Answer:
y=-10
Step-by-step explanation:
Answer: 36
Explanation:
• group like terms
—> 3/4m + -2/3m = 5 + -2
•find lowest common denominator
—> 3/4*3 m + -2/3*4m= 5 + -2
•multiply denominator
—> 3/12m + -2/12m = 5 + -2
•combine like terms
—> 1/12m = 3
•simplify the arithmetic
—> m= 3 over 1/12
—> m= 36
105 Animals....You know that because when you add together the head & feet that's adding all the animals together to get the total number of animals
Set it up as a direct variation equation y/x=k where k is the constant of variation. We have values for y and x and have to find k. 18/5=k, so k=3.6. Now plug in the other given y value and use that k value to find x: y/11=3.6 or
y/11=18/5, whichever your book or teacher prefers.
