The perimeter of the school crossing sign is 102 inches
length of each side = ?
in the question number of sides is not mentioned, so the answer may vary for the length of each side. if there is 5 sides divide 102 by 5, we get 20.4 answer so in case of 5 sides length of each side is 20.4 inches. if there is 4 sides divide 102 by 4 and we get 25.5 inches answer for the legnth each side.
Order of operations
PEMDAS
do parntheases
then exponents
then mutiply or divide, whichever coms first
then addd or subtract, whichever comes first
so
when doing parenthases, simplify innermost parenthsees first
so
2(18-(5+9)/7)
innermost is (5+9)=14
now we gots
2(18-(14)/7)
we can distribute or multiply the invisible -1 in front of the 14
2(18-14/7)
now divide because division comes before adition
remember that it is -14/7, not just 14/7 because the negative is part of the 14
2(18-2)
now simplify parenthasees
18-2=16
so
2(16)
multiply
32
the result is 32
Answer:
c=50
Step-by-step explanation:
X=1.2
y=-10.7
-x+(-y)=-(1.2)+(-(-10.7)=-1.2+10.7=9.5
Answer: -x+(-y)=9.5
1. (a) 13
1. (b) 21
2. (a) (3 + 4) • 10 / 2
2. (b) uhh i'm not sure if the expression got typo'd but im guessing it's 15 + 10 • (8 / 4)
