The rule of PEMDAS states that Parentheses always comes first, exponents always comes second, but Multiplication and Division are equal. Because multiplication and division are equal, you work left to right and do whatever operation comes first. Multiplication and division come before addition and subtraction, which also have an equal relationship.
Therefore, if you have simplified the terms inside the parentheses first, and have done the exponents second, then multiplication would come next. So that’s the answer, multiplication.
Ratio of student to teacher = 17:3
Let the total number of students and faculty = x
Then
Number of students = 17X
Number of teachers =3X
So
17X+3X=740
20X = 740
X = 37
Then the number of students = 17*37

= 629</span>
Number of teachers = 3*37

Answer:
<h2>9</h2>
Step-by-step explanation:
(-)(-) = (+)
(-)(+) = (-)
(+)(-) = (-)
(+)(+) = (+)
-(-21) = (-)(-21) = (+)21 = 21
-12 - (-21) = -12 + 21 <em>use commutative property: a + b = b + a</em>
= 21 + (-12) = 21 - 12 = 9
Answer:
y=-2x+2
slope-intercept form --> y=mx+b
m= slope. the slope in the graph is down 2 over 1, -2/1 which is the same as -2.
b = <u>y-intercept</u><u>. </u><u> </u><u>the </u><u>y-intercept</u><u> </u><u>is </u><u>2</u><u>.</u>
