278 is rounded to 280 (to the tenth). Anything that is above 5 you right. In case this is 8 so you round. If it is below 5 then you do not round.
A bird has only 2 legs, and a dog has 4 legs.
x=number of birds
y=number of dogs
We can susggest this system of equations:
x+y=18
2x+4y=50
We can solve this system of equations by substitution method.
x+y=18 ⇒ y=18-x
2x+4(18-x)=50
2x+72-4x=50
-2x=50-72
-2x=-22
x=-22/-2
x=11
y=18-x
y=18-11
y=7
Answer: we have 11 birds and 7 dogs.
Yes because the fractions denominator gets bigger the numerator gets smaller
Answer:
16+c
Step-by-step explanation:
Sum means we will have to add. When it says "sum of sixteen and c" it is telling us to add both sixteen and c together.
1.86 : 2 = 186 hundredths : 2
1.86 : 2 = 93 hundredths
1.86 : 2 = 0.93
