Answer:
x=3
Step-by-step explanation:
y= -2
4x-3y=18
4x-3(-2)=18
4x-(-6)=18
4x+6=18
4x+6-6=18-6
4x=12
x=3

Answer:
12
Step-by-step explanation:
First, you will have to use trigonometry. Since the side of the triangleis the opposite of the angle 53 and the hypotenuse, you will use sin.
Sin 53 degrees = opposite side / hypotenuse side.
The opposite side is x and the hypotenuse side equals 15.
sin53= x/15
15 ( sin 53 ) =x
x= 11.97953
Round
x=12
1 foot = 12 inches
2 x 12 = 24 +3 = 27 inches
3 x 12 = 36 +5 = 41 inches
27*41 = 1107 square inches
1107 * 0.35 = $387.45
Answer:
40 square inch
Step-by-step explanation:
1/2+1/2= 1
1+1=2
2times 4= 8
8times 5= 40
if the problem has inches in it,
the answer will always equal to a square-inch
Answer:
9 inches
Step-by-step explanation:
The radius is 1/2 of the diameter
