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:
They could cover 90 kilometres in 6 hours, after the terrain changed.
Step-by-step explanation:
Their speed, when they were traversing through the marsh, is:
speed = distance/time
s = 20 km / 4hr
s = 5 kmph
If their speed tripled, then it will be: 5*3 = 15 kmph
distance = speed * time
d = 15 km/h * 6h
d = 90 km
They could cover 90 kilometres in 6 hours, after the terrain changed.
to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:
you can use cross multiplication to solve for x:
so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.
If she needs 8 cups of flower for 4 eggs, when you could change that to needing 4 cups of flower for 2 eggs, now we know every 4 cups of flower is 2 eggs, and we already know 8 cups of flower is 4 eggs, so if we add 2 more eggs and that means 4 more cups of flower, the final answer is: 12 cups of flour is 6 eggs. To make it easier to remember, just remember if you have even numbers you can split them into pieces and just add those pieces over and over until you get it. We started with 8 cups of flour is four eggs, and if you put it to its smallest part It would be 4 cups of flower for 2 eggs, then you just have to remember how to count your 4’s and 2’s and it’s as easy as that
