Answer:
3
Step-by-step explanation:
Ok so
1/4 of total eaten
3/4 left
3/5 of 3/4 eaten
9/20 left
18=9/20 of whole
multiply both sides by 20
360=9 of whole
divide both sides by 9
40=whole
40 total originlly
Answer:
I don't know the answer to this one, sorry
Answer:
x : -3
Step-by-step explanation:
1) 15x-3(3x + 4) = 6 (distribute -3 to the numbers on the inside of parentheses)
2) 15x - 9x - 12 =6 (combine like terms 15x-9x = 6x)
3) -6x - 12 = 6 (add twelve to both sides, add the 12 to cancel out the 12)
4) -6x = 18 (divide the -6 on both sides)
5) x = -3
We can answer the question above by using the trigonometric functions and the concept of similar triangles.
Given that cos (L) is 4/5. The length of sides PN and NL can be solved. Please see solution below.
4/5 = NL / 15 ; NL = 12
Solving for PN,
PN² + 12² = 15²
The value of PN is 9.
Then, using the concept of similar triangles,
KN/(KN + NL) = PN/ KM
Substituting the known values,
4/(4 + 12) = 9 / KM
The value of KM is 36.
