Answer:
x = 11/7 y = -1/7
Step-by-step explanation:
2x + y = 3
2x + y - 2y = 3 - 2y
y = 3 - 2x
x - 3(3 - 2x) = 2
x - 9 + 6x = 2
x - 9 + 6x + 9 = 2 + 9
x + 6x = 11
7x = 11
7x / 7 = 11/7
x = 11/7
2(11/7) + y = 3
22/7 + y = 3
22/7 + y - 22/7 = 3 - 22/7
y = -1/7
Answer:
The answer is 320.
the rule i used was y=32x and x represents the # of groups of tables.
Answer:
201° and 60°
Step-by-step explanation:
(2)
∠ FHG = ( arc ES + arc FG ), that is
128° = ( 55 + FG ) ← multiply both sides by 2
256° = 55° + FG ( subtract 55° from both sides )
201° = major arc FG
(3)
The measure of the secant- tangent angle FTS is half the difference of the intercepted arcs, that is
∠ T = ( arc FS - arc US )
= (170 - 50)°
= × 120°
= 60°
