Horse- 50l
sheep-4l
chicken-200ml
first you have to convert all the symbols into one, so we'll convert liters into milliliters,
1000ml=1l
horse= 50 ×1000=50000ml
sheep=4×1000=4000ml
chicken= 200ml
so now we have to multiply them by the number of animals,
h=50000ml×3=150000ml
s=4000×15=60000ml
c=200×12=2400ml
now add them together,
150000+60000+2400=212400ml
convert it into litres,
212400÷1000=212.4l
answer= 212.4 l
if we take 260 to be the 100%, what is 52 off of it as a percentage?

The answer is 49.9 because he thought of a number and added 9.5 and the result was 59.4 then you should do 59.4-9.5 and the answer is 49.9
Answer:
If x is the size of the child's head, 5 times that would be 5x and "plus 4/5" is + 4/5 so the equation is y = 5x + 4/5.
I don't get how it would be a system of equations.
