Answer: 385
Step-by-step explanation:
Mean the three groups of 10 kids=35
Total weight of 3 groups (10x35)=350
Mean weight of 3 groups and one boy ( 35 + 350)=385
Rewrite the question, as follows:
45 is what percent of 225?
Form the ratio 45/225, and then multiply the result by 100%:
0.20(100%) = 20% (answer)
Answer:
X=1550-10y
Step-by-step explanation:
X+10y=1550
Subtract 10y from each side
X+10y- 10y=1550-10y
X=1550-10y
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints
Since we are dealing with a radical then x - 5 ≥ 0, for real values
x = 4 is less than 5 , hence is not in the domain
