y = 45
multiply both sides by 5 to eliminate the fraction
90 = 2y ( divide both sides by 2 )
45 = y
Answer:
C
Step-by-step explanation:
If x is the average (arithmetic mean) of m and 9, y is the average of 2m and 15, and z is the average of 3m and 18,
x=(m+9)/2
y=(2m+15)/2
z=(3m+18)/2
the average of x, y, and z
=(x+y+z)/3
=(m+9+2m+15+3m+18)/3
=(6m+42)/3
=2m+14
ans is C
Answer:
800m
Step-by-step explanation:
this would be solved using Pythagoras theorem
we are to find the base
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
600² + b² = 100²
b² = 10000 - 3600
b² = 6400
take the square root of both sides
b = 800m
Answer:
$60
Step-by-step explanation:
Using the given formula :
I = P × R × t
I = 40 × 10/100 × 5
I = $20
His amount in 20 years = $40 + $20 = $60
Yes it is.
2/3
2*3 / 3*3
6/9
7/9 > 6/9 = 2/3
7/9 > 2/3
Answer: Yes, 7/9 > 2/3
