Answer:
X= 4
Step-by-step explanation:
3x+6/3=6
multiply each side by 3 to get rid of the fraction bar
3x+6=6*3
3x +6=18
-6 from both sides
3x= 18-6
3x=12
divide by three on both sides to solve for x
x=12/3
x=4
the sum of supplementary angles equals 180°
you can have an acute angle (less than 90°) + an obtuse angle (greater than 90°) equal to 180°
But you can also have a right angle (equal to 90°) + another right angle equal to 180°
Answer: (b) sometimes
Answer:
82 degrees
Step-by-step explanation:
Measure of arc ABC = 86*2 = 172 degrees.
Measure of arc DC = 360 - (145+172) = 360-317 = 43 degrees.
Measure of arc BCD = 121+43 = 164 degrees.
Measure of angle A = 164/2 = 82 degrees
Answer:
4pi r
Step-by-step explanation:
Answer:
Let the cost of orange be X and cost of cherry be y
3x + 9y = 78
8x + 4y = 58
Solving equation using elimination method
multiplying eq 1 with 8 and eq 2 with 3
8(3x + 9y ) = 78(8)
3( 8x + 4y) = 3(58)
24x + 72 y = 624
24x + 12y = 174
subtracting,
60 y = 450
y = 7.5
3x + 9(7.5) = 78
3x + 67.5 = 78
3x = 78 - 67.5
3x = 10.5
x = 3.5
<h2>Box of orange = $3.5 </h2><h2>Box of cherry = $7.5</h2>
