-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
This is how I understand the word problem.
Since the circle above -4 is an open circle, it means that y is not equal to -4.
Since the arrow is going to the left of -4, the numbers are all less than -4.
y < -4
Among the choices, D. y + 3 < -1 is the correct answer.
y + 3 < -1
-3 -3
y < -4

The combined land areas of country A & B are 157,973 sq km. COuntry A is larger by 773 sq kn. The land area of Country A is 79,373, the land area of Country B is 78,600.
A + B = 157,973
A = B + 773
now its just a matter of subbing
(B + 773) + B = 157,973
2B + 773 = 157,973
2B = 157,973 - 773
2B = 157,200
B = 157,200/2
B = 78,600 <=== land area for country B
A = B + 773
A = 78,600 + 773
A = 79,373 <== land area for country A
A = B + 773
now its just a matter of subbing
(B + 773) + B = 157,973
2B + 773 = 157,973
2B = 157,973 - 773
2B = 157,200
B = 157,200/2
B = 78,600 <=== land area for country B
A = B + 773
A = 78,600 + 773
A = 79,373 <== land area for country A

we know that
in a right triangle
sin ∅=opposite side angle ∅/hypotenuse
opposite side angle ∅=hypotenuse*sin ∅
in this problem
angle ∅=48°
hypotenuse=100 ft
opposite side angle ∅=?----> height of the kite from the ground
opposite side angle ∅=100*sin 48°------> 74.31 ft
the answer is
74.31 ft

Don't let the fraction confuse you.
3y + 2/4 = 7
You could multiply each side by 4 to get rid of the fraction:
12y + 2 = 28
Subtract 2 from each side:
12y = 26
Divide each side by 12 :
y = 26/12 or 13/6 or 2 and 1/6
3y + 2/4 = 7

Actually u want to find the value of 'y' step1:rearranging 3y=7-2/4 step2:take LCM and subract 3y=26/4 step3:simplify 3y=13/2 y=13/6
