Answer:
First question --> C) 8.5h
Second question --> D) 2
Step-by-step explanation:
First question
Terry earns $10 per hour
Jill earns 20% less which is $2 less
Jill earns $8 per hour
Jerry earns $0.50 more per hour than Jill
Jerry earns $8.50 per hour
Second question
x = 2
y = 4
(2x + 3y) / 4 - 2 = ?
Use PEMDAS
so Parentheses first, then divide, then subtract
So.... (2x + 3y) = (2*2 + 3*4) = (4 + 12) = 16
Then divide
16/4 = 4
Then subtract
4 - 2 = 2
Aprox.$3.52. if you ever need to find the percentage of something you just times it by the fraction. e.g. 60% of 5 = 5x0.6. so all you need to do to figure this out is to find 60% of 5.88 which is apporxamitely 3.52
Answer:
function
Step-by-step explanation:
The simplified form of the expression is given as 83x/56 -(97/105)
<h3>Finding the value of unknown variables</h3>
Alphabets are usually represented as unknown variables in a equation or expression.
Given the following expression shown below
6/7 x -2/3 + 3/5 + 5/8 x -6/7
Collect the like terms to have;
6/7 x+ 5/8 x -2/3 + 3/5 -6/7
Simplify
48x+35x/56 - (70-63 + 90)/105
The final expression will be given as;
83x/56 -(97/105)
Hence the simplified form of the expression is given as 83x/56 -(97/105)
