Use PEMDAS
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)
and |a| = a for a ≥ 0 or |a| = -a for a < 0.
|-4| - 5 · 2(-1 + 3) =-(-4) - 5 · 2(2) = 4 - 10(2) = 4 - 20 = -16
it depends :/ like it depends on the class n shi but never ever skip 2 periods inna row cuz then
u too susss. also yes
writing random exp.
for points so dont come at me

Ration of history 21 to students 49 = d)21:49
Answer:
5P= 2P+21+45 ( sum of two sides is is equal to
the opposite exterior angle)
5P=2P +61
5P-2P=61
3P=61
p= 61÷3
p=2.33333
Answer:
x=19
Step-by-step explanation:
●Alternate angles are equal
therefore, angle WYZ= angle YWX
2x= angle YWX
●Angles within a triangle sum up to 180 degrees
=3x-5+2x+90=180
▪︎group like terms
=3x+2x+90-5=180
=5x+85=180
▪︎send all x terms to one side of the equation
=5x=180-85
=5x=95
▪︎divide both side by the coefficient of x ; 5
=x=19
