(1) let "r" denote number of rabbits, "c" number of chickens
Set up the equations:
![r + c = 1000\\4r + 2c = 3150\\\\-2r -2c = -2000\\4r + 2c = 3150\\\\2r = 1150\implies r = 575\implies c = 425](https://tex.z-dn.net/?f=r%20%2B%20c%20%3D%201000%5C%5C4r%20%2B%202c%20%3D%203150%5C%5C%5C%5C-2r%20-2c%20%3D%20-2000%5C%5C4r%20%2B%202c%20%3D%203150%5C%5C%5C%5C2r%20%3D%201150%5Cimplies%20r%20%3D%20575%5Cimplies%20c%20%3D%20425)
Answer: There are 575 rabbits and 425 chickens
(2) m - number of Mike's stamps, a - number of Andrew's stamps.
Set up equations:
![m = 4a\\m-8 = 2(a+8)\\\\4a-8=2a + 16\\2a = 24\implies a = 12\implies m = 48\\](https://tex.z-dn.net/?f=m%20%3D%204a%5C%5Cm-8%20%3D%202%28a%2B8%29%5C%5C%5C%5C4a-8%3D2a%20%2B%2016%5C%5C2a%20%3D%2024%5Cimplies%20a%20%3D%2012%5Cimplies%20m%20%3D%2048%5C%5C)
Answer: Mike has 48 stamps. Andrew has 12 stamps.
Answer:
<em>Perimeter of ABC = AB + BC+AC. Replace letters with equations.</em>
<em>3x^2-7x+2</em><em> = </em><u><em>2x^2-10x+6 + x^2-x-4 + AC</em></u><em> = </em><em>3x^2-11x+2 + AC</em><em>.</em>
<em>AC = 4x;</em>
Answer:
Slope is 2
Step-by-step explanation:
(-2, -4) and (2, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4+4)/(2+2)
m=8/4
m = 2
Answer:
To make a high estimate for the sum of two fractions, find the commnon denominator and add them.
Step-by-step explanation:
To make a high estimate for the sum of two fractions in a word problem, rhe following steps are required.
Let the two fractions be represented as and
To perfrom the operation +
Step 1 : Check if the denominators of the fraction are same. If so then, then add the numerators directly by keeping the same denominator.
Step 2: If the denominators are different, then find the common denominator between the fractions and multiply them accordingly. Then perform the addition operation.
