3x - first number
2x - second number
2x = 24 / : 2
x = 12
3*12 = 36
answer: the larger number is 36.
If you know the measurements of 2 sides not the height , you can apply Pythagorean theorem to find the height. Square root of the sum of the squared sides
15 miles/2.5 mph=15/2.5=6 hours left
so 6 hours, 15 miles which is option D
Answer:
a
Step-by-step explanation:
Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft
