Answer:
2a + 4b = 44
a+b=15
Step-by-step explanation:
Call a the number of chickens, b the number of horses
We have: 2a + 4b = 44
a + b = 15
=> 2(a+b) = 30
<=> (2a + 4b) - (2a + 2b) = 14
2b = 14
=> b = 7
=> a = 8
So 8 chickens, 7 cows.
Answer:
the slope should be going from top left to bottom right not bottom left to top right
1. A = 2ab + 2ac = 2bc
2. A = 2b(a +c) + 2ac
3. 2b(a + c) = A - 2ac
4. b = (A - 2ac) / 2(a + c)
Answer:
Step-by-step explanation:
Slope = rise/run
pick two points, (0,2) (3, -7)
take their y values and subtract them
take their x values and subtract them
2-(-7) over 0-3 is 9/-3
simplify
-3
Answer:
The answer is 10 miles x/ 75= 1 / 7.5 7.5x = 75 x= 10 miles
