Add them all together and divide by the number of variables here there are four and the answer is 1.25 or 5/4
Answer:
Step-by-step explanation:
reqd.area=area of square ABCD + area of trapezoid(or trapezium)CEFG
BE=BC+CE=16+16
CD=CG+GD=8+8
A=16×16+1/2 (16+8)×16
=256+192
=448 sq. inches.
or
reqd. area=32×16-1/2(8×16)
=512-64
=448 sq. inches.
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:
they each hike 2 miles
Step-by-step explanation:
Jeff: 15=1/2
*4 *4
60 min=2 miles
Lisa: 10=1/3
*6 *6
60 = 2
To determine the slope, you can use the following formula:
(y2-y1)/(x2-x1)
