56=2x
28=x
The blouse was $28
Answer:
10,000 tons of sand is being delivered.
Step-by-step explanation:
Answer:
Explanation:
x - 7y = 7
-7y = -x + 7
y = (-1/-7)x + 7/-7
y = (1/7)x - 1
6x - 7y = -28
-7y = -6x - 28
y = (-6/-7)x - 28/-7
y = (6/7)x + 4
X equals the square root of 6-x
x= the eqaution for number 2
X = 30

180 - 108 = 72
180 - 72 -43 = 65
triangle on the left
Angles = 43,65,72
triangle on the right
180 - 65 = 115
180 - 115 - 35 = 30
so angles of triangle on the right = 30, 35, 115
x = 30 (vertical angles with the other angle of triangle on the right)
