9​{[4​(y-4​)+18​]-​[2​(5y-2​)-1​]} Simplify

Mathematics
1 answer:
Delicious77 [7]3 years ago
8 0

Answer:

-54y+63

Step-by-step explanation:

9\{[4(y-4)+18]-[2(5y-2)-1]\}

Simplifying the innermost parenthesis by distribution and simplifying.

9\{[4y-16+18]-[10y-4-1]\}

9\{[4y+2]-[10y-5]\}

Now, reversing the signs of the terms inside brackets coming after negative sign to remove the brackets.

9\{4y+2-10y+5\}

Combining like terms

9\{-6y+7\}

Using distribution to remove the braces.

-54y+63

Im so confused please help me understand

The answer would be yes because 935,426>934,578

So change the sign from less than to greater than

Taylor is saying that the population in the year 2000 which was 935426 is greater than the population in the year 2010 which was 934578. It sounds more complicated than it is, they just want you to support Taylor's statement using the population numbers(statistics)

circumference= 2(pi)r OR (pi)d
d is diameter and r is radius

if the circumference is given, then you would have to work backwards.

in this case, Circumference = 78.5 ft

the equal you would use for the radius would be 78.5 = 2 x 3.14(pi) x r
- multiply 2 x 3.14 and get 6.28
- divide 6.28 on both sides to get ‘r’ by itself
- 12.5 = r

next, for the diameter you can use C= (pi) x d
- 78.5 = 3.14 x D
- divide 3.14 on both sides to get ‘d’ by itself
- 25 = d

hope this helps! make brainliest please
