Let the cost of one sheep and one cow be x and y respectively.
Therefore,
5x+5y=129
10x+17y =177
Solving the two equations,
Multiply the first equation by 2 and subtract the second from the results;
10x+10y = 258
10x+17y = 177
0x-7y = 81 => y= $-11.57 (cannot be a negative value). The details of the question need to be checked.
Now,
5x+5y = 129 => 5x-57.86 =129=>5x = 186.86 => x= $37.37

Answer:
560x^3y^4.
Step-by-step explanation:
The (r+1)th term of (a + b)^r = nCr a^(n-r) b^r
We want the fifth term so r = 5 - 1 = 4:
(4 + 1)th term = 7C4 x^(7-4) (-2y)^4
= 35x^3 16y^4
= 560x^3y^4.
Answer:
154°
Step-by-step explanation:
m<LOM + m<MON = m<LON and since m<LON is a straight angle the measure of it would be 180°
9x - 91 + 6x + 76 = 180 add like terms
15x - 15 = 180
15x = 195
x = 13
m<MON is 6x + 76 replace x with 13 ➡ 6×13 + 76 = 154°
