x+y=120_______1
x=4*y_________2
x=4y
substitute 4y for x in equation 1
`4y+y=120
5y=120
eliminate the coefficient of y
y=120/5
y=24
now,input 24 for y in equation 2
`x=4y
x=4*24
x=96
thus, the numbers are
96 and 24
Answer:
(x - 2)² + (y - 3)² = 2²
Step-by-step explanation:
Standard form
(x - h)² + (y - k)² = r²
(h, k) is the center = (2, 3)
r is the radius = 2
(x - 2)² + (y - 3)² = 2²
Answer:
the flagpole is 12 ft
Step-by-step explanation:
2.5 ft / 4 ft = 7.5 ft / x ft
2.5x = 30
2.5x/2.5 = 30/2.5
x = 12 ft
Answer:
A = 81 pi ft^2
Step-by-step explanation:
The area of a circle is found by
A = pi r^2
The radius is 9
A = pi 9^2
A = 81 pi ft^2
