Answer:
x = 3
Step-by-step explanation:
The whole is equal to the sum of the parts.
DG = DO +GO
20 = (4x +1) + 7
12 = 4x . . . . . . . . . . subtract 8
3 = x . . . . . . . . . . . divide by 4
Answer:
(2,22)
Step by step explanation:
(x,22) is the solution of the equation y=9x+4
9x+4= 22
=>9x= 22-4
=>9x=18
=>x= 2
Answer:
x = 6
Step-by-step explanation:
∡J = ∡K and ∡M = ∡L
because this is an isosceles trapezoid
∡J + ∡M = 180°
because angles at opposite bases are supplementary
then ∡J + ∡M = 180°
∡J = (7x + 2)°
∡M = ∡L = (25x - 14)°
so:
(7x + 2 + 25x - 14)° = 180°
(32x - 12)° = 180°
32x = 180 + 12
32x = 192
x = 6
