The expression that represent the total amount Ilean earned last week is 27(18) + 75
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let y represent the total amount Ilean earned last week for working x hours.
Since she worked for 27 hours and earned $75 to design a web page. Hence:
y = 27(18) + 75
The expression that represent the total amount Ilean earned last week is 27(18) + 75

5x + 2 1/4 = 19 1/8
5x + 9/4 = 153/8
5x = 153/8 - 9/4
5x = 153/8 - 18/8
5x = 135/8
x = 135/8 * 1/5
x = 135/40 = 3 3/8 inches <==
Answer:
x = -15
Step-by-step explanation:
-24 + 15 - 6 = x
-9 - 6 = x
-15 = x

Answer:
Step-by-step explanation:
1. sinФ = cos 25
25 ° is in the between 0 and 90°
therefore it can simply represent
cosФ= sin (90-Ф) = sin (90 - 25) = sin 65
2. sin(Ф/3 + 10) = cos Ф
cos Ф = sin (90 -Ф)
sin(Ф/3 + 10) = cos Ф
sin(Ф/3 + 10) = cos Ф = sin(90-Ф)
Ф/3+10=90-Ф
10Ф+3/30 = 90-Ф
10Ф+3 = 30(90-Ф)
10Ф+3 = 2700-30Ф
10Ф+30Ф=2700-3
40Ф = 2697
Ф = 2697 / 40 = 67.425 ≅ 67.4°
