 and three-fourths) minus 1.5 times (4.5 divided by 0.5) Step 1 9 and one-fourth minus 1.5 times (4.5 divided by 0.5) Step 2 7.75 times (4.5 divided by 0.5) Step 3 7.75 times 9 Step 4 69.75 Where did Cecilia make her first mistake?

y = x + 95

y = 42 + 95

y=137 mm hg

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

answer: your answer is a

49/6 is going to equal 8 1/6
