I need help solving (5-6x9+6)x9+3-85 I came up with -109. Is that right

Answers

Multiply −6 by 9 to get −54.(5−54+6)⋅9+3−85Subtract 54 from 5 to get −49.(−49+6)⋅9+3−85Add −49 and 6 to get −43.−43⋅9+3−85Multiply −43 by 9 to get −387.−387+3−85
Add −387 and 3 to get −384.−384−85Subtract 85 from −384 to get −469.−469

thats what i did to get -469. show your work for finding -109 and we can compare

So we have
(5-6x9+6)x9+3-85

So this is a oder of operation question, firstly you start with the brackets

(5-6x9+6)

B. Brackets
E. Exponents
D. Division
M. Multiplication
A. Addition
S. Subtraction

(5-6x9+6)

Multiplication first

6x9=54

Now we have
(5-56+6)

56+6=62

62-5=57

((57))

Now we have left

57x9+3-85
Start from multiplication

57x9=513

513+3= 516

516-85= 413

413

Factor 20x2 + 25x – 12x – 15 by grouping.

Answers

Answer:

(4x+5) (5x-3)

Step-by-step explanation:

20x^2 + 25x – 12x – 15

From the first two terms factor out 5x and the last two terms factor out -3

5x(4x+5) -3(4x+5)

Now we can factor out (4x+5)

(4x+5) (5x-3)

A plane flew 1,000 miles away from London for one flight. For the next flight, it flew 500 miles toward London. How far was the plane from London after the second flight?

Answers

So, It First Flew 1000 Miles Away. So, It Is Positive 1000 Miles. Now, It Flew 500 Miles Closer, So Negative (closer) Distance. So, Add. 1000+(-500)
Adding Negative Is The Same As Subtracting So, 1000-500 = The Distance.
So, The Distance Away Is 500 Miles.

Answer:

500 miles
