I believe it would be 4
This is because when divided by 3, 3x+12y=3 turns into x+4y=3
first speed --- x mph
return speed -- x+16 mph
6/x + 6/(x+16) = 1
times each term by x(x+16)
6(x+16) + 6x = x(x+16)
x^2 + 4x - 96 = 0
(x-8)(x+12) = 0
x = 8 or x is a negative
her first speed was 8 mph
her return speed was 24 mph
check:
6/8 + 6/24 = 1 , that's good!
It could be 30 to 31 but February has 28 expected from a leap year with 29 days
Answer:
No
Step-by-step explanation:
(x,y)=(4,-1)
73x+5y=7
73*4+5*(-1)=287
____________________________
175x−3y=17
175*4-3*(-1)=703
The answer to this problem is 16.
To solve we must follow the order of operations.
8/2 is 4.
2+2 is 4.
So, now we multiply 4(4) and will get 16 as the answer
So, 16 is the answer.
