This is known as a Frobenius problem, which is solved using the formula xy<span> − x – y, where x and y represent the respective frobenius numbers.</span>
If the company sells calculators only in packages of 11 and
packages of 15, then x=11 and y=15.
The largest number of calculators it is not possible to
purchase without opening a package is thus calculated as follows:
(11x15) – 11 – 15
= 165 – 11 – 15
=165 – 26
=139
If the company sells calculators only in packages of 11 and packages of 15, the largest number of calculators it is not possible to purchase without opening a package is 139
Answer:
Step-by-step explanation:
∠ABC = 1/2 ∠AOC
since we know ABC = 30° we can solve for AOC with a bit of Algebra
30 = 1/2 AOC
60 ° = AOC
:) does it make sense?
the formula about is for inscribed angles , that is an angle that touches the outside of the circle and then goes through the other side. :) Like ∠ABC
Answer:
14
Step-by-step explanation:
8 is half of 16 so times the values by two and you got your answer.
The answer to this question would be -26
Answer:
I think there is an error in the question, I assume it reads:
4x+2y=20
x+3y=50
If not, please make appropriate corrections to the question.
Answer: x=-4, y=18
Step-by-step explanation:
4x+2y=20
Simplify, divide by two,
2x+y=10.....................(1)
x+3y=50....................(2)
Multiply (2) by 2
2x+6y=100 ....................(2a)
Subtract (1) from (2a)
2x+6y - (2x+y) = 100 - 10
5y = 90
y=18..............................(3)
Substitute (3) into (1)
2x+(18)=10
2x = 10-18 =-8
x=-4 ............................(4)
Substitute (3) and (4) into (1) for verification
2x+y = 2(-4)+18 = 18-10 = 10 checks.
Substitute (3) and (4) into (2) for verification
x+3y=-4+3(18) = -4+54 = 50 checks.
Have a nice day!
