Answer:
1.25 minutes per lap
Step-by-step explanation:
Ok so remember
order of simplification
PEMDAS
parenthaseese
exponents
multiplicaton or division whichever comes first
addition or subtraction whichever comes first
ok so remmeber work from the left to right parenthasees first and work from inside to outer parenthasees
so first one
innermost parenthasees first so
first step is 2-4
subtract 4 from 2
second one
if xy=0 then assume x and y=0 so
(a+2)(b-9)=0
a+2=0
a=-2
b-9=0
b=9
so answe ris a=-2
b=9
third questions
innermost parenthaees first
subtract 4 from 2
ok
1. subtrac 4 from 2
2. a=-2, b=9
3. subtract 4 from 2
In the first statement, it is false. -2+14 would not add up to 16.
In the third statement, it is false. -8+-2 would not add up to 16.
In the fourth statement, it is false. -2-14 would not add up to 16.
So the second statement is true -2+18=16.
Answer:
x = 6
Step-by-step explanation:
Angle RPG = (Arc RQ + Arc SC)/2 Interior Secant Theorem
124 = (197 + 9x - 3)/2 Substitution
124 = (194 + 9x)/2 Alg
124 = 97 + 4.5x Alg
27 = 4.5x Alg
x = 6 Alg
Hope this helped! Ask me if you didn't understand something.
Answer:
