So PEMDAS
the order of simplification/operation is
parenthaseese
exponents
multiplication or division whichever comes first
addition or subtraction whichever comes first
so we work the parenthasees inside to out
inside parenthaseese=(10-4/2)
so no exponents so skip
there's division so we do that
4/2=2/1=2
then we have
(10-2)
subtraction
10-2=8
(8)
next parenthaseese/bracket
[5 times (8)+15]
multiplication
5 times 8=40
[40]
other brackets
{390-[40]+15}
subtraction
390-40=350
{350+15}
350+15=365
outside
2 times {365} times 2
multiplication
2 times 365=730
730 times 2=1460
All you need is to solve the problem
4-2|n+6|>=2
subtracting 4 from both sides
-2|n+6|>=-2
dividing by -2 and flipping sign of inequality
|n+6|<=1
-1<=n+6<=1 subtracting 6 from both sides
-7<=n<=-5
the conjunction will be -7<=n and -5>= n
which is choice a

Answer:
Amount he must save to earn his goal = $7193.1≅
Step-by-step explanation:
The 5.5% interest is compounded quarterly, hence the compound interest expression is used
A = P(1+r%)ⁿ
A = $26000
P = ?
r = 5.5%
n = 4 x 6 = 24 quarters
P = A ÷ (1+r%)ⁿ = 26000 ÷ (1 + 0.055)²⁴ = 7193.070497956 = $7193.1≅
Its 0.454 kilograms in a pound are those the answer choices?
